Question

Write out the skeleton equation, then balance and classify the equation.Barium sulfate + aluminum phosphate barium phosphate + aluminum sulfate

Answer 1

We have the next equation

Barium sulfate + aluminum phosphate barium phosphate + aluminum sulfate

1. We must write the skeleton equation

To write the skeleton equation we must use the next

Barium sulfate: BaSO4

aluminum phosphate: AlPO4

barium phosphate: Ba3(PO4)2

aluminum sulfate: Al2(SO4)3

Then, the skeleton equation would be

BaSO4 + AlPO4 Ba3(PO4)2 + Al2(SO4)3

2. We must balance the equation

So, if we need the same number of atoms of each type pn both sides of the equation, the balanced equations would be

3BaSO4 + 2AlPO4 Ba3(PO4)2 + Al2(SO4)3
