25 " mL of " a mixture of Co, `CO_(2)` and `H_(2)` were exploded mL with 10 " mL of " oxygen. The products has a volume of 18.5 " mL of " which 17 mL absorbed by alkali. What was the composition of the original mixture? All volume measurements were made at the same temperature and pressure?

Explanation

To solve the problem, we need to determine the composition of a mixture of carbon monoxide (CO), carbon dioxide (CO₂), and hydrogen (H₂) that was exploded with oxygen. Here’s a step-by-step breakdown of the solution:

### Step 1: Define Variables
Let:
- \( V_1 \) = volume of CO
- \( V_2 \) = volume of CO₂
- \( V_3 \) = volume of H₂
