2C12H22011 + 1202 - 24CO2+11H20

C12H22011 + 1202 - 12C02 + 22H2O

C12H22011 + 1202 - 12002 + 11H20

Next Question

C₁₂H₂₂O₁₁ + 12O₂ → 12CO₂ + 11H₂O

Explanation:

The last equation is correctly balanced:

C₁₂H₂₂O₁₁ + 12O₂ → 12CO₂ + 11H₂O

There are twelve carbon, 22 hydrogen and 35 oxygen atoms on both side of equation.

All others equations are incorrect because,

C₁₂H₂₂O₁₁ + 12O₂ → 6CO₂ + 11H₂O

In this equation only hydrogen atoms are balanced while oxygen and carbon are not balanced.

2C₁₂H₂₂O₁₁ + 12O₂ → 24CO₂ + 11H₂O

in this equation hydrogen and oxygen atoms are not balanced only number of carbon atoms are balanced.

C₁₂H₂₂O₁₁ + 12O₂ → 12CO₂ + 22H₂O

in this equation hydrogen and oxygen atoms are not balanced only number of carbon atoms are balanced.
