the differences between water and alcohol

1. you could try burning. alcohol is extremely flammable, whereas water will put out a fire
2. alcohol has a smell, water does not.
3. alcohol will evaporate quickly, water will just sit.
4. pH test, water will be neutral, alcohol will be acidic.
5. you could dye one of them with food coloring and mix them. the alcohol will be the one on the top, because alcohol is less dense than water. 2. Water: molecular mass of 18.015, density of 1 g/cm³ at 4°C, refractive index of 1.3330, solid form less dense than the liquid form, amphoteric properties, boiling point of 100°C at atmospheric pressure, not flammable.

Alcohol: molecular mass of 46.07, density of 0.789 g/cm³, refractive index of 1.36242, solid denser than the liquid, slightly more acidic than water, boiling point of 78°C at atmospheric pressure, highly flammable

Water (along with life) is what sets our planet apart from our neighbors and it is the topic of this chapter. The hydrosphere is the watery part of the Earth, but this is a little misleading since it gives the impression that there is one place where water occurs. Instead, water is everywhere, or nearly so. Water is present in the atmosphere, in the form of vapor, liquid, and solid. It is tied up in rocks, locked away in the crystal lattices of minerals that make up rocks; it occurs in the innumerable small pore spaces of rocks, from the surface to depths greater than 5 km. Water is also tied up in living organisms; humans, for example, contain about 70% water. Water is stored in ice sheets large and small, it occurs in various surface water bodies, and, of course the oceans, the reservoir of the great majority of Earth's water. The hydrosphere, then, is intimately tied up with all of the other spheres that make up our whole Earth system.

...Laboratory Activity 1 DIFFERENCES BETWEEN ORGANIC AND INORGANIC COMPOUNDS          Compounds that consist of carbon atoms and their molecules are known as organic compounds. This is the reason why Organic Chemistry is basically defined as the study of compounds of carbon. The electronic structure of the carbon atom shows that it has four valence electrons or electrons that are capable of forming chemical bonds. An atom, to be stable, must have four pairs of valence electrons or a total of eight electrons at its outermost energy level. There are two ways by which atoms can complete this configuration in the outermost energy level:  1. An atom may share electrons with other atoms so that with the shared electrons it acquires a complete outermost shell. The chemical bond formed is called a covalent bond. 2. An atom may lose or gain enough electrons to acquire stability of configuration. In the process, one atom becomes positively charged and the other negatively charged. These charged atoms are called ions. Therefore the chemical bond formed is known as ionic bond, a very strong chemical bond.        Most organic compounds are covalent compounds. They are weaker or they easily yield to chemical reactions, e.g. combustion, and substitution. They have higher melting points compared with most inorganic compounds. They decompose and produce charcoal at moderate temperatures. Due to the nature of their chemical bonds, few ionize in water, therefore most organic compounds...

Physics

...that substance gain more energy and vibrate more. These particles then bump into neighboring particles and some of their energy is transferred to them. This process continues and energy is eventually transferred from the hotter end to the colder end of the object. * Thermal convection is transferred from hot places to cold places by convection. Convection occurs when warmer areas of gas or liquid rises to cooler areas of that gas or liquid. The cooler gas or liquid replaces the warmer areas that have risen higher. This results in a continuous circulation pattern. For example Air above the respective land and water surfaces is warmed or cooled by conduction with those surfaces. During the day, the warmer land temperature results in a warmer and therefore, less dense and lighter air mass above the coast as compared with the adjacent air mass over the surface of water. As the warmer air...

Classification Tests for Hydroxyl- and Carbonyl- Containing Organic Compounds

...were n-butyl alcohol, sec-butyl alcohol, tert-butyl alcohol, acetaldehyde, n-butyraldehyde, benzaldehyde, acetone, acetophenone, and isopropyl alcohol. Each of the samples were tested through solubility test of alcohols in water, Lucas test, Chromic acid test or the Jones oxidation test, 2,4-Dinitrophenylhydrazone (2,4-DNP) test, Fehling’s test, Tollens’ silver mirror test, and Iodoform test. Solubility test of alcohols in water was used to determine the amount of water needed for it to produce a homogenous dispersion and determine whether what kind of alcohol is soluble and insoluble in water. Lucas test was used to differentiate primary, secondary, and tertiary alcohols. Chromic acid test was used to determine if the sample is oxidized and can also be used to differentiate ketones from aldehydes. 2, 4-Dinitrophenylhydrazone test was used to differentiate aldehydes and ketones. Fehling’s test and Tollens’ silver mirror test was used to determine whether the sample is an aldehyde. Lastly, Iodoform test was used for classification of methyl ketones. INTRODUCTION Hydroxyl compounds are those containing the hydroxyl group –OH. They can be classified into primary(1o), secondary(2o), tertiary(3o) alcohols, and phenol. Primary alcohols are those in which the hydroxyl group is attached to the carbon with only one carbon attached. Secondary alcohols are compounds in which the -OH is attached to a carbon which has two other carbons attached to it. Tertiary alcohols are compounds...

