The chemical reaction between hydrogen (H₂) and chlorine (Cl₂) to produce hydrogen chloride (HCl) can be represented by the balanced equation:
\[ \text{H}_2 + \text{Cl}_2 \rightarrow 2 \text{HCl} \]
In this reaction:
-
Reactants:
- 1 molecule of hydrogen (H₂) consists of 2 hydrogen atoms.
- 1 molecule of chlorine (Cl₂) consists of 2 chlorine atoms.
-
Products:
- The reaction produces 2 molecules of hydrogen chloride (HCl).
- Each molecule of HCl contains 1 hydrogen atom and 1 chlorine atom.
To determine the number of each type of atom in the products:
- From 2 molecules of HCl, you have:
- Hydrogen: \( 2 , \text{HCl} \times 1 , \text{H} = 2 , \text{H} \) atoms
- Chlorine: \( 2 , \text{HCl} \times 1 , \text{Cl} = 2 , \text{Cl} \) atoms
Therefore, in the products (hydrogen chloride):
- Total hydrogen atoms: 2
- Total chlorine atoms: 2
In summary, the reaction will produce 2 hydrogen chloride (HCl) molecules, containing 2 hydrogen atoms and 2 chlorine atoms.
