2Na + Cl₂ → 2NaCl

Answer 2

Balancing Chemical Equations

To balance the chemical equation provided, we need to ensure that the number of atoms of each element is the same on both sides of the equation. Let's balance the given chemical equation step by step.

The unbalanced chemical equation is: H₂ + O₂ + Be + Cl₂ + Cu + O₂ → Al + O₂ → Al + Cl₂ + Na + Cl₂ →

Balancing the Equation Step by Step

1. Balancing the hydrogen (H) atoms: - There are 2 hydrogen atoms on the left side and 2 hydrogen atoms on the right side. Hydrogen is already balanced.

2. Balancing the oxygen (O) atoms: - There are 4 oxygen atoms on the left side and 3 oxygen atoms on the right side. We need to add another O₂ molecule to the right side to balance the oxygen atoms. - The equation becomes: H₂ + O₂ + Be + Cl₂ + Cu + O₂ → Al + O₂ + O₂ → Al + Cl₂ + Na + Cl₂

3. Balancing the other elements: - Now, let's balance the other elements in the equation.

Final Balanced Equation

The balanced chemical equation is: H₂ + O₂ + Be + Cl₂ + Cu + O₂ → 2Al + 3O₂ → 2Al + Cl₂ + 2Na + Cl₂

This balanced equation ensures that the number of atoms of each element is the same on both sides of the equation.
