Rate of reaction Design Lab Background: Reaction rate is most commonly defined as the speed at which a reaction takes place. This rate can be altered by many factors such as temperature‚ pressure‚ concentration‚ volume‚ or the use of a catalyst. In order for a reaction to occur‚ the atoms must collide in the correct orientation to break the bonds and must also have more energy than the needed activation energy. If their energy is not high enough‚ the reaction will not be able to take place. By

Vanessa Gale Formal Lab: Evaluation of the Gas Law Constant Dr. Monzyk Due 06/25/2012 Purpose: The purpose of this lab is to evaluate the gas law constant. The ideal gas law is represented as PV=nRT‚ where R represents the gas law constant. To determine R‚ we must find the other parameters‚ P‚ V‚ n and T through the experiment. Equipment and Materials: Large beaker Ring stand Clamp Copper wire 100 mL eudiometer tube Magnesium (Mg) ribbon M6 H2SO4 (Sulfuric Acid) Wash bottle

Gas Exchange in Mammals The mammalian respiratory system consists of the nasal cavity‚ pharynx‚ glottis‚ larynx‚ trachea‚ bronchi‚ bronchioles and air sacs (alveoli). The respiratory passages are lined by the presence of cilia and mucus-secreting cells‚ which keep them moist and trap dust‚ dirt and bacteria. The lungs are encased a rib cage. The rib cage is composed of the breastbone or sternum and ribs. At the bottom of the rib cage is a muscular diaphragm. Breathing in mammals. During inhalation

How Much Gas is Produced? Julie Dang June 23‚ 2013 Purpose The Company ABC Chemical has asked our group to investigate the gas production from a number of various chemical reactions. The company would like us to measure the amount of product we get when we measure the amount of gas from two reactions. We will then compare our data to the predicted amount which will we will calculate based of the Law of conservation of Mass and Ideal Gas Laws. Methods Materials Thermometer CaCO3

Research on gas masks I researched gas masks. I found out about: The history Gas masks were issued to all British civilians at the start of World War 2. In Britain fear was around because the British government thought that the Nazi German bombers would drop poison gas bombs. At the start of the war some citizens had not been issued with a gas mask. In a government document "If war should come" the explanation for this was that district leaders might have decided to keep gas masks in storage
