Here is a problem related to Hess's Law for the student to solve:Suppose you are given the following three equations, each with their respective enthalpy change: (1) 2H2(g) + O2(g) --> 2H2O(l) ΔH₁ = -572 kJ/mol (2) 2H2O(l) --> 2H2(g) + O2(g) ΔH₂ = 472 kJ/mol (3) C(s) + O2(g) --> CO2(g) ΔH₃ = -394 kJ/molUse Hess's law to calculate the enthalpy change (in kJ/mol) for the following reaction: C(s) + 2H2(g) --> CH4(g)
