Consider the reaction below:
cu(no3)2 + koh -> cu(oh)2 + kno3

heat energy reaction= -54.992 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?
