Answer:
The balanced reaction is this:
2 C₄H₁₀ (g) + 13 O₂(g) → 8 CO₂(g) + 10 H₂O (g)
Explanation:
Combustion is a chemical reaction whose reagents are oxygen, usually in excess and a hydrocarbon to generate carbon dioxide and water in the form of steam, as products.
Butane is considered as a reactant and it is a sort of alkane, in this case with 4 C (prefix but).
O₂ is needed for the complete combustion of butane.
