The experiment was taking copper II chloride, diluting it with
deionized water, heating it, and adding a metal rod so copper could
form on it. I just need help with 3 and 4.
2. What observable evidence from the experiment do you have that shows that copper (II) chloride is, indeed, the limiting reactant? 3. Error Analysis. If in Step 9, some of the solid copper was lost and was not recovered, would this increase or decrease the percent yield?...

A student started with 1.409 grams of copper (II) oxide and produced 3.500 g of copper (II) sulfate. What is the percent yield? The product is a hydrate. Use appropriate significant figures. Do not put a percent sign in the answer box. Please ignore extra zeros that will be automatically added to your answer by the system. Useful information: chemical equation: CuO(s) + H2SO4 (aq) ---> CuSO4 (aq) +H2O(l) Formula weight of hydrated copper (II) sulfate = 249.677 g/mol Formula...

Consider the following experimental error. When measuring out the reactants, some copper II chloride was spilled on the balance and was not added to the reaction flask. How would this error affect your percent yield of Cu? A) The mass that was spilled on the balance was not able to react and will not affect the percent yield. B) The total recorded mass of the copper II chloride was not able to react which will cause a low percent yield...

For the experiment I started with 3.79g of benzyltriphenyl phosphonium chloride and ended up with 1.624g. What is my theoretical and percent yield? Molecular weight of benzyltriphenyl phosphonium chloride: 388.875 g/mol. Density: 1.18 g/cm^3 No chemical reaction given. Please tell me exactly what you need to figure out the answer. Experiment was "Preparation of (Z)- and (E)-stilbenes by a Wittig Reaction"

Practice 1. An aluminum wire is placed in 60.0 mL of an unknown copper(II) chloride dihydrate solution. The copper(II) and aluminum react in the redox reaction below, producing solid copper: 3 Cu (aq) 2 Al(s) -3 Cus) 2 Al (aq) The solid copper was filtered using a Büchner funnel, and then was dried one time and weighed to be 0.256 g. It was dried a second time and weighed to be 0.235 g. It was dried a third time and...
