Mole Ratio of a Chemical Reaction: Copper & Silver Nitrate Lab #4 OBJECTIVE In this experiment‚ you will determine the number of moles of reactants and products present in the reaction of copper and silver nitrate‚ and calculate their mole-to-mole ratio. The mole-to-mole ratio relating to the disappearance of copper and the formation of silver metal will be used to write the balanced equation for the reaction. The reaction of copper metal with silver nitrate solution is a single

Redox Reactions Reactions involving oxidation and reduction processes are very important in our everyday world. They make batteries work and cause metals to corrode (or help to prevent their corrosion). They enable us to obtain heat by burning fuels--in factories and in our bodies. Many redox reactions are complex. However‚ combustion and synthesis (from elements) are two ordinary examples which require very little description. Just a little more involved are the displacement reactions‚ with

I. What is the understanding of drug use and drug abuse? A. Drug abuse is the use of illegal drugs or the misuse of prescription or over-the-counter drugs. 1. Many people use drugs in order to escape physical and emotional discomfort. 2. People who use and abuse illegal drugs are people who do not want to face life. Instead of learning how to deal with their stress and anxiety‚ they choose to try to hide by taking mind-altering substances. B. Millions of Americans also

Rates of Reaction Coursework Aim: To find out how different concentrations of sodium thiosulphate (Na S2 O3) affects the speed of its reaction with Hydrochloric acid (HCL). Introduction When Sodium Thiosulphate and Hydrochloric acid react they produce a cloudy precipitate. Both of the chemicals are clear solutions and they react together to form a yellow precipitate of sulphur‚ the equation for this reaction is: Na2 S2 O3 + HCL‚ H2 O + NaCL + SO2 + S Sodium Thiosulphate + Hydrochloric

IB Chemistry 2 Prompt -Design an experiment relating to or utilizing the concepts of stoichiometry. Background Information -Stoichiometry is the study of the quantitative relationships between reactants and products. You can calculate or predict the amount of reactants needed or product will be produced from a balanced equation with some known quantitative physical properties. Stoichiometry was first introduced to chemistry by Jeremias Benjamin Richter from Germany in the late 18th century
