B- 2C2H6 + 5O2 → 4CO2 + 6H2O
C- 2C2H6 + 7O2 → 4CO2 + 6H2O
D- 2C2H6 + 10O2 → 4CO2 + 6H2O

Answer:

C) 2C2H6 + 7O2 → 4CO2 + 6H2O

Explanation:

this way the number of each type of atom is balanced on each side of the equation

on the left we have:

2x2=4 C

2x6=12 H

7x2=14 O

and on the right we have:

4x1=4 C

(4x2=8)+(6x1=6)=14 O

6x2=12 H
