Question

[
A+2 mathrm{HCl} rightarrow A mathrm{Cl}_{2}+mathrm{H}_{2}
]
Mole: ( frac{x}{15} quad frac{x}{15} )
[
B+2+mathrm{ICl} rightarrow B mathrm{Cl}_{2}+mathrm{H}_{2}
]
Mole : ( frac{2-x}{30} )
( frac{2-x}{30} )
Total moles of ( mathrm{H}_{2}=frac{x}{15}+frac{2-x}{30}=frac{2.24}{22.4}=frac{1}{10} )
( Rightarrow x=1 mathrm{g} )

# 2 g mixture of two divalent metals A (at wt = 30) and B (at wt = 15) on reacting with dilute HCI solution gives 2.24 L H, gas at NTP then composition of A (in g) :- (1) 1 X 80 (2) 0.5 (3) 1.5 (4) 1.2
