A 50.00 g sample of an unknown metal is heated at 45.00°C. It is then placed in a coffee-cup calorimeter filled with water. The calorimeter and the water have combined mass of 250.0•°g an and overall specific heat of 1.035 cal/g•°C. The initial temperature of calorimeter is 10.00°C. The system reaches a final temperature of 11.08°C when the metal is added.

the reaction mixture contains some ammonia, plus a lot of unreacted nitrogen and hydrogen. the mixture is cooled and compressed, causing the ammonia gas to condense into a liquid. the liquefied ammonia is separated and removed. the unreacted nitrogen and hydrogen are then recycled back into the reactor .

i have no clue hope you find the answer
