Help me pls balance equation

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

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

answer: lol

explanation:

lol

the correct option is c.

isotopes refers to different forms of the same element with the same atomic number but different mass number as a result of difference in their neutron numbers. isotopes have different relative atomic mass but share the same chemical properties.
