Type: MCQ-conceptual-Medium
The stoichiometric constants for the reaction pCu + qHNO₃ → rCu(NO₃)₂ + sNO + tH₂O p, q, r, s and t respectively are
A
3, 3, 3, 2, 3
B
3, 2, 3, 2, 4
C
3, 8, 3, 2, 4
D
2, 3, 3, 3, 2
Correct Answer
Option C
Detailed Explanation
Multiply Cu term with 3 and N term with 2: 3Cu + 2HNO₃ → 3Cu(NO₃)₂ + 2NO + H₂O. Balance H and O: 3Cu + 8HNO₃ → 3Cu(NO₃)₂ + 2NO + 4H₂O.
