Answer 1

Ответ:

1)Cu(OH)2+2HNO3 → Cu(NO3)2+2H2O

2)3KOH+H3PO4 → K3PO4+3H2O

3)3Ba(OH)2+2H3PO4 →Ba3(PO4)2+6H2O

4)2FeCl3+3Ba(OH)2 → 3BaCl2+2Fe(OH)3

5)Fe2O3+6HNO3 → 2Fe(NO3)3+3H2O

6)CuO+2HCl → CuCl2+H2O

7)6KOH+P2O5 → 2K3PO4+3H2O

Answer 2

I see that you have provided a list of chemical reactions with missing reactants and/or products. I'll help you balance these chemical equations by filling in the missing components:

1. Cu(OH)2 + 2HNO3 = Cu(NO3)2 + 2H2O
2. 3KOH + H3PO4 = K3PO4 + 3H2O
3. 3Ba(OH)2 + 2H3PO4 = Ba3(PO4)2 + 6H2O
4. 2FeCl3 + 3Ba(OH)2 = 3BaCl2 + 2Fe(OH)3
5. 2Fe2O3 + 6HNO3 = 3H2O + 2Fe(NO3)3
6. CuO + 2HCl = CuCl2 + H2O
7. 3KOH + P2O5 = 2K3PO4 + H2O
