rate change over time? How does this compare to a real enzyme? The enzyme’s rate did change over time. This compares to a real enzyme because an enzyme’s job is to speed up the reactions and as time allotted. That did happen since the enzyme in our lab was able to make more chainobeads as time progressed. 4. Graph 5.

Acid Base Titration Purpose: The purpose is to calculate the molarity of a NaOH solution by titrating the base with 5mL of standard HCl solution in each trial. By adding the base with unknown molarity to the acid with 0.10M the molarity of NaOH can be calculated. The base‚ NaOH‚ helps bring the pH of the acid‚ HCl‚ closer to seven‚ which neutralizes it. When using the buret the amount of NaOH used is able to be determined. Then by writing a balanced chemical equation and using the titration

reaction equation is as follows: Rate of reaction = k [H202]M [I-]N The value of m and n will be calculated from the various runs of the experiment holding either H202 at constant concentration or holding I- at constant concentration Experiment: My lab partner and I first assembled the apparatus that we were to use according to the sample that was used to show us how to conduct the experiment. We added room temperature water into the leveling bulb and filled until the bulb was about half way filled

Name Lab‚ Week #1 BALANCE LAB Introduction Several instruments are used for determining the mass of a chemical; these instruments are called “balances.” However‚ different balances have different measurements‚ meaning that some balances are more accurate than others. Moreover‚ there are several techniques that are used or practiced in order to obtain an accurate measurement. The two techniques are direct weighing and weighing by difference. Direct weighing simply means to read the mass

Lab Report Problem: What method would consistently test the foam and ensure it has the correct density? Background: There are words that need to be understood before executing the experiment. The first thing you need to know is density. Density is a measure of mass per unit of volume. The reason for testing density of doors because doors must contain a density of 14.34lbs per ft3 of foam‚ or it will collapse if the density is too high. If the density is too low‚ it won’t allow for normal expansion

Abstract This lab was focused on determining the optimal temperature of the enzyme amylase responsible for catabolizing starch polymers and to see how different temperatures affected the rate as well as how effectively the enzyme worked. To proceed with the experiment the group set up four different test tubes for each‚ bacteria and fungal amylase‚ and labeled them accordingly with different temperatures as well as different solutions . Then the spot plates were placed on the time and temperature
