Question

What coefficient for the aluminum be when this equation is balanced AL+CL2->ALCL3

Answer 1

1. Coefficient of the Al is 2.
2. Coefficient of the
   `Cl_2` is 3.
3. Coefficient of the
   `AlCl_3` is 2

Step-by-step explanation:

According to Law of Conservation of Mass :In the balanced chemical reaction the mass of the reactant is equal to the mass of products

After balancing the given chemical equation:'

`2Al+3Cl_2\rightarrow 2AlCl_3`

1. Coefficient of the Al is 2.
2. Coefficient of the
   `Cl_2` is 3.
3. Coefficient of the
   `AlCl_3` is 2
