When 5.50 g of is added to 100.00 g of water in a container open to the atmosphere, the reaction shown below occurs and the temperature of the resulting solution rises from 22.00°C to 61.16°C. If the specific heat of the solution is 4.18 J/(g ? °C), calculate delta H for the reaction, as written. Ba+2H2O--->Ba(OH)2+H2 Delta H?
