hydrogen chloride (hcl) dissolved in water can be used to remove rust and limescale from pipes. it is produced when hydrogen gas (h₂) and chlorine gas (cl₂) are mixed and heated. this chemical reaction is represented by the model below. determine the number of each type of atom in the reactants and products. number of atoms in reactants number of atoms in products h cl

Question

Accepted Answer

# Explanation:
## Step1: Count atoms in reactants
- For $H$: In $H_2$, there are $2$ $H$ atoms.
- For $Cl$: In $Cl_2$, there are $2$ $Cl$ atoms.

## Step2: Count atoms in products
- For $H$: In $2HCl$, there are $2$ $H$ atoms ($1\times2$).
- For $Cl$: In $2HCl$, there are $2$ $Cl$ atoms ($1\times2$).

# Answer:
|  | Number of atoms in reactants | Number of atoms in products |
|--|--|--|
| $H$ | $2$ | $2$ |
| $Cl$ | $2$ | $2$ |
