Question

1)H3PO4+AgNO3—2)H2SO4+AgNO3—3)NaPO4+H2O—4)Ca3(PO4)2+H2O—

Answer 1

H3PO4 + 3 AgNO3 → Ag3PO4 + 3 HNO3

H2SO4 + 2 AgNO3 → 2 HNO3 + Ag2SO4

NaPO4 + H2O = H3PO4+NaOH

Ca3(PO4)2 + 3 H2O → 3 CaO + 2 H3PO4

Answer 2

Here are the balanced chemical equations for the given reactions:

1. H3PO4 + AgNO3 → Ag3PO4 + HNO3 Phosphoric acid reacts with silver nitrate to form silver phosphate and nitric acid.

2. H2SO4 + AgNO3 → Ag2SO4 + HNO3 Sulfuric acid reacts with silver nitrate to form silver sulfate and nitric acid.

3. NaPO4 + H2O → NaOH + H3PO4 Sodium phosphate reacts with water to form sodium hydroxide and phosphoric acid.

4. Ca3(PO4)2 + 3H2O → 2H3PO4 + 3Ca(OH)2 Calcium phosphate reacts with water to form phosphoric acid and calcium hydroxide.

Please note that these balanced equations represent the stoichiometric proportions of the reactants and products.
