The balanced equation for the following chemical reaction – Hydrogen + Chlorine → Hydrogen chloride is H2 + Cl2 → 2HCl. A chemical reaction that has the same amount of atoms of each element on the reactant and product sides is known as a balanced chemical equation. The balanced equation for the reaction between hydrogen and chlorine to form hydrogen chloride (HCl) can be determined by calculating the number of atoms.

Balancing a Chemical Equation
When the total number of atoms of each type on both sides of the chemical equation is equal, the chemical equation is said to be balanced. In other words, there must be an equal amount of atoms on either side of the equation. Understanding the several states in which chemical compounds might exist is also important.
Solution:
To balance the chemical equation for the reaction between hydrogen and chlorine to form hydrogen chloride, follow these steps:
Step 1: Count the number of atoms of each element on both sides of the equation.
Left side (Reactants):
Hydrogen (H): 2
Chlorine (Cl): 2
Right side (Products):
Hydrogen (H): 1
Chlorine (Cl): 1
Step 2: Start balancing the equation by adjusting the coefficients in front of the molecules or compounds.
Let’s balance hydrogen first:
Left side (Reactants):
Hydrogen (H): 2
Right side (Products):
Hydrogen (H): 1
To balance hydrogen, place a coefficient of 2 in front of the hydrogen chloride (HCl) on the right side:
H2 + Cl2 → 2HCl
Step 3: Now, balance chlorine:
Left side (Reactants):
Chlorine (Cl): 2
Right side (Products):
Chlorine (Cl): 2
The chlorine is already balanced.
The final balanced equation is:
H2 + Cl2 → 2HCl
Now, the number of atoms of each element is the same on both sides of the equation, and it is balanced.
Summary:
Write the balanced equation for the following chemical reaction. Hydrogen + Chlorine → Hydrogen chloride
H2 + Cl2 → 2HCl
This equation shows that two molecules of hydrogen (H2) react with two molecules of chlorine (Cl2) to produce two molecules of hydrogen chloride (2HCl). The equation is balanced because the number of atoms of each element is the same on both sides of the equation.
