Combustion of hydrocarbons such as pentane (C5H12) produces carbon dioxide, a "greenhouse gas." Greenhouse gases in the Earth's
zhuklara [117]

2 C₅H₁₀ (l) + 15 O₂ (g) → 10 CO₂ (g) + 10 H₂O (g)

Explanation:

Balanced chemical equation for combustion of pentane C₅H₁₀:

C₅H₁₀ (l) + (15/2) O₂ (g) → 5 CO₂ (g) + 5 H₂O (g)

to get integer numbers for the stoechiometric coefficients we multiply with 2:

2 C₅H₁₀ (l) + 15 O₂ (g) → 10 CO₂ (g) + 10 H₂O (g)

where:

(l) - liquid

(g) - gas
