What would it be if you translated this chemical symbol into a word equation?

MgCl(aq) K3PO4(aq) > Mg3(PO4)2(s) KCl(aq)

Do you know the names of each of the compounds mentioned in the equation?

I think you are missing some addition symbols.. I would think it would be: Magnesium Chloride (MgCl) + Potassium Phosphate (K3PO4) produces Magnesium Phosphate + Potassium Chloride. It is a double replacement reaction. Hope this helps :)
