Goal(s): To study the effect of concentration on the rate of a reaction‚ and to find the order of the reaction in each reactant and write a rate equation. Background Theory: Chemical reactions occur at different rates that ultimately depend on their concentration‚ the temperature‚ the usage of catalysts‚ the nature of reactants‚ like the surface area of the particles. Concentration‚ for instance‚ increases the number of molecules or particles in a certain volume‚ so collisions will become more

determined‚ and compare to the freezing point of Cyclohexane with the addition of two different concentration of unknown solid. The pure substance of Cyclohexane has defined physical properties. However‚ when a solute is added these properties are determined by the amount of solute added‚ also known as colligative properties. The temperature of the freezing point was lowered when the solid was added and it decreased as the concentration of the solid increased. The molality of the solute was determined

et al Abstract: The purpose of this lab was to determine how light affected photosynthesis‚ specifically the production of O2 bubbles. It was predicted that when the light was more intense the O2 bubble production will be high. Conversely‚ when the light was less intense the O2 bubble production will be lower. Basically the plant that is closer to the light will produce more bubbles than the plant that is placed farther away from the light source. In this lab the independent variable is the light

Rachel Bohnenberger Professor Van Doorn ENVS 150-002 27 April 2015 GMOs Lab Report Introduction As the population of Earth increases exponentially‚ so does the demand for more food. One of the solutions to the question of how more food can be produced is Genetically Modified Organisms‚ or GMOs. There is an ongoing debate about whether or not GMOs are more beneficial or harmful to society. Some of the benefits to GMOs are: growing plants‚ such as corn‚ that are resistant to weeds and pests‚ larger

Stoichiometry lab 1 Purpose: The purpose of this lab is to find the limiting reactant‚ also to find the percentage yield and percentage purity of the reaction that happens between Calcium Chloride and Sodium Carbonate. The other purpose was to know how the reaction can be balanced and created. Hypothesis: In this lab we are going to see a precipitation reaction. This is a reaction where two soluble salts Sodium Carbonate and Calcium Chloride are added together and the result is the precipitation

Abstract This lab is performed in order to determine the total energy in a reaction between zinc and hydrochloric acid. The reaction is done twice‚ once to measure the heat of the reaction and again to determine the work done in the system. This is because Enthalpy equals heat plus work (∆H= ∆E+W). Heat and work can be broken down further into separate components so the equation used in lab is ∆H=mc∆T + PV. Many calculations are used in the lab to find out what cannot be measured directly (ex:

Introduction In the amylase lab‚ it was being tested if amylase‚ an enzyme found in saliva‚ would be denatured by being put in an acid or high temperatures. This lab is about denaturing amylase. It is tested by exposing it to pH and temperature changes. It is then mixed with Benedict’s solution‚ is a solution that changes color from blue to reddish brown when maltose is present. Amylase breaks starch into maltose‚ so is the amylase isn’t denatured‚ it should change colors. Amylase is an enzyme

Enzymes are catalytic proteins that speed up chemical reactions by lowering the activation energy of the reaction. our body cells depend highly on enzymes to complete many important functions‚ such as digestion and metabolism. Enzymes are selective‚ in which each enzyme can only speed up a specific reaction. There are molecules that enzymes work with called substrates. substrate bind to an area of an enzyme called active site. There is specificity between the enzyme and substrate that react with
