Identify the balanced chemical equation that represents a combustion reaction. 2C 4H 10 + 13O 2 ⟶ 10H 2O + 8CO 2 C 4H 10 + 5O 2
⟶ 5H 2O + 4CO 2 CaCO 2 ⟶ Ca + CO 2 2CaCO 2 ⟶ 2Ca + CO 2
1 answer:
Answer:
2C₄H₁₀ + 13O₂ ⟶ 10H₂O + 8CO₂
Explanation:
2C₄H₁₀ + 13O₂ ⟶ 10H₂O + 8CO₂ . . . . . balanced combustion reaction
C₄H₁₀ + 5O₂ ⟶ 5H₂O + 4CO₂ . . . . not balanced
The two reactions involving Ca are not combustion reactions.
