When 2.50 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 22.00 °C to 40.32 °C. If the specific heat of the solution is 4.18 J g^-1°C^-1, calculate ΔH for the reaction, as written. Ba(s)+ 2H₂O(l)→ Ba(OH)₂(aq)+ H₂(g)Δ_rH = ?
