A) \[52.6\]
B) \[55.1\]
C) \[44.9\]
D) \[47.4\]
Correct Answer: A
Solution :
: \[BaO+2HCl\to BaC{{l}_{2}}+{{H}_{2}}O\] \[CaO+2HCl\to CaC{{l}_{2}}+{{H}_{2}}O\] Reactions show that 2 moles of mix. of \[BaO\] and \[CaO\] requires 4 moles of \[HCl\] to react completely. Hence, no. of moles of \[HCl=\frac{2.5\times 100}{1000}\] \[=0.25moles\]Now, | HC1 | \[BaO+\text{C}aO\] |
Initial | 4 moles | 2 moles |
Final | \[0.25\]moles | ? |
