Q.
The volume of hydrogen at STP required to reduce 7.95 grams of cupric oxide to metal is
A.
1.12lit
B.
11.2lit
C.
0.224lit
D.
2.24lit
E.
None of the above
View Answer
Correct choice: D
Explanation:
Cupric oxide is reduced to copper on treating with hydrogen
CuO + H
2
→ Cu + H
2
O
1 mole of CuO requires 1 mole of H
2
79.5 grams of CuO requires 22.4 L of H
2
at STP
7.95 grams of CuO requires ( 7.95 × 22.4/79.5) = 2.24 L of hydrogen required at STP
