Calculate H for the reaction 2 C( s ) + H 2 ( g ) C 2 H 2 ( g ) Given the following chemical equations and their respective enthalpy changes:
Calculate ΔH for the reaction
2 C(s) + H2(g) → C2H2(g)
Given the following chemical equations and their respective enthalpy changes:
C2H2(g) + O2(g) → 2 CO2(g) + H2O(l) ΔH = −1299.6 kJ
C(s) + O2(g) → CO2(g) ΔH = −393.5 kJ
H2(g) + O2(g) → H2O(l) ΔH = −285.8 kJ
