Use the equations in the table to calculate the enthalpy for the reaction: C(s) + 2 H2(g) → CH4(g)

Reaction ∆H° (kJ/mol)
C(s) + O2(g) → CO2(g) -393.5
H2(g) + 1/2 O2(g) → H2O(g) -285.8
CH4(g) + 2 O2(g) →
CO2(g) + 2H2O(l) -890.4

The answer is either
211.1 Kj/mol
890.4 kJ/mol
-1855.5kJ/mol
-1569.7kJ/mol
-1569.7kJ/mol
-74.7 kJ/mol

explanation:

2b2t

while cooking a piece of 1/2 pound beef steak, a cast iron pan (2.4kg in weight) was heated 260 celsius.

a gas, having a molecular weight of 13 kg/kmol and a kinematic viscosity of 0.25 cm2/s, flows through a pipe 0.25 m internal diameter and 5 km long at the rate of 0.4 m3/s and is delivered at atmospheric pressure.
