Chemical reactions proceeding until all the reactants are used is a common misconception. Chemical reactions actually behave differently. The general reaction equation is a A + b B → c C +d D in this equation A and B are the reactants forming the products C and D. However‚ unlike the common thought that the reaction ends when it runs out of A and B it actually does not. In most reactions C and D start to react to form A and B at a certain point as you can see in the equation c C + d D → a A + b

Lab Report: Identifying Physical and Chemical Changes Nelson Science Perspectives 10 section 5.2 Amazing Student September 17‚ 2012 Mrs. Volkmann SNC 2D Purpose: To collect evidence and then use it to identify physical and chemical changes. Hypothesis: I predict the following: Change 1 will be a chemical change Change 2 will be a chemical change Change 3 will be a physical change Change 4 will be a chemical change Change 5 will be a chemical change Change 6 will be a physical

Shanel Warren Tiffany‚ Princess‚ and Wei October 2‚ 2013 Determining the Mole Ratios in a Chemical Reaction Introduction The purpose of this lab was to determine the mole ratios of the reactants hypochlorite ion (OCI ) and thiosulfate (S O ) when reacted in a chemical reaction. A chemical equation gives the mole ratios of the reactants and products involved in the chemical reaction. When some formulas of the products are not known‚ experimental measurements can be made to determine

World War I Chemical Warfare On April the 22‚ 1915 at the start of the Second Battle of the Ypres‚ the first poison gas attack and the first use of chlorine gas in a battlefield started‚ even though the Hague declaration and Convention forbade the use of poison weapons in the warfare. The Germans attacked France with the chlorine gas‚ but the French were not prepared at all for this attack. The effects of the chlorine gas to the soldiers was very severe; within seconds it destroyed their respiratory

Experiment: 3A The purpose of laboratory assignment 3 was to measure the rate at which a chemical reaction takes place. For the purpose of this lab we measured the rate a balanced oxidation/reduction reaction between iodine‚ hydrogen‚ and bromate ion occurs. The above reaction occurs slowly so we used a coupled iodine clock reaction to measure the rate of the oxidation/reduction reaction because it occurs much faster but is still dependent upon the other reaction. To accomplish this‚ two mixtures

2.MATERIALS and METHODS 2.1. Nature of Reactants 2.1.1 We placed 3mL of 3 M HCl into each of 3 seperate test tubes. Next we added mossy zinc to the first test tubes‚ Sn granules to the second and Cu filings to the third and compared the rates of evolution of hydrogen gas in each test tube. 2.1.2. We mixed 3mL of 0.02 M KMnO4 and 2mL of 3 M H2SO4 in a test tube and stirred using a glass rod. Next‚ we divided the solution into two. We added 2mL of 0.03 M Na2C2O4 solution to the first half and

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

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.
