Answer 1

Answer:

1 . ca(oH)2

2. al2o3 + h2o

3. pbo + no2 + o2

4. Cu + FeSo4

5. nh4cl + h2o

6. kcl + o2

7. Fe3o4+H2.

8. CaO( s ) + CO2( g )

9. co + h2

Answer 2

Answer :

1. CaO + H₂O → Ca(OH)₂

• Ca(OH)₂ : Calcium hydroxid$e$

2. 2Al(OH)₃ + ∆ → Al₂O₃ + 3H₂O

• Al₂O₃ : Aluminium oxide

3. 2Pb(NO₃)₂ → 2PbO + 4NO₂ + O₂

• PbO : Lead monoxide
• NO₂ : Nitrogen dioxide

4. CaSO₄ + Fe → FeSO₄ + Ca

• FeSO₄ : Ferrous sulphate

5. NH₄OH + HCl → NH₄Cl + H₂O

• NH₄Cl : Ammonium chloride

6. 2KClO₃ + ∆ → 2KCl + 3O₂

• Catalyst : MnO₂
• KCl : Potassium chloride

7. 3Fe + 4H₂O → Fe₃O₄ + 4H₂

• Fe₃O₄ : Iron (II, III) oxide

8. NH₄Cl + ∆ → NH₃ + HCl

• NH₃ : Ammonia
• HCl : Hydrogen chloride

9. CaCO₃ + ∆ → CaO + CO₂

• CaO : Calcium oxide

10. C + H₂O → CO + H₂

• CO : Carbon monoxide
• H₂ : Dihydrogen gas
• (CO + H₂) : Water gas / Syn gas
