Answer:

The products are SnPO4 and LiC2H3O2

Explanation:

The reactants are LiPO4 + Sn(C2H3O2)2

This is a double replacement reaction

So what you do is switch the elements the other way around.

To do that, all you have to do switch Sn with PO4 since Sn is a cation and PO4 is an anion.

Then you switch Li with C2H3O2 because Li is a cation and C2H3O2 is an anion.

After that, check the charges. PO4 has -3 charge

So just leave Sn the way it is without a subscript.

In word form, the product would be Tin(III) Phosphate

C2H3O2 has a -1 charge Li has a +1 charge

So leave both of them the way it is without any subscripts.

In word form, the product would be Lithium Acetate
