...For my experiment, I used American coins dated after 1982. The metal compositions of the coins are as follows according to The United States Mint. The penny is 2.5% CU/Balance zinc (copper plated zinc). The nickel is 25% nickel/balance CU (cupronickel). The dime is 8.33% balance CU (cupronickel). The quarter is 8.33% Balance CU (cupronickel). Tarnish on coins happen when the metal combines with oxygen. Oxidation, which causes tarnish, is a chemical reaction. Oxidation also happens with reduction, which is when something gains electrons. pH (on the pH scale) stands for “the power of “H”, or hydrogen. The lower something is on the pH scale, the higher its acidity. Rust can weaken a coin or any other metal material. The green patches on coins are called copper oxide. It is caused by oxidation. When an acid reacts with tarnish, it makes the coins shiny. In order for oxidation to occur, the air has to be damp. In my experiment I used specific solutions to clean coins. Lemon juice has a ph of 2.2. Baking Soda has a pH of 8.4. Water has a Ph of 7. Orange juice has a Ph of 3.70. Cola has a Ph of 3.18. Dishwashing liquid has a pH of 7.80. Solutions with a pH less than 7 are acidic and solutions with a pH greater than 7 are alkaline or basic. Pure water is neutral and isn’t an acid or a base. pH is an important measurement used in various medical, biological, chemical, environmental, and nutritional labs. pH standards are determined using a concentration cell with transference, by measuring...

...infantrymen climbing up on the fire step, and readied themselves to guard against a dawn raid by the enemy. Both sides carried out their respective ‘stand to' and despite the knowledge that each had prepared itself for raids or attacks timed at dawn, it was at this time that many of the planned attacks were carried out. As the light grew, this daily ritual was accompanied by the ‘morning hate'. This was when both sides relieved the tension of the early hours with indiscriminate machine gun fire, shelling and small arms fire into the mist to their front, which made doubly sure of safety at dawn. Breakfast and Weapon Cleaning Following stand to the men would have their breakfast and clean their weapons. Breakfast would be brought up in containers from the field kitchens and the weapon cleaning would be done in shifts, with only a portion of the men cleaning their weapons at any one time. Inspection Breakfast would be followed by the daily inspection by the Platoon Officer and Sergeant. Weapons would be checked to ensure that they were clean and serviceable as would the men's clothing. Often this inspection would include a ‘foot inspection' looking for signs of ‘trench foot'. Trench Foot was a medical condition peculiar to trench life. It was a fungal infection of the feet caused by cold, wet and unsanitary trench conditions. It could turn gangrenous and result in amputation. Some 20,000 casualties...

...Cleaning Solution- are substances, usually liquids, powders, sprays, or granules, that are used to remove dirt, including dust, stains, bad smells, and clutter on surfaces. Purposes of cleaning agents include health, beauty, absence of offensive odor, avoidance of shame, and avoiding the spreading of dirt and contaminants to oneself and others. Some cleaning agents can kill bacteria and clean at the same time. Scrubbig foam- Scrubs away that are hard to remove such as bugs, tar, and sap. Also used as a more aggressive deoxidizer. Dishpan-a large pan in which dishes, pots, etc., are washed. Dish Cloth-A dishcloth is used in the kitchen to clean dishes and other surfaces. Typically they are made of cotton or other cloth, such as microfiber. Pan with hot water-it is a pan to place hot water on it to prevent the hot water from boiling it to your body. Rolled Newspaper-Newspaper has just the right properties to start a fire. It comes in big sheets. There is most often too much of it around. It bunches up easily. It lights easily and burns without leaving much ash. Plus plain newspaper doesn't produce a lot of toxins when it burns like some other paper products do. Cleaning Rags-Cleaning with rags is the ultimate in fabric recycling. The older the fabric the better it is because it will be soft and very absorbent. I only recycle 100% cotton or linen fabric, again because it's so absorbent. Poly fabric and poly/cotton blends won't wipe spills as well and will never reach that soft...

Mr. Knox, ABC’s shareholder, is now looking for ways to improve future profitability of the company and is wondering if the new department is profitable to remain operational.

...people, probability is a loosely defined term employed in everyday’s conversation to indicate the measure of one’s belief in the occurrence of a future event. Say, what is the chance of arriving on time if one takes the bus? takes the taxi? However, for scientific purposes, it is necessary to give the word probability a definitive, clear interpretation. One can think of probability as the language in discussing uncertainty. For instance, in tossing a coin (random experiment), the outcomes can either be {H} or {T }. If we know exactly what the outcome of the next trial will be, then we are certain that, say, a {H} will show up next. However, it is impossible to know exactly what is going to happen in reality - uncertainty. Definition. A random experiment is a process leading to at least two possible outcomes with uncertainty as to which will occur. Then, the possible outcomes of a random experiment are called the basic outcomes, and the set of all basic outcomes is called the sample space, S. Examples of random experiment (i) Tossing a coin Basic outcomes: {H}, {T } Sample space, S = {H, T } (ii) Rolling a dice Basic outcomes: {1}, {2}, {3}, {4}, {5}, {6} Sample space, S = {1, 2, 3, 4, 5, 6} (iii) Daily changes in Hang Sang Index Basic outcomes: {up}, {down}, {no change} Sample space, S = {up, down, no change} Definition. An event is a set of basic outcomes, or a collection of some basic outcomes from the sample space, and it is said to occur if the random experiment gives rise to one...

...currency in New France is simply due to a lack of a consistent currency within the colony. These playing cards issued by the Intendent of New France were used as currency in New France and is often referred to as “card money”. French coins being used a currency within the colony failed because of a shortage within of the coins with the colony (Heaton, 1928, pp.650-651). This failure of French coins to suffice as a currency within the colony and the commercial structure necessary for consumers led to card money becoming legal tender within New France. Therefore, if it were 1686 and I were in New France I believe I would accept a quarter of a king of spades if it were offered as payment for many reasons....

...than my father. Since we had a housekeeper from morning to early evening hours from Monday to Friday she did most of the housekeeping chores. However my mother would always prepare breakfast and dinner for the family, according to her tribe it was her responsibility and as a wife and a mother we all expected her to do that. Over the weekends she would clean, wash cloths with her hands and prepare meals. My father would spend his time out with his friend or in the house drinking beer. As a grown up today I am in a egalitarian marriage, my husband and I share most of the house chores. If I cook then he will wash the dishes (we don’t use a dishwasher) or vise-versa. We usually do house cleaning together on Wednesday we would have light house cleaning and on Saturday we would have heavy house cleaning. I’m the one who cleans the toilet and the bathroom I don’t like it but I like clean toilets and bathrooms so I clean them twice in a day, in the morning before I take shower and in the evening right before I take my warm beautiful shower, my husband barely cleans the toilet. Our chore distribution isn’t based on gendered lines, we have a rule which goes ‘if its not in it’s normal state someone has to do something’ Said all that you can see that we are both responsible for our house, light now we don’t have a child but my step son usually visits us on weekends.
