Explanation / Answer

Question 30.

balance the reaciton between:

ethane = C2H6

oxygen = O2

to form

Carbon monoxide = CO

Water vapor =? H2O

so

C2H6 + O2 = CO + H2O

balance C

C2H6 + O2 = 2CO + H2O

balance H

C2H6 + O2 = 2CO + 3H2O

balce O

C2H6 + 5/2O2 = 2CO + 3H2O

multiply all by 2

2C2H6 + 5O2 = 4CO + 6H2O

from the list, choose E
