Write the balanced chemical equations for the following reactions. (AS1)

Hydrogen + Chlorine. Hydrogen chloride

H₂ + Cl₂→ HCl

Balanced equation: H₂ + Cl₂→ 2HCl

Explanation:

⇒Step 1: Write the given unbalanced equation

H₂ + Cl₂→ HCl

⇒Step 2: Compare the number of atoms of reactants with the number of atoms of products.

⇒Step 3: Now, first we consider the element having unequal no. of atoms on both sides. First, let us consider hydrogen atom. If we multiply 2 in the product (in HCl), we will get the equal number of atoms as in reactant (H₂)

⇒Step 4: Write the resulting equation:

H₂ + O₂ 2HCl

⇒Step 5: Now check whether the equation is balanced or not by comparing the atoms

We find that the equation is now balanced yet.

⇒Step 6: Write down the final balanced equation:

2H₂ + Cl₂ 2HCl
