Enthalpy and Hess's Law
Chemistry Lab Manual 2nd Edition
3) When 1.50 g of Ba(s) 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 22.00C
to 33.10°C. If the specific heat of the solution is 4.18 J/(g. °C) , calculate AH for the reaction, as
written.
Ba(s) + 2 H2O()
AH ?
Ba(OH)2(aq) + H2(g)
