1. How many moles of copper could you obtain from the decomposition of 1.00mol of CuCO3*Cu(OH)2? 2. Your calculated yiled for a particular precipitation reaction is 4.569g. After performing the experiment, you discover your actual yield is 4.354g. What is your percent recovery (percent yield) for the reaction?

The theoretical yield of 1,2-epoxycyclohexane is _grams, when starting with 3.0 grams of trans-2- bromocyclohexanol. (Enter the number using 3 significant figures, i.e. 1.22) Given: 3.0 g of trans-2-bromocyclohexanol FW: 179.05 25 mL of 10% NaOH FW: 40 and density: 1.11 g/mL 1,2-expoxycyclohexane FW: 98.15 Hint: Identify the limiting reactant (NaOH or trans-2- bromocyclohexanol) by calculating the number of moles of each. For 1 mole of limiting reactant, 1 mole of product is formed. Use the # of moles and...
