1) AlCl_(3)-Nasquare NaCl+Al

This question involves a chemical reaction and requires balancing the chemical equation. The equation provided is: The symbol '□' indicates a missing component or number in the equation. Balancing a chemical equation involves ensuring that the number of atoms of each element is the same on both sides of the equation. 1. The original equation has aluminum (Al) and chlorine (Cl) on both sides, but the sodium (Na) appears to be unbalanced. 2. Aluminum and chlorine are already balanced with one aluminum atom and three chlorine atoms on both sides.3. The sodium (Na) is present as NaCl on the right side. Therefore, to balance the sodium, we need to add a coefficient in front of NaCl and Na on the left side.The missing component is the coefficient for sodium (Na), which will balance the sodium atoms on both sides of the equation. We need 3 sodium atoms on both sides to balance with the 3 chlorine atoms in AlCl3 and NaCl. So, the coefficient in front of Na and NaCl should be 3.The balanced equation is:
