relationship between copper and iron in a chemical reaction. The stoichiomentry of mass is that during the heating the experiment does loose mass .This mean that mole and mass did change. An Example of real world is Masses and volumes of products are extremely important in key reactions such as the deployment of air bags in vehicles‚ carbon dioxide production to help bread rise‚ and the Production of ammonia gas for industries. To do this lab we weighed Copper. Than we weighed

coating a metal object with a thin layer of another metal by means of electrolysis. 2) What is Copper Plating? Copper plating is a coating of copper metal on another material‚ often other metals. Plating is designed to increase durability‚ strength‚ or visual appeal‚ and copper plating specifically is often used to improve heat and electrical conductivity. 3) What are the uses of electro-plating/copper plating? Electroplating is used to give metal objects a better appearance or to protect them

particular metal ion. A very common hydrate often encountered in the general chemistry laboratory is copper (II) sulfate pentahydrate‚ CuSO4.5H20. The word “pentahydrate” in the name of this substance indicates that five water molecules are bound in this substance per copper sulfate formula unit. Hydrated water molecules are generally indicated in formulas as shown above for the case of the copper sulfate‚ using a dot to separate the water molecules from the formula of the salt itself. Although not usually

Scientific at scientificsonline.com Add one scoop each of luminol and perborate mixtures and a few copper sulfate crystals to each cup. Add a consistent amount of each chemical. Try to count the grains of copper sulfate so that you are adding close to the same amount to each reaction. As an option‚ premix the dry ingredients in a clean‚ dry container. Add enough luminol‚ perborate‚ and copper sulfate for 10 reactions. This will minimize variation that could result if you add them separately. Put the

Metals using different Solutions Purpose/ Hypothesis: The purpose of this lab was to clearly identify the reactivity of magnesium‚ zinc and copper. The metals reactivity will be exemplified as it will be tested with different solutions such as zinc sulfate (ZnSO4)‚ copper sulfate (CuSO4)‚ hydrochloric acid (HCL)‚ magnesium sulfate (Mg2SO4)‚ iron (II) sulfate (FeSO4) and tin (II) chloride (SnCl2). This will allow us in creating an activity series to visually see the reactivity when given single displacement
