Answer:
Option g. (9)
Explanation:
Let's think the equation. In a combustion, the oxygen is the reactant and the products are CO₂ and water. So the reaction must be:
C₉H₈O₄ + O₂ → CO₂ + H₂O
If balance the equation would find out that the coefficient of oxygen is 9 .
C₉H₈O₄ + 9O₂ → 9CO₂ + 4H₂O
Question 1 is D. Question 2 is D. I dont want to give u the wrong answer for question 3. i havent did this in a while so thats y im stuck on 3.
