How many chlorine atoms are on the products side of the reaction 2al + 6hcl → 2alcl3 + 3h2? 2 3 6 9

There are 6 Chlorine atoms on the products side of the reaction  2Al + 6HCl → 2AlCl₃ + 3H₂

For the reaction 2Al + 6HCl → 2AlCl₃ + 3H₂, the reactant side is at the left side of the arrow, and the product side is at the right side of the arrow.

Of the two molecules located on the product side, the one that contain chlorine (Cl) is AlCl₃.

The subscripts in a chemical formula indicate the number of atoms in a molecule, so AlCl₃ has 3 Chlorine atoms.

The coefficients in front of a substance in a chemical equation show the number of units of that substance that are involved in the chemical reaction. There are 2 units of AlCl₃ in the reaction, so the total number of Chlorine atoms is 2 units * 3 atoms = 6 atoms.

Have a nice day!
