Question

Balance the equation __C7H6O2 + __O2 —> __CO2 + __H2O

Answer 1

2 C₇H₆O₂ + 15 O₂ → 14 CO₂ + 6 H₂O

Explanation:

C₇H₆O₂ + O₂ → CO₂ + H₂O

First we have to balance the O- atoms, we have to put 6 in front of water so there are 12 H atoms on RHS, to balance it we need to put 2 in front of  C₇H₆O₂, and so we have 14 C - atoms on LHS, 28 + 6 = 34 O - atoms on RHS, so we have to put 15 in front of Oxygen in LHS, so that each and every atom in the equation gets balanced now. The balanced equation is,  2 C₇H₆O₂ + 15 O₂ → 14 CO₂ + 6 H₂O
