Answer 1

Ответ:

2Ca + O2 → 2CaO

P2O5 + 3H2O → 2H3PO4

Na2O + H2O → 2NaOH

Mg(OH)2 + H2SO4 → MgSO4 + 2H2O

CO2 + H2O ⇄ H2CO3

2H2 + O2 → 2H2O

Al(OH)3 + 3HCl → AlCl3 + 3H2O

Ca(OH)2 + H2SO4 (разб) → CaSO4 + 2H2O

BaO + H2O → Ba(OH)2

4P + 5O2 → P4O10 (О2 в изб.)

4P + 5O2 → 2P2O5 (О2 в изб.)

4P + 3O2 → P4O6 (О2 в недостатке)

4P + 3O2 → 2P2O3 (О2 в недостатке)

4Al + 3O2 → 2Al2O3

HI + NaOH (разб) → NaI + H2O

S + O2 → SO2

SO3 + H2O → H2SO4

2Cu + O2 →(t°) 2CuO реакция протекает в условиях избытка О2 при t°≈450°C.

4Cu + O2 →(t°) 2Cu2O реакция протекает в условиях недостатка О2 при t°≈250°С.

NaOH + HCl (разб)→ NaCl + H2O

CaO + H2O → Ca(OH)2

Zn(OH)2 + 2HNO3 (разб) → Zn(NO3)2 + 2H2O

2. P2O5 + H2O → 2 H3PO4 (Balanced)

3. Na2O + H2O → 2 NaOH (Balanced)

4. Mg(OH)2 + H2SO4 → MgSO4 + 2 H2O (Balanced)

5. H2O + CO2 → H2CO3 (Balanced)

6. H2 + O2 → 2 H2O (Balanced)

7. Al(OH)3 + 3 HCl → AlCl3 + 3 H2O (Balanced)

8. Ca(OH)2 + H2SO4 → CaSO4 + 2 H2O (Balanced)

9. BaO + H2O → Ba(OH)2 (Balanced)

10. P4 + 5 O2 → 2 P2O5 (Balanced)

11. 4 Al + 3 O2 → 2 Al2O3 (Balanced)

12. HI + NaOH → NaI + H2O (Balanced)

13. 2 S + 3 O2 → 2 SO3 (Balanced)

14. H2O + SO3 → H2SO4 (Balanced)

15. 2 Cu + O2 → 2 CuO (Balanced)

16. NaOH + HCl → NaCl + H2O (Balanced)

17. CaO + H2O → Ca(OH)2 (Balanced)

18. Zn(OH)2 + 2 HNO3 → Zn(NO3)2 + 2 H2O (Balanced)