Simple Distillation Lab Report

...little to no separation between the organic compounds, the impurities remained in the distillation flask. The impurities were later removed before extraction. Extractions were performed to further purify the distillate of the alcohols and sulfuric acid. Water was able to remove the leftover alcohol from the solution, which resulted in the water spikes in our NMR and IR spectrums. Water was able to remove the leftover alcohol because water is a polar molecule and the hydroxyl groups are attracted to the layer that is more polar. On the separatory funnel, there were three layers, organic layer (product layer), aqueous layer, then once again the organic layer. The product was formed on both the top and bottom layer even though they were only supposed to form on the bottom layer of the separatory funnel because the products are denser than water. If the organic layer converged at the top of the aqueous layer, it indicates that the reaction did not proceed as much as it should have and contained alcohol. Since the product was at both top and bottom layer, it means that some of the reagent was went through the reaction like it was supposed to and has no alcohol, but some reagents did not and contained some alcohol. The product was then washed with sodium bicarbonate to remove the acids in the organic layer, which produced salt and carbonic acid, which decomposed to water and CO2. The polarity of the C-Br bond allowed the organic layer to cling onto water molecules after the separation...

An ionic or electrovalent bond results from the electrostatic attraction between metal and non-metal atoms by the transfer of electrons. _____________________________________________________________________________________ Introduction The atoms in a compound are held together by a chemical bond. There are two types of chemical bond: ionic and covalent bond. An ionic or electrovalent bond results from the electrostatic attraction between metal and non-metal atoms by the transfer of electrons. One example is the formation of bond between a sodium metal atom and a chlorine non-metal atom [1]. In contrast, covalent bond involves the sharing of valence electrons between non-metal atoms. A covalent bond becomes polar when there is unequal sharing of bonding electrons. This happens when the elements involved in the bond has a significant difference in their electronegativity, such as in hydrochloric acid, HCl. Equal distribution of bonding electrons leads to the formation of a non-polar covalent bond. This happens when there is small or no difference in electronegativity between the atoms in a bond. Chlorine gas, Cl2, has a non-polar covalent bond. Electrical conductivity, the flow of electric current, can be used as a basis for determining the type of chemical bond present in a compound. An ionic compound...

Substance Abuse Among Women Essay

...attention by the researchers and treatment providers and general public. However, it does not mean that women are not using or abusing substances or substance abuse among women were not exist in older days. Addiction cannot stay hidden because women are also equally vulnerable for substance addiction. This was evident when the national survey of the United States evidenced that drug use among women was increasing at a rate higher than for men, though men were still more likely to become addicted to drugs and alcohol than women (Westermeyer, & Boedicker, 2000; & Stein and Cyr, 1997). Recent literatures proved that though both men and women are equally vulnerable for substance addiction there is a clear difference among men and women substance users. A large number of researches suggest that women differ from men in a number of areas relating to alcohol and drug use the gender differences are reflected not only biologically but also in psychosocial dimensions too. The gender difference manifest from etiology of substance abuse to biopsychosocial consequences of substance abuse and also the treatment of substance abuse. Epidemiological...

...issues around the world. In order to understand each factors, (Germov,2009) explains that history refers to how the past influences the present. Culture refers to how culture impacts on our lives. Structural factors refers to how particular forms of social organisations such as media, politics, technology, etc affect our lives while critical factors refers to how we can improve our actual environment. Based on my readings about Thailand as well as Australia, I found that there are extreme differences between the two. Even though Thailand is still developing while Australia has already developed, in Thailand there is a high risk of developing numerous infectious diseases due to malnutrition, poverty, hunger, agriculture, pollution, poor sanitation, HIV/AIDS and other diseases, no electricity supply, social and cultural exclusion, war, poor water quality, and inadequate health care food (Nikhil Ghimire, 2014). While people living in Australia have access to education, technology, food, clean water, public health settings, etc. Therefore the risk of developing infectious diseases is much lower yet it has other health issues which are predominant, such a cardiovascular diseases, cancer, obesity, Alzheimer, etc. Thailand, as well as many other developing countries suffers from diseases such as TB, cholera, HIV,...

