Consider the reaction below:
Cu(NO3)2 + KOH -> Cu(OH)2 + KNO3

Heat Energy Reaction= -54.990000000000002 kJ

-Balance the reaction, then:
1. Find what mass of KOH is consumed when 4.85 kJ of heat is absorbed.
2. The density of Cu(NO3)2 is 4.8546298500775293 g/L. What will be the mass of Cu(OH)2 produced from 35.0 mL of this solution?
3. In the reaction of 3.00 g of each reactant, what is the mass of KNO3 produced?

Please show the stoichiometry equations you set up. Thank you!!!
