Determination of KC of Iron(III) Thiocyanato by Spectometry Theory: This study uses the method of measuring the equilibrium constant‚ Kc‚ for solution made of different initial reactant concentrations to determine the Kc for the reaction of iron(III)) and thiocyanato. The formula: Fe3+ +SCN- ⇔ FeSCN2+ The concentrations of the three substances at equilibrium will be determined by the stoichiometry of the reaction and the stoichiometric determination of the concentration of the complex AB.

Lab: investigating hooked law with springs Purpose: to find spring constants of different springs using the slope of a graph of change in heights vs. the weight force. Also‚ to be able to understand how spring constants change when you add springs in a series or paralle Pre lab predictions: We predicted that the graph of gravitational force (mg) as a function of stretch (delta x) would look like Data: Spring #1: y = 8.2941x + 0.0685 This table represents the different distances that

Changes in temperature and pH along with Substrate Concentration and Enzyme Concentration were the conditions tested in the experiment. Each lab was assigned to a group A‚ B‚ C and D in our class performed this experiment. The data presented in this report will reflect the average rates of change in O2 ml/min of our class results. In the later discussion sections‚ it will become

Enzyme Lab: Peter Kuetzing – 10/4/2012 – F Block 1. How does changing the concentration of enzyme affect the rate of decomposition of H2O2? When more enzymes is added the rate of reaction speeds up. In this case‚ H2O2 will produce more O2‚ in return the kpa/min will go up. 2. What do you think will happen to the rate of reaction if the concentration of enzyme is increased to five drops? Predict what the rate would be for 5 drops. I think that the rate of reaction will slightly increase from

Dwight “Sonny” Lewis Pr.6 Religion The 7 Sacraments The Catechism of the Catholic Church lists the sacraments as follows: "The whole liturgical life of the Church revolves around the Eucharistic sacrifice and the sacraments. There are seven sacraments in the Church: Baptism‚ Confirmation‚ Eucharist‚ Penance‚ Anointing of the Sick‚ Holy Orders‚ and Matrimony." The sacraments are symbols. A symbol is a sign (an outward reality) that represents an invisible (spiritual) reality‚ totality different

Krupa Desai Cell Biology April 3‚ 2013 Lab: Biosynthesis of Starch Introduction: In this lab we learned the concept and procedure of synthesizing starch. We also learned the effects of pH and temperature on the reaction rates of amylase.. In the process of the synthesis lab we learned phosphorylation using a potato‚ which was what we synthesized. The phosphorylation took place after the addition of primer. There are two different types of starches used are amylose and amylopectin. To test

at which a chemical reaction occurs. We looked at factors that affected the breakdown of hydrogen peroxide. These effects are the different temperatures and pH levels the enzymes were placed in. We found that the optimum‚ or best condition‚ temperature for the enzymes tested was about 22 degrees Celsius. The optimum pH level for the enzyme was 7. Introduction Enzymes are biochemical that catalyze‚ or increase the rate‚ at which a chemical reaction occurs. All enzymes are proteins that have a specific

Experiment 7 INVESTIGATING STOICHIOMETRY WITH SODIUM SALTS OF CARBONIC ACID Introduction In this experiment we are going to get a better understanding of chemical stoichiometry. We are going to be reacting sodium bicarbonate (NaHCO3) and sodium carbonate (Na2CO3) with hydrochloric acid (HCl). To start off the mass of two unknown substances (being the sodium bicarbonate and sodium carbonate) will be taken. We will need to construct balanced equations for both of the reactants with the HCl and
