`Br_(2(l))` reacts with `Cl_(2(g))` to from BrCl and `BrCl_(3)`, simultaneously. How many moles of `Cl_(2(g))` reacts completely with 3 moles of `Br_(2(l))` to give BrCl and `BrCl_(3)` in 5:1 mole ratio?

Answer

4

Explanation

`{:(1/2 Br_(2)(l),+1/2Cl_(2)(g), to, BrCl),((5x)/2,5/2 x ,, 5x),(1/2 Br_(2)(l),+3/2Cl_(2)(g),to,BrCl_(3)):}`
`{:((5x)/2+x/2=3,,Cl_(2)=5/2x+3/2x),(3x=3,,4x),(x=1,,4xx1=4):}`
