3. H₂SO₄ + 2KOH ----> K₂SO₄ + 2H₂O
4. K₂CO₃ + 2HCl ---> 2KCl + H₂O + CO₂
5. CaCO₃ + 2HNO₃ ---> Ca(NO₃)₂ + H₂O + CO₂
6. Ca + 2H₂O ---> Ca(OH)₂ + H₂
7. Pb(NO₃)₂ + 2NaI ---> PbI₂ + 2NaNO₃
8. Al₂(SO₄)₃ + 6NaOH ---> 2Al(OH)₃ + 3Na₂SO₄
9. Al(OH)₃ + NaOH ---> NaAlO₂ + 2H₂O
10. 2Pb(NO₃)₂ ---> 2PbO + 4NO₂ + O₂
Explanation:
A balanced equation of a chemical reaction is one that has the number of moles of atoms of each element taking part in the reaction equal on both sides of the reaction, that is on the reactants and products sides of the reaction.
The balanced equations of the given reactions is as follows:
1. 2N₂ + O₂ ---> 2N₂O
2. BaCl₂ + 2NaOH ---> Ba(OH)₂ + 2NaCl
3. H₂SO₄ + 2KOH ----> K₂SO₄ + 2H₂O
4. K₂CO₃ + 2HCl ---> 2KCl + H₂O + CO₂
5. CaCO₃ + 2HNO₃ ---> Ca(NO₃)₂ + H₂O + CO₂
6. Ca + 2H₂O ---> Ca(OH)₂ + H₂
7. Pb(NO₃)₂ + 2NaI ---> PbI₂ + 2NaNO₃
8. Al₂(SO₄)₃ + 6NaOH ---> 2Al(OH)₃ + 3Na₂SO₄
9. Al(OH)₃ + NaOH ---> NaAlO₂ + 2H₂O
10. 2Pb(NO₃)₂ ---> 2PbO + 4NO₂ + O₂
