Question

Given 2CuO_(g) -> 2Cu_(s)+O_2(g) ΔH°= 314.6 kJ

a. Determine the heat of formation of CuO.

b. Calculate the standard enthalpy change for the formation of 13.58 g of CuO.

Answer 1

a) Heat of formation of CuO=$104.6 kJ$

b) Standard enthalpy change for the formation of 13.58 g of CuO. $\Delta H°=-26.86kJ$
