Calculate the enthalpy of reaction for the following reaction. Type the number only and use significant figures. CaO(s) + H2O(l) + Ca(OH)2(s)

∆H∘f Ca(OH)2(s) = -986.6 kJ/mol
∆H∘f CaO(s) = -635.5 kJ/mol
∆H∘f H2O(l) = -285.8 kJ/mol

the formula for the conversion of temperature from degree celsius to kelvin is:

the sample of water at is converted to kelvin temperature by using the above formula as:

on comparing the two samples of water at or we can say that at and at respectively. the difference between the temperatures of two samples of water is:

hence, one can say that the sample of water at is greater than the sample of water at by .
