4-4 Boiling Point Elevation If you dissolve a substance such as ordinary table salt (NaCl) in water‚ the boiling point of the water will increase relative to the boiling point of the pure water. In this assignment‚ you will dissolve a sample of NaCl in water and then measure the boiling point elevation for the solution. 1. Start Virtual ChemLab and select Boiling Point Elevation from the list of assignments. The lab will open in the Calorimetry laboratory with a calorimeter on the lab bench

Ayaan Nadeem SBI 4UO-A Tuesday‚ February 27‚ 2013 Ms. Balmer Pineapple Jelly Enzyme Lab Discussion After completing the Pineapple Jell-O Enzyme lab‚ the final results were that the canned pineapple formed the jelly while the fresh pineapple did not. Pineapple In order for this to have occurred‚ there has to be a comparison between fresh and canned pineapple in terms of their physical and chemical properties. The physical properties of fresh pineapple are that it is sweet‚ ripe and raw.

Introduction Enzymes are proteins that are involved in all the chemical processes in living things. As they are made of proteins they are affected by pH and temperature. Enzymes are catalysts; they speed up chemical reactions without being changed themselves. Digestive enzymes speed up the breakdown of large food molecules into smaller ones so that the blood can absorb them. Enzymes turn a large starch molecule into thousands of tiny glucose molecules. Enzymes end in ’ase’. There are thousands of

Enzymes are biological molecules (proteins) that act as a catalyst and help complex reactions occur everywhere in life‚ for example a piece of steak that is being digested into energy. Molecules found at the beginning of the process are called substrates‚ and these enzymes exchange them into differing molecules known as products. Nearly all-metabolic processes in a cell need enzymes in order to function at rates that are fast enough to sustain existence. Those who are lactose intolerant are simply

pH Affecting on Amylase Enzyme Is there a difference in the concentration of pH in the amylase enzyme activity? The null hypothesis would be that there will be no difference in the concentration of pH and alternative hypothesis would be that there will be a difference in the concentration of pH. The predication if that there will be a difference in the concentration of pH. The pH affects on enzyme activities‚ one of the enzyme that was used in the process was amylase.

Lab 4 Tissues Purpose: The purpose of this lab is to disover Histology or the study of tissues. Tissue make up a large part of our bodies and in this lab we will learn about the different types and functions of tissues. Hypothesis: I believe at the end of this lab If I am willing to do the reasearch the I will be able to use a mircoscope to look at different tissue samples and learn about the many types of tissue cells and their functions.
