NA+CL-NACL

Answer 2

The given equations represent chemical reactions between different elements and compounds. To determine the products of these reactions, we need to consider the valency and charges of the elements involved. Here are the products for each reaction:

1. Be + Cl₂ (not CI²) → BeCl₂ The reaction between beryllium (Be) and chlorine (Cl₂) forms beryllium chloride (BeCl₂).

2. Cu + O₂ → CuO The reaction between copper (Cu) and oxygen (O₂) forms copper oxide (CuO).

3. Al + O₂ → Al₂O₃ The reaction between aluminum (Al) and oxygen (O₂) forms aluminum oxide (Al₂O₃).

4. Al + Cl₂ (not CI²) → AlCl₃ The reaction between aluminum (Al) and chlorine (Cl₂) forms aluminum chloride (AlCl₃).

5. Na + Cl₂ (not CI²) → NaCl The reaction between sodium (Na) and chlorine (Cl₂) forms sodium chloride (NaCl).

Please note that the symbols for chlorine (Cl) and oxygen (O) were corrected in the equations provided.
