Explicación
The given chemical equation is:
To balance the equation, we need to ensure that the number of atoms of each element is the same on both sides of the equation.1. Aluminum (Al) is already balanced with 1 atom on both sides.2. Hydrogen (H) has 1 atom on the left side and 2 atoms on the right side. To balance hydrogen, we need to have 2 molecules of HCl on the left side, which gives us 2 hydrogen atoms on the left side.3. Chlorine (Cl) has 1 atom on the left side and 3 atoms on the right side. To balance chlorine, we need to have 3 molecules of HCl on the left side, which gives us 3 chlorine atoms on the left side.After balancing the atoms, the balanced chemical equation is:
This equation shows that 1 atom of aluminum reacts with 3 molecules of hydrochloric acid to produce 1 molecule of aluminum chloride and 3 molecules of hydrogen gas. The coefficients are 1 for Al, 3 for HCl, 1 for AlCl3, and 3 for H2, which means that the equation is balanced with the same number of each type of atom on both sides of the arrow.
