PRE-LAB The purpose of the lab is to determine the moles of hydrogen gas and then molar mass of the metal. First‚ the metal assigned to each group must be weighed out in order to ensure the hydrogen gas produced will not exceed the capacity for the gas measuring tube. Then‚ copper will be wrapped around the metal leaving 6-8cm at the end for a handle. The end wire will be bent into a hook to keep the sample at the bottom of the tube and increase the oxidation rate. A ring stand will need to be

THE CLASSIFICATION OF CHEMICAL REACTIONS Danny Bhatt SCH3U0-G Mr. Gandhi Wednesday‚ April 1st‚ 2014 INTRODUCTION The purpose of this lab is to determine the different types of chemical reactions and differentiate between them based on similar characteristics of each set category. In this lab it is hypothesized that every chemical reaction which was observed would fall under already set categories (that are: synthesis‚ decomposition‚ single displacement‚ double displacement‚ combustion and

An important innovation of chemical advances is a material known as Hydrogels. What are Polymers and Why Use Carbon and Silicon Atoms? Polymers are repeating chains of monomers (atoms) which link in varying trends depending on their individual properties. These properties determine

A chemical reaction is a reaction that happens everywhere.It is a process which includes one or many other substances.The substances are converted in to one or more different substances.The substances are one of either chemical elements or compounds.this chemical reaction rearranges the constituent atoms of the reactions to create different substance as products. The chemical reaction of heat on alka seltzer begins when the tablet enters the water.As soon as it does the tablet starts to dissolve

Philip Morris Pakistan is beginning to feel a financial pinch‚ and is already reducing the scale and scope of some of its manufacturing operations inside the country. In a statement released to the press on Saturday‚ the company announced that it will be reducing the operations in its smallest factory‚ located in Mandra‚ near Rawalpindi. The company cited “difficult economic conditions” including high taxes and low consumer purchasing power as a primary reason for the decision. The decision was

MODULE 1: THE CHEMICAL EARTH 3.1.1: Elements in Earth are present mostly as compounds because of interactions at the atomic level * Identify that matter is made of particles that are continuously moving and interacting Matter: anything that has mass and occupies space. Exists in three different states: solid (s)‚ liquid (l) and gas (g) The Particle Theory: “All matter is made up of small‚ indivisible particles called atoms that are continuously moving” | Solid | Liquid | Gas | Particle

The purpose of the first part of the experiment was to produce a chemical compound which was the alum crystals by using aluminum‚ potassium hydroxide and sulfuric acid. After the compound was present‚ the purpose of the second part of the experiment was to make sure that the compound that was formed in the first half of the experiment was actually alum. Some of the experimental techniques that were used in this experiment was filtration using the Büchner funnel vacuum filtration‚ recrystallization

The speed of chemical reactions – class experiment By Julia Shuker Year 10 science – Miss Phillips – Term 2 – 2013 – Julia Shuker Aim The aim of the experiment was to investigate the factors that increased or decreased the speed of chemical reactions between two different chemical reactions. Hypothesis If certain factors‚ such as concentration‚ temperature‚ catalyst and surface area are increased then the reaction rate will also increase due to the particles

Chemical reactions are the basis of life on earth. As human beings‚ we are little more than the naturally abundant elements of which we are composed and the reactions between the compounds that they form. After all‚ how could life exist without water? Oxygen transport in a body the size of the human body would be impossible without the aid of a complex like hemoglobin. Besides being the basis of many of life’s intangibles‚ chemistry also plays an active role in our daily lives. Take for instance
