Make up the equation of the reaction: 1) calcium chloride + sodium phosphate → calcium phosphate

Make up the equation of the reaction: 1) calcium chloride + sodium phosphate → calcium phosphate + sodium chloride; 2) iron (II) hydroxide → iron (II) oxide + water; 3) sulfur oxide (VI) + water → sulfuric acid; 4) zinc + nitric acid → zinc nitrate + hydrogen. – Write down the equations of these reactions, – arrange the oxidation states (simple “0”), – add the indices, – indicate the types of chemical reactions, – arrange the coefficients.

1) Ion exchange reaction:

3Ca + 2Cl2- + 2Na3 + P + 5O4-2 = Ca3 + 2 (P + 5O4-2) 2 + 6Na + Cl-;

2) decomposition reaction:

Fe + 2 (O-2H +) 2 = Fe + 2O-2 + H2 + O-2;

3) the reaction of the connection:

S + 6O3-2 + H2 + O-2 = H2 + S + 6O4-2;

4) substitution reaction:

Zn0 + 2H + N + 5O3-2 = Zn + 2 (N + 5O3-2) 2 + H20 ↑.
