Question

Write the complete balanced equation for the following reaction:

C7H14 + O2 CO2 + H2O

Answer 1

@.Sam.

Answer 2

Well first balance the carbon,
C7H14 + O2 = CO2 + H2O
C7H14 + O2 = 7CO2 + H2O
Then there's 14 hydrogen on the LHS,
So 7 for RHS
C7H14 + O2 = 7CO2 + 7H2O
To balance oxygen, there's 21 oxygens on the RHS, so we'll use half of those on the LHS since its O "2".
\[C_7H_{14} + \frac{21}{2}O_2 = 7CO_2 + 7H_2O\]
The equation is now balanced, you can multiply by 2 for both sides to eliminate fractions.
