Two water solutions have a density of 1.00 g/mL are mixed and a reaction occurs. The temperature riss from 25 degree celsis to 27 degree celsius. Given that the heat capacity is 4.18J and that the total of mass of the water is 75.0g, what is the heat change for the reaction
6.27J 314J 125J 627J
2NO(g) + H2 (g) ---> (g) + H20(g) + 351 kJ