Microwave-Assisted Enzymatic Hydrolysis of Rice Straw Using Effective Microorganisms for Bioethanol Production

...INTRODUCTION Background of the Study The evolution of industrialization and mechanization in the 21st century made it possible to transform manual equipment into modern machinery. With this development, global reliance on petroleum-based fuel is constantly increasing, giving rise to a challenge on energy sufficiency. Negative impacts, such as greenhouse gas (GHG) emissions, are associated with the combustion of these petroleum-based fuels (MacLellan, 2010). Major GHG contributors identified by the United States Environmental Protection Agency (EPA) include industry (20%), residential and commercial (11%), and agriculture (8%) (Bogart, 2013). Adverse effects on health and the environment of using petroleum-based fuels, thus, urge scientific community to search and develop alternative renewable fuel to replace the current and existing petroleum-based fuels. Biofuels have been demonstrated by several researches to reduce GHG emissions as compared to gasoline (petrol) (Leen, 2012). Among the alternative biofuels, bioethanol has received considerable attention in transportation sector because of its utility as an octane booster, fuel additive, and even as neat fuel (Mudliar, et. al., 2009). Bioethanol can be derived from organic materials, such as energy crops like corn, wheat, sugar cane, sugar beet, and cassava, among others (Neves, et. al., 2007). However, due to their primary utility as food, these crops cannot provide the global demand for bioethanol production. Among...

...with functional groups attached to the chain. The functional group gives the molecule its properties, regardless of what molecule contains it.[1] Examples of functional groups are that of hydroxyl (-OH) which is usually seen in alcohols, and carbonyl (C=0) which is seen in aldehydes and ketones. In this experiment, several tests were conducted to distinguish and differentiate various sample compounds such as ethanol, n-butyl alcohol, sec-butyl alcohol, tert-butyl alcohol, benzyl alcohol, n-butyraldehyde, benzaldehyde, acetone, acetophenone, isopropyl alcohol, and acetaldehyde. The tests are the following: solubility test of alcohols in water, which gave a soluble result in ethanol, sec-butyl alcohol and tert-butyl alcohol. Next is the Lucas test, which is used to differentiate 1°, 2° & 3° alcohols. In Lucas test, tert-butyl alcohol gave an immediate turbid result; the rate of reaction was noted. Chromic Acid test (Jones Oxidation) which gave a positive result by producing a blue-green solution with the sample n-butyl alcohol, acetaldehyde, benzaldehyde, and isopropyl alcohol. 2,4-Dinitrophenylhydrazone (2,4-DNP) was used to detect presence of carbonyl groups. In this test, only acetophenone gave a red-orange precipitate. The tests to identify between aldehydes and ketones are Fehling’s test and Tollen’s Silver Mirror test. In Fehling’s test, it gave a brick-red precipitate in n-butyraldehyde and benzaldehyde; while in the Tollen’s Silver Mirror test it produced silver...

Dehydration

...Water makes up more than half of the human body and is required for our cell systems to properly perform their necessary functions. Dehydration occurs when more water is lost than what is being taken in. Making sure we have the proper amount of fluids in our cells is vital to ensuring our bodies are able to properly perform their essentially necessary functions. Water acts like a cleanser, helping with the removal of harmful waste and possible deadly toxins. Our blood, which is made primarily of water, is responsible for carrying many nutrients to nearby waiting cells. Our immune system, which contains a fluid called lymph, is also made of water. If our immune system is affected by dehydration, it stops working properly and our body will not be fully capable of fighting off the harmful effects of illness and disease. Water also plays a vital role in the digestive process, by aiding in the break down of foods and liquids and the transportation of those food particles through the entire digestive system. Water is an important component concerning the process of producing and passing excess body waste. Another important role water plays is in regulating normal body temperature. When our internal organs get too warm, we begin the process of perspiration; pushing water out through pores in the skin, in an attempt to remove excess heat and regulate a normal body temperature. If our cell system is not properly, and continually hydrated we may begin feeling the minor symptoms...
