Determine the percent yield of copper.
3. What is the theoretical yield of copper produced by this reaction? Materials: Copper (II) chloride • Aluminum foil • Stirring rod • Two 100 ml beakers • Graduated cylinder • Safety glasses • Spatula or scoopula • Balance Filter paper front counter Funnel • Watch glass Ring stand • Iron ring Safety: Safety glasses must be worn at all times! Copper (II) chloride is an irritant and moderately toxic. Avoid inhaling the powder...

the 3 pages deal with limiting reactant and percentage yield.
the mixture starts out as a bright blue and when spinning in the
cup smokes ans starts to tirn a black color and the end result is a
brown color. then the funnel part was a light blue color.

Choose the equation that correctly represents the reaction between copper(II) sulfate and sodium hydroxide. CuSO4(aq) + 2 NaOH(aq) --> Cu(OH)2(s) + Na2SO4(aq) CuSO4(aq) + 2 NaOH(aq) --> Cu(OH)2(aq) + Na2SO4(s) CuSO3(aq) + 2 NaOH(aq) --> Cu(OH)2(s) + Na2SO3(aq) CuSO4(aq) + NaOH(aq) --> CuOH(s) + NaSO4(aq)

Objective Find the ratio of moles of reactant to moles of a product for the reaction...
Objective Find the ratio of moles of reactant to moles of a product for the reaction below. Compare mass and mole amounts of reactants to determine the amount of products that can be/are made. Background Chemical reactions are represented by balanced chemical equations. Proper interpretation of an equation provides a great deal of information about the reaction it represents and about the substances involved in the reaction. For example, the coefficients in a balanced equation indicate the number of moles...

how do you do this ?
Some Calculations You started out with a known amount of harium chloride and sodium sulfate. How much solid product should you collect? Show your calculations. How much did you collect? What is your percent yield? Which reactant should be the limiting reagent? Which reactant should be the excess reagent? Proving the identity of the Limiting and Excess Reagents There are two scenarios for the identity of the contents of the beaker containing the filtrate....
