the normal 30 minutes which could mean that the potatoes did not go through the whole process of osmosis. Also‚ a lot of the experiment was rushed as we were under pressure to finish as quickly as possible. Unfortunately the time constraint was caused by and outside influence unrelated to the lab itself‚ and so next time we could do a lab under normal conditions where there are no outside disturbances. There were weight differences in the potatoes which could have caused thicker potatoes to absorb

Enzyme Lab Report Introduction The objective of this experiment was to determine if changes in pH or temperature affected the activity of enzymes‚ specifically the enzyme sucrase. Enzymes are protein molecules that act as biological catalysts to increase the speed of the reaction or to lower the activation energy of that reaction. However‚ the activity of an enzyme can be affected by physical factors such as pH and temperature because these factors alter the structure of the enzyme (Freeman‚ 2011)

potential to damage crops extensively‚ and thus‚ damage society as well through shortage of food or even famine. In addition‚ in countries that depend on the production of agricultural goods like Canada‚ the effects of acid rain can be tremendous. In this lab‚ we have chosen to examine the effects of acidic and basic environments on radish plants (Raphanus sativus)‚ by implementing varying pH levels of buffer solution into the soil. We have allotted a total of four days (Tuesday‚ April 10‚ 2012- Friday April

Formal Lab Report #1 I. Basics Title of the Experiment: The Empirical Formula of an Oxide Authors: Section Number: Chemistry Location and Date II. Abstract The aim in this lab was to determine the empirical formula of an oxide of magnesium through combustion in air. This was achieved by heating an established mass of magnesium in air inside of a crucible‚ ultimately attaining a compound that contained Mg and O. The major result of the experiment was the empirical formula of the oxide of magnesium

EFFECT OF TEMPERATURE ON THE RATE OF CATALASE REACTION IN HYDROGEN PEROXIDE INTRODUCTION Enzymes function similarly to a lock a key mechanism where only one specific key will work (U and Fischer‚ 1994). An enzyme is a macromolecule that acts to increase the rate of either a substrate breaking down into two or more products‚ or where two substrates join up to form one product (Dundon‚ 2018). These enzymes perform this by lowering the activation energy required for the reaction to occur under normal

Experiment :12 Vapor Pressure and the Heat of Vaporization Nicole Petersen TA: Ryan Dixon 4/16/2013 Purpose: Use experimental techniques to record temperature and volume data for known and unknown compounds. The liquid and gas are going to be at equilibrium. We will also determine the boiling point for the known and unknown. Then use a graph to calculate the slope and then use Clasius- Clapeyron equation to find the heat vaporization. Procedure: Refer to pages 155-167 of Chemistry 1210 General

Anna Marie Marie 1 Mrs. Hartzog Advanced Placement English III 7 April 2014 How to Find Vital Signs: Pulse‚ Temperature‚ and Blood Pressure Typically vital signs are taken during the admission into a hospital or emergency care center‚ or even during a checkup. These are important in determining the wellbeing of a patient because they display in numbers how one is feeling or reacting to certain medications and treatments. There are “norms” or normal numbers and when a patient

8-26-10 1st period Density Lab The purpose of this lab was to find the mass‚ the length‚ the width and the height of 4 different cubes so we could calculate the volume and density of them. We also had to find the density of irregular shapes by dropping them into a graduated cylinder than subtracting the starting water volume by the ending water volume. Density is how much mass is in a certain volume of matter. Volume is the amount of room that an object takes up. Mass is

This lab activity will go over environmental factors that affect the folded structure of proteins. We used a raw egg and noted the changes that happen when there were changes in temperature‚ pH levels‚ and salinity. Five eggs were cracked open and placed into different bowls with different solutions placed into each bowl. What we looked at was the process of denaturing of proteins seeing how it affected the composition of the raw egg between the yoke and white portion. My hypothesis for this experiment
