Question

H2CO3 + KOH = HCl + NaOH = H3PO4 + Fe(OH)3 = H2SO4 + Ca(OH)2 = H2SiO3 + 2 NaOH =

Answer 1

Объяснение:

1) KHCO3

2) H2O + NaCl

3) FePO4+3H2O

4) CaSO4 +2H2O

5) Na2SiO3 + 2H2O

Answer 2

Let's balance the chemical equations one by one:

1. H2CO3 + 2 KOH → 2 H2O + K2CO3

2. HCl + NaOH → NaCl + H2O

3. H3PO4 + 3 Fe(OH)3 → 3 FePO4 + 3 H2O

4. H2SO4 + Ca(OH)2 → CaSO4 + 2 H2O

5. H2SiO3 + 2 NaOH → Na2SiO3 + 2 H2O

Now, the equations are balanced. If you have any further questions or need more assistance, feel free to ask!
