Question

The following reaction shows the combustion process of ethyne:

a H₂C º CH₂(g) + b O_2(g) ® c CO_2(g)) + d H₂(g) DH = - 1300 kJ/mol

Answer 1

Although you didn't specify, I think you want to know the value of the coefficients a, b, c, d.

You must balance the reaction thusly: C2H4 + 2 O2 =====> 2 CO2 + 2 H2

a = 1 b = 2 c = 2 d = 2
