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

Investigating Chemical Equilibrium Date: 30th April 2013 Due Date: 15th May 2013 Prepared For: M. Seraji Prepared by: Andrea Odunze Abstract Many reactions proceed to a state of equilibrium. A chemical reaction at equilibrium‚ where the rates of the forward reaction and reverse reaction are equal‚ looks like this: A + B AB There are three factors‚ according to Le Chatelier’s principle‚ that affect the equilibrium position and equilibrium constant. These are the concentrations of products

On the other hand‚ imagine how taken aback people are to find themselves dependent on chemical substances when there were no apparent clues suggesting they might be susceptible to active addiction. This sometimes happens when a person is prescribed pain pills after surgery or for pain management or a person decides to experiment with heroin‚ and the obsessions/compulsions of addiction raise their monstrous heads without warning. There is no pre-emptive strategy for this. So‚ sometimes people

Introduction The purpose of this lab is to be able to observe the reaction rates of different chemical substances‚ by looking at which substance is the fastest reactant. This is what chemical kinetics is. Reaction rate is the change in the concentration of a reactant or product in a chemical reaction per unit time. In this lab the requirement was to be able to calculate each Average reaction rate which is the change in reactant or product concentration at a given time interval. Some equations that
