ANSWER
[tex]\text{ 2K}_3PO_4\text{ + 3SnCl}_2\text{ }\rightarrow\text{ 6KCl + Sn}_3(PO_4)_2[/tex]EXPLANATION
Given that;
Potassium phosphate + Tin (II) chlorate ----->
Firstly, write the molecular formula of each compound
[tex]\begin{gathered} \text{ Potassium phosphate = K}_3PO_4 \\ \text{ Tin \lparen II\rparen Chlorate = SnCl}_2 \end{gathered}[/tex]Write a balanced equation for the reaction
[tex]\text{ 2K}_3PO_{4(aq)}\text{ + 3SnCl}_{2(aq)}\text{ }\rightarrow\text{ 6KCl}_{(aq)}\text{ + Sn}_3(PO_4)_{2(aq)}[/tex]
