Multiple-choice questions may continue on the next column or page find all choices before answering. 001 4.0 points 250.0 ml of 0.320 M copper (II) sulfate solu- tion is reacted with 100.0 ml of 1.50 M potas- sium hydroxide. The unbalanced molecular equation for this reaction is: CuSO 4 + KOH Cu(OH) 2 + K 2 SO 4 Balance the equation for this reaction and determine the limiting reagent for this reac- tion using the information given above. Then report the number of moles of Cu(OH) 2 that can be formed before the limiting reagent runs out. Answer in units of moles. 002 4.0 points Determine the limiting reactant for the fol- lowing reaction, given that 500 grams of each reactant was used. 3 Cu (s) + 2 H 2 O (l) + SO 2 (g) + 2 O 2 (g) Cu 3 (OH) 4 SO 4 (s) 1. SO 2 (g) - 2.62 moles of product formed 2. H 2 O (l) - 2.62 moles of product formed 3. O 2 (g) - 7.81 moles of product formed 4.4....
