Saliva Lab Since the amylase enzyme is present in saliva‚ starch digestion begins in the mouth. Salivary amylase changes the polysaccharide starch into many disaccharide molecules of maltase (a simple sugar) which are further broken down into glucose units by maltase enzyme in the As stated above‚ saliva contains the amylase enzyme which begins the breakdown of starches. The efficiency of starch digestion by amylase can be measured by how much simple sugar it produces under

Boyle’s Law Lab Purpose: To determine the relationship between pressure exerted and volume of a gas. Materials: Lab simulation. Procedure: 1. Open animation file 2. Modify the number of books that press down on the piston starting from 0 books and increasing by 1 each time until 19 books. 3. Record the pressure (# of books) and volume for 19 different pressure values. 4. Record those values in a table 5. Using the data‚ plot a graph of pressure in function of volume. Conclusion:

Williams‚ Brandon Physics‚ Period 1 23 May‚ 2014 Resonance Lab Purpose: To determine the speed of sound using the resonance method‚ temperature method and percent error. Hypothesis: If the temperature of the room’s 20 degrees C‚ then using the temperature method‚ the speed of sound is 344m/s. Vs – Vo + 0.6m/s T / C = 332 m/s + .6 m/s (20 C) / C = 344 m/s Conclusion: Using the resonance method the speed was 330 m/s. using the average temperature

Pre-Lab Work Sheet Which type of compound usually has higher melting points: ionic compounds or covalent compounds? What is the reason for this difference in melting points? (3 points) Ionic compounds have higher melting and boiling points than covalent compounds. The electrostatic attraction in an ionic bond is very strong hence a lot of heat energy is required to break it down‚ ionic bonds have high melting and boiling points. In covalent bonds‚ the intermolecular forces are very weak and

esterification reaction that was carried out in this lab is shown in figure 1. It worth mentioning that the by-product of such reaction is water. In organic chemistry‚ the reaction in which water molecule is released is known as condensation reaction (Hornback‚ 2006). Figure1 is drawn using Chem Sketch software. a) b) Figure 1: Typical Fischer esterification reaction (a) in comparison to the specific esterification reaction used in this lab (b) The reaction can also be categorized in terms of

points are properties that can easily be determined and help in identifying a substance. These properties can be found in chemical literature ad reference tables‚ and can be used to distinguish a pure substance from many other pure substances. In this lab you will use the pure substance Paradichlorobenzene and determine its melting an freezing points by warming and cooling a sample of the substance‚ then plotting heating and cooling curves and analyzing them. Data that you collect will represent the
