Answer:
B. 10:13
Explanation:
It is clear from the following balanced equation:
- 2 C₄H₁₀ + 13 O₂ → 8 CO₂ + 10 H₂O
13 mole of oxygen (O₂) react with butane (C₄H₁₀) to give carbon dioxide (CO₂) and 10 moles of water (H₂O).
∴ The molar ratio between water and oxygen = (no. of moles of water : no. of moles of water) = (10:13)
So, the right choice is:
B. 10:13
