Solve the following numerical problem: [3] Ethane burns in oxygen according to the chemical equation :
2 C 2 H 6 + 7 O 2 → 4 CO 2 + 6 H 2 O
If80 ml 300 ml
If
Solution:
Given: 2 C 2 H 6 + 7 O 2 → 4 CO 2 + 6 H 2 O
∵ 2 H 2 O + 4
2 ml 7 ml 4 ml + ml H 2 O
∴ 80 ml 280 ml = 160 ml CO 2 + 240 ml H 2 O
In this reaction ethane in the limiting reagent and20 ml
The composition of the resultant gaseous mixture when measured at room temperature will be:
20 ml 160 ml CO 2 240 ml H 2 O
In this reaction ethane in the limiting reagent and
The composition of the resultant gaseous mixture when measured at room temperature will be:
