uation is not balanced Caso AlCl3 CaCl2 Ala so 3 SO4 appea

uation is not balanced Caso, + AlCl3 CaCl2 + Ala (so, )3 SO4\" appears in two different places in this chemical equation. SO is a polyatomic ion cal at number should be placed in front of CaSO4 to give the same total number of sulfate ions o f the equation? ?Caso, +AICI CaCh + Al2 (SO,)3 ur answer numerically as an integer. ilable Hint(s) Previous Answers

Solution

CaSO₄ + AlCl₃ -----> CaCl₂ + Al₂(SO₄)₃ (Given unbalanced molecular equation)

3CaSO₄ + 2AlCl₃ ------> 3CaCl₂ + Al₂(SO₄)₃ (balanced equation)

if we look at both left side and right side,

no of each atoms

Ca=3 .........Ca= 3
SO₄=12.........SO₄= 12
Al=2.............Al= 2
Cl=6............Cl= 6

So the answer is 3 .

Thanks.
