Question

Ca3(Po4)2 + Na OH; H3Po4 +CaO

Answer 1

Ответ:

Ca3(PO4)2 + 6NaOH = 2Na3PO4 + 3Ca(OH)2

3CaO + 2H3PO4 → Ca3(PO4)2 + 3H2O

Answer 2

Ответ:

Ca3(Po4)2 + 6NaOh --> 2Na3Po4 + 3Ca(Oh)2

2H2Po4 + 3Cao --> Ca3(Po4)2 + 3H2O

Answer 3

The equations you provided are chemical reactions. Let's balance them and write the balanced equations.

1. Ca₃(PO₄)₂ + NaOH → H₃PO₄ + Ca(OH)₂

In this reaction, calcium phosphate (Ca₃(PO₄)₂) reacts with sodium hydroxide (NaOH) to produce phosphoric acid (H₃PO₄) and calcium hydroxide (Ca(OH)₂).

2. H₃PO₄ + CaO → Ca₃(PO₄)₂ + H₂O

In this reaction, phosphoric acid (H₃PO₄) reacts with calcium oxide (CaO) to produce calcium phosphate (Ca₃(PO₄)₂) and water (H₂O).

Please note that these reactions are simplified and might not accurately represent the complete reaction mechanisms or stoichiometry. The balanced equations provided here are based on the given reactants and products.
