Chemical Warfare Final Draft Do you think it’s right to use chemical toxins to harm or kill people who are defending‚ or fighting for their lives? I don’t and that is why I am aganist chemical warfare. There are other ways which can be used to defend your country without taking away the lives of many people in such a barbaric fashion. Chemical warfare takels many innocent lives even when they haven’t done anything wrong! Chemical warfare is a way of torturing people with nerve‚ blister‚ and choking

But Manganese can ruin our bodies to; if we inhale Manganese we could have a chance of getting Parkinson disease. It is not good or bad but I don’t suggest inhaling or eating Manganese. Manganese came from the Latin word magnes. The credited founder was Johan Gottlieb Gahn a Swedish scientist. It can mostly

Biology Lab #1: Chemical Diffusion Purpose To discover how the size of a cell affects the diffusion of chemicals throughout the cell. Hypothesis I predict that as the cell size increases the diffusion depth and the diffusion rate will decrease. Equipment • Eye protection • 250 mL beaker • Timing device • Scoopula • Ruler • Scalpel • Sodium hydroxide solution • 3 different sized cubes of phenolphthalein agar • Paper towels Purpose

EXPERIMENT 1: CHEMICAL REACTIONS I. INTRODUCTION – OBJECTIVES In this first experiment‚ we will perform 8 chemical reactions and 1 flame test in order to determine 2 things : a) firstly‚ we can know whether a reaction occurred or not. To complete our mission‚ we need to observe carefully some signs of chemical reaction’s appearance such as the change in color of solution‚ precipitate’s existence‚ the release of gas‚ also check the change of heat and light. b) secondly‚ we need to have knowledge

Observations and Chemical Changes By: Andre the Giant Higgson 02/19/14 CHE 107 E1 Intro to Chemistry 1 Objective Certain Chemicals like Bromthymol blue and Phenolphthalein can be added to other chemicals to determine acidity or basicity. Other reactions can be observed as well when different chemicals are added to each other. Procedure This experiment involved placing drops of specified chemicals into a well on a 96well plate. Each well number was recorded along with question number and name of chemicals involved

broken down from complex insoluble substances into simple soluble substances. There are two types of digestion – chemical digestion and mechanical digestion. Mechanical digestion involves breaking up large pieces of food into smaller pieces. This provides a large surface area for the action of enzymes on food. There is no change to the chemical composition of food during mechanical digestion. Mechanical digestion occurs in the mouth (mastication) and in the stomach (churning). Chemical digestion involves
