Answer:
 C₇ H₁₆ + 11O₂ → 7CO₂ + 8H₂O
Step-by-step explanation:
Given equation 
 C₇ H₁₆ + O₂ → CO₂ + H₂O
To solve this problem, 
 We use a mathematical approach to balance the equation: 
 aC₇ H₁₆ + bO₂ → cCO₂ + dH₂O
Conserving C; 7a = c 
 H ; 16a = 2d 
 O: 2b = 2c + d 
Let a = 1 
 c = 7 
 d = 8 
 b = 11 
Now insert the parameters and solve; 
 
  C₇ H₁₆ + 11O₂ → 7CO₂ + 8H₂O
