Answer:
C₁₂H₂₂O₁₁ + 12O₂ → 12CO₂ + 11H₂O
Step-by-step 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.
