Having a hard time. Balanced equation for reaction help

Question

1) Aqueous solution of calcium chloride and sodium phosphate react to form solid calcium phosphate and aqueous sodium chloride

Balanced equation, type of reaction, and state of matter

2) Soild iron and aqueous copper (II) bromide react to form soild copper and aqueous iron (II) bromide

Balanced equation, type of reaction, and state of matter

Answer 1

1) This is a double displacement reaction.

3 CaCl₂ (aq) + 2 Na₃PO₄ (aq) → Ca₃(PO₄)₂ (s) + 6 NaCl (aq)

2) This is a single displacement reaction.

Fe (s) + CuBr₂ (aq) → Cu (s) + FeBr₂ (aq)
