Answer 1

Объяснение:

1)6Ca(OH)2+H3PO4=2Ca3(PO4)2+6H2O

Answer 2

Pairs of Substances that React with Each Other:

1. Calcium hydroxide and phosphoric acid: Calcium hydroxide (Ca(OH)2) and phosphoric acid (H3PO4) can react to form calcium phosphate (Ca3(PO4)2) and water (H2O) [[1]].

2. Zinc hydroxide and calcium oxide: Zinc hydroxide (Zn(OH)2) and calcium oxide (CaO) can react to form zinc oxide (ZnO) and calcium hydroxide (Ca(OH)2) [[2]].

3. Calcium oxide and phosphoric acid: Calcium oxide (CaO) and phosphoric acid (H3PO4) can react to form calcium phosphate (Ca3(PO4)2) and water (H2O) [[3]].

4. Zinc hydroxide and carbon dioxide (IV) oxide: Zinc hydroxide (Zn(OH)2) and carbon dioxide (IV) oxide (CO2) can react to form zinc carbonate (ZnCO3) and water (H2O) [[4]].

5. Carbon dioxide (IV) oxide and calcium hydroxide: Carbon dioxide (IV) oxide (CO2) and calcium hydroxide (Ca(OH)2) can react to form calcium carbonate (CaCO3) and water (H2O) [[5]].

Please note that these reactions are based on the provided substances and their chemical formulas. The actual reaction conditions, such as temperature and concentration, may affect the reaction outcomes.
