Write a balanced equation for each reaction
Al + Cl2 -->
2Al + 3Cl2 ==> 2AlCl3
To write a balanced equation for the reaction between aluminum (Al) and chlorine gas (Cl2), we need to ensure that both sides of the equation have an equal number of atoms for each element.
The reaction is as follows:
Al + Cl2 -> AlCl3
To balance the equation, we need to make sure that the number of atoms of each element is the same on both sides. In this case, we have one aluminum atom on the left side but three chlorine atoms on the right side.
To balance the chlorines, we need to place a coefficient of 3 in front of the AlCl3 compound:
Al + 3Cl2 -> 2AlCl3
Now, we have two aluminum atoms on both sides of the equation, as well as six chlorine atoms.
Therefore, the balanced equation is:
2Al + 3Cl2 -> 2AlCl3
