35. When 75.0 grams of ammonia, 90.0 grams of carbon dioxide and 61.6 grams of water are reacted to form ammonium carbonate, what is the limiting reactant and how many grams of product will be formed?​

4.25g sample of solid ammonium nitrate dissolves in 60.0g of water in a coffee-cup calorimeter, the temperature drops from 22.0 c to 16.9 c. assume that the specific heat of the solution is the same as that of pure water. calculate delta(h) (in kj/mol nh4no3) for the solution proces.
