Answer to Question #317694 in General Chemistry for Uwhxhdjis

Question

Calculate ∆H for the reaction 2C(s) + H2(g) → C2H2(g) using the following data:

H_2(g) +1/2 O_(2(g))→H_2 O_((l)) ∆H=-286 kJ

C_((s))+O_(2(g))→〖CO〗_(2(g)) ∆H=-394 kJ

C_2 H_2(g) +5/2 O_(2(g))→2〖CO〗_(2(g))+H_2 O_((l)) ∆H=-1 300 kJ
