... active site cannot bind with any subtrate anymore.Amylase breaking down the starch suspension into maltose and maltose into glucose when HCL was added into solution B .This is because solution B was hydrolyzed and the H+ ions present break down the bond in between molecules of the solution B The HCl will denature (unfold) the amylase (as noted at the bottom of the link you provided), disrupting the shape of its active site, therefore it won't work anymore.  In table 1,2solution is used which is carbohydrate solution A and B.When solution A tested with Benedict”s solution ,it will form brick red precipitate.From this test,it shown that it is reducing sugar.When it tested with iodine solution,the yellowish iodine solution turn to colourless.That is no starch present.When solution B is tested with Benedict”s solution,that is no change.This result shown that it is non-reducing sugar whereas when solution B tested with iodine ,the purpulish black colour of solution turn into blue black.Starch is presented.

.... Hence, there is a positive error of 0.02 ms-2. There are many ways to improve this experiment. One of them is by taking repeated readings. This would help determine the correct reading of the experiment. Next, is to avoid parallax error. Be sure that the eye contact of the observer is directly proportional to scale of the measuring instrument. This would help avoid parallax error. Another way of improving the experiment is by using different instruments to make the measurement. This would give a more precise value of the reading hence reducing the errors due to measuring instruments. Projectile is applicable in daily life. An example of projectile motion applied in daily life is playing golf. When a golf ball is hit by a golf club the movement of the golf ball is due to projectile motion. Another example of application of projectile motion in our daily life is playing basketball. When a basketball player shoots the ball towards the net, the movement of the ball is parabolic, thus involving projectile motion. Projectile motion is also involved in the sports of short put. Projectile motion is also applied when fishing. When casting a line the technique for the angler to quickly flick the rod from behind toward the water involves projectile motion as well. Conclusion: This experiment was carried out to investigate the trajectory of a two dimensional motion by investigating the trajectory of a small ball as it rolls off a surface inclined to the horizontal.

..., Bunsen burner, tripods, gauzes and beakers to cool down before handling them.  Keep long hair tied and do not wear dangly earrings.  Do not allow electrical equipment to come into contact with water.  If you are not sure about how to carry out a scientific procedure, ask the lecturer or lab officer.  Make sure you understand the rationale and consequences of your actions before you act.  Follow all safety instructions given in the manual or provided by the lecturer/tutor for particular experiments (e.g. use of gloves or mask). Making Accurate Observation The experiment will make it clear about the needed observation, e.g. the color changes when two solutions are added together or time taken for a chemical reaction. Ensure that you know the proper handling of relevant equipment before the start of experiment. Think carefully about the precision of your observations. You may need to find out reference for color description from external sources (e.g. reference books or online references) before the practical session. Recording Results in an Appropriate Form Results can be recorded in various ways. Often it is helpful to record raw data in a table. Most data will be in the form of numbers, e.g. quantitative data (also known as numerical data). However, some data, e.g. color of solution, are qualitative. Bear in mind that the best way for data collection is to avoid missing out any observation you have made, and keep your raw data in safe......

... electrons and group number for the A group (main group) elements. Recall that the number of valence electrons for any main group element is equal to the group number for that element. Flashback 7.3 Electron Configuration of Elements EXAMPLE PROBLEM: Lewis Symbols for Atoms (a) Draw the Lewis symbol for Te, tellurium. (b) The following Lewis diagram represents the valence electron configuration of a main-group element. Identify the element in period 5 that has this valence electron configuration. SOLUTION: Te (a) Tellurium is a Group 6A element and has six valence electrons. (b) Rb The element has one valence electron, so it is a Group 1A element. Rubidium is the Group 1A element in the fifth period. OWL Example Problems 8.3 Lewis Symbols for Atoms The representation of H2 shown in the previous section where the bonding electron are represented with a line, H—H, is the Lewis structure of H2. In a Lewis structure, pairs of bonding electrons are represented as lines connecting atom symbols, and nonbonding electrons are shown as dots (Figure 8.3). Nuclei and core electrons are represented by element symbols. Notice in Figure 8.3 that there can be more than one bonding pair between atoms, and that nonbonding electrons usually appear in pairs (called lone electron pairs or lone pairs). A bond consisting of two electrons (one line) is called a single bond, a bond made up of 4 electrons (two pairs, two lines) is called a double bond, and a bond with 6 electrons (three pairs,......

Investigation of Action of Saliva and 3 M Hydrochloric Acid in Two Carbohydrate Solutions

...Enzymes are biological catalysts that carry out thousands of chemical reactions that occur in living cells. Most of them are proteins. They speed up metabolic reactions in the body but remain chemically unchanged themselves In the experiment, the enzyme amylase was involved.this enzyme takes part in the digestion ofcarbohydrate. digestion is the break down of large complex and insoluble food into small simple soluble molecules for the body to absorb it. starch is a complex, the body have to find a way to break down starch, so the body produces salivary amylase in the mouth to begin the break down of starch into maltose. As the temperature rises, reacting molecules have more and more kinetic energy. This increases the chances of a successful collision and so the rate increases. There is a certain temperature at which an enzyme's catalytic activity is at its greatest . This optimal temperature is usually around human body temperature (37.5 oC) for the enzymes in human cells. Above this temperature the enzyme structure begins to break down (denature) since at higher temperatures intra- and intermolecular bonds are broken as the enzyme molecules gain even more kinetic energy.Also Enzymes have an active site. This is part of the molecule that has just the right shape and functional groups to bind to one of the reacting molecules. The reacting molecule that binds to the enzyme is called the substrate.At high temperature,the active site is said to be......
