Behavior of Gases and Absolute Zero Determination Lab Report Experiment 4 Introduction In this experiment we measured the relationship between temperature‚ volume‚ and pressure. Objectives: Conduct a set of experiments‚ each of which illustrates a gas law. Gather data to identify the gas law described by each activity. Complete the calculations necessary to evaluate the gas law in each activity. From your results‚ derive a single mathematical relationship that relates pressure‚ volume‚ and

Alyssa Caparelli Organic Chemistry 12A Professor Alston October 28‚ 2014 Isolation of Chlorophyll and Carotenoid Pigments from Spinach Purpose The purpose of this experiment was to isolate ß-carotene‚ chlorophyll-A‚ and chlorophyll-B from spinach using column chromatography. Spinach was dehydrated using ethanol‚ and the pigments were extracted with dichloromethane. The spinach extracts were dried using CaCl2. Then‚ the solid pigments were run through a column using a non-polar solvent‚ hexane

Title- Protista Lab Concept- the concept of this lab was to explore what is in the pond water as living organisms and try to identify what it is. Some types of Protista are multi-cellular like giant kelp. Although they look much like plants‚ multi-cellular protists lack specialized tissues. Being eukaryotes‚ they have a membrane-bound true nucleus with linear chromosomes‚ and they have membrane-bound organelles. The kingdom Protista contains all eukaryotes that are not plants‚ animals‚ or fungi

Fly Lab Shannon Ladd Introduction: Famers and herders have been selectively breeding their plans and animals to produce more useful hybrids for thousands of years. It was somewhat of a hit or miss process since the actual mechanisms governing inheritance were unknown. Knowledge of these genetic mechanisms finally came as a result of careful laboratory breeding experiments carried out over the last century and a half. A contributing geneticist named Gregor Mendel (1822-1884)‚ discovered through

Enzyme lab report. Introduction. An enzyme is a protein molecule that speeds up the rates of chemical reactions by many folds. They recognize‚ bind‚ and change specific reactants. They do not change thus can catalyze the same reaction again and again. Activation energy also known as an energy barrier is the amount of energy needed in order to begin a chemical reaction. Catecholase catalyzes the reaction rate of catechol oxidation. Catechol is found beneath the skin of many plants such

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

ABSTRACT: This lab allows us to observe the conversion of hydrogen peroxide (H2O2) into water and oxygen gas. An enzyme known as catalase facilitates this decomposition reaction. The catalase enzyme acts as catalysis‚ helping lower the energy needed to activate the reaction while the enzyme itself is not affected. Catalase is a digestive enzyme used to break down hydrogen peroxide‚ which is a normal byproduct of cellular respiration. The reaction could take place without the help of catalase‚ but

Assignment One - Case study‚ Hindustan Computers Limited (HCL Technologies) Behaviour modification strategies. Behavior modification strategies are based on the principals of operant conditioning and reinforcement theory‚ which take the view that learning is influenced by the environment. The renowned psychologist B. F. Skinner expressed that through operant conditioning‚ people’s behavior could be shaped by reinforcement or lack thereof. According to Wood‚ et al‚ a reinforcer is a stimulus

Through this process‚ they are considered very unique because they are not altered or consumed within the reaction (Lab Manual 3 pg. 1). This is why enzymes are considered biological catalysts. They also do not alter the equilibrium of a chemical reaction nor the amount of free energy that is released (Lab Manual 3 pg
