Josh Huggard Mr. Neale SBI3U1 November 6th‚ 2014 Spit and Armpit Lab Partners: Kara Washer and Josh Young Abstract This lab shows the use of salivary amylase with strong and weak starch mixtures to break down complex carbohydrates into simpler sugars. This lab was conducted to physically see the breakdown of carbohydrates into simpler sugars (glucose‚ fructose‚ galactose) using the salivary amylase enzyme. This is extremely important to all metabolic functions in the human digestive system. It

the soil. It consists of ground limestone which is predominantly calcium carbonate. Different soil types behave differently hence there is the need to test for acidity. To raise the pH and lower the acidity or sweeten the soil‚ lime is added. Agricultural lime or garden lime is made from pulverized limestone or chalk. Some types of garden lime are dolomite lime‚ quicklime and slaked lime. Calcium carbonate

STK 1084 Inorganic Chemistry I‚ LU 3 Oxidation – Reduction Reactions‚ Prepared By: Dr. Tay Meng Guan‚ Faculty of Resource Science and Technology‚ Universiti Malaysia Sarawak. LU 3 Oxidation and Reduction Reactions 3.1 Ideas of Oxidation and Reduction Oxidation of an atom can be occurred in the following conditions: 1. Losing an electron from the orbitals. e.g.: A A+ + e- 2. Adding an electronegative element (e.g.: F‚ Cl‚ Br‚ O) to a molecule. e.g.: A + F AF 3. Losing hydrogen

Lab report is one way we used during of after an experiment in a laboratory to subtly record and discuss the experiment. During a lab‚ we sometimes can observe only the physical part of the experiment‚ or may be some visible chemical changes. These changes indicate that the experiment we do is successful or not. However‚ in order to understand and achieve more from just simply doing the experiment‚ we write lab report to more profoundly understand the internal meanings of the experiment we do‚ and

Using Selective Media to Monitor the Fermentation Process of Cabbage and Cucumber‚ for Fourteen Days Abstract: Introduction: The goal of the ecological succession lab is to demonstrate succession with the fermentation of cabbage and cucumbers. The cabbage will ferment into sauerkraut and the cucumber will ferment to pickles during fermentation process that will changes the species structure and the community of time. During the fermentation process we watched the pH become more acidic‚ since

DEFINITIONS OF OXIDATION AND REDUCTION (REDOX) This page looks at the various definitions of oxidation and reduction (redox) in terms of the transfer of oxygen‚ hydrogen and electrons. It also explains the terms oxidising agent and reducing agent. Oxidation and reduction in terms of oxygen transfer Definitions • Oxidation is gain of oxygen. • Reduction is loss of oxygen. For example‚ in the extraction of iron from its ore: [pic] Because both reduction and oxidation are going on side-by-side
