Question

Н3РО4 + Na2O = Н3РО4 + Na2SO3 =Н3РО4 + NaOH = Na3PO4 + …2Н3РО4 + 2… = Na2HPO4 + …2Н3РО4 + … = NaH2PO4 + ...

Answer 1

Відповідь:

2Н3РО4 + 3Na2O = 2Na3PO4 + 3H2O

2Н3РО4 + 3Na2SO3 = 3H2SO3 + 2Na3PO4

Н3РО4 + 3NaOH = Na3PO4 + 3H2O

2H3PO4 + 2 NaOH = Na2HPO4 + H2O

2Н3РО4 +Na2HPO4  = NaH2PO4 + H2O

Answer 2

It seems like you're providing a series of chemical reactions involving phosphoric acid (H3PO4) and sodium compounds. I'll help you balance the equations and provide information about the reactions:

1. H3PO4 + Na2O → Na3PO4 + H2O Balanced Equation: 2H3PO4 + 3Na2O → 6Na3PO4 + 3H2O

2. H3PO4 + Na2SO3 → Na2HPO4 + NaHSO4 Balanced Equation: H3PO4 + Na2SO3 → Na2HPO4 + H2SO4

3. H3PO4 + NaOH → NaH2PO4 + H2O Balanced Equation: H3PO4 + 2NaOH → NaH2PO4 + 2H2O

4. 2H3PO4 + 2NaOH → Na2H2PO4 + 2H2O Balanced Equation: 2H3PO4 + 2NaOH → Na2H2PO4 + 2H2O

5. 2H3PO4 + Na2O → Na2HPO4 + H2O Balanced Equation: 2H3PO4 + Na2O → 2NaH2PO4 + H2O

Please note that balancing chemical equations requires adjusting the coefficients of the compounds to ensure that the same number of atoms of each element are present on both sides of the equation. Also, some of the reactions you mentioned might not be completely accurate based on standard chemical knowledge, so it's a good idea to double-check the specific reactions and their conditions if you're working on a real-world scenario.
