Question

In the following decomposition reaction, identify the p, q, and r values: p FeSO4 (s) → q Fe2O3 (s) + r SO2 (g) + s SO3 (g)?

• A. 1, 1, 1, 2
• B. 1, 1, 2, 1
• C. 1, 2, 1,1
• D. 2, 1, 1, 1

Answer 1

Answer:

D. 2, 1, 1, 1

The balanced reaction is: 2 FeSO4 (s) → Fe2O3 (s) + SO2 (g) + SO3 (g) Values of p, q, r, and s: p = 2 q = 1 r = 1 s = 1
