In a certain chemical reaction Compound A combines with Compound B to produce Compound C (and no other products). Measurements were taken of the amounts of A and B present before and after a reaction that produced some C: Compound initial amount final amount A 7.5g 0g B 3.5g 2.2g Calculate the theoretical yield of C. Round your answer to the nearest 0.1g. Suppose the percent yield of C in this reaction was 64.%. Calculate the actual amount of C that was isolated at the end of the reaction. Round your answer to the nearest 0.1g.

Predict the reactants of this chemical reaction. that is, fill in the left side of the chemical equation. be sure the equation you submit is balanced. (you can edit both sides of the equation to balance it, if you need to.) note: you are writing the molecular, and not the net ionic equation. > cacl2(aq) + h20(l)
