#2. Balance the redox equation for the reaction of Cu and HNO3 giving NO2 directly.
#3. Copper dissolves in nitric acid, producing copper (ll) nitrate.
After reaction with sodium hydroxide and heating, copper nitrate changes to copper (ll)
Calculate the percent yield of this process if 1.235 g of copper produced 1.235 g of
copper oxide. Show your calculations.
