Which statement best describes the flow of energy in this scenario

Consider the four elements above. which one of these elements will combine with oxygen in a 1: 1 ratio?

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.
