Answer 2

The chemical equations you provided are not balanced. Here are the balanced equations for the reactions you mentioned:

1. Cu + O2 -> CuO (Copper reacts with oxygen to form copper(II) oxide)

2. AI + CI2 -> AICl3 (Aluminum reacts with chlorine to form aluminum chloride)

3. Na + CI2 -> NaCl (Sodium reacts with chlorine to form sodium chloride)

4. Be + CI2 -> BeCl2 (Beryllium reacts with chlorine to form beryllium chloride)

Please note that the subscript numbers indicate the stoichiometric coefficients required to balance the equation, ensuring that the number of atoms on both sides of the equation is equal.
