The balanced chemical equation you provided shows the reaction between hydrogen peroxide (H2O2) gas and carbon monoxide (CO) gas to produce hydrogen gas (H2) and carbon dioxide gas (CO2).

To understand this reaction, let's break it down step by step:

1. Start with the reactants: H2O2(g) + 2CO(g)
This means that you have one molecule of hydrogen peroxide gas and two molecules of carbon monoxide gas.

2. Observe the arrow (�¨) which indicates a chemical reaction is taking place.

3. Look at the products: H2(g) + 2CO2(g)
This means that the reaction results in one molecule of hydrogen gas and two molecules of carbon dioxide gas.

Now, to balance the equation, we need to adjust the coefficients of the reactants and products. Currently, the equation is not balanced because the number of atoms on each side of the equation is different.

Here's how to balance the equation:
1. Count the number of atoms for each element on both sides of the equation.
On the left side (reactants):
- Hydrogen: 2 atoms (2 from H2O2)
- Oxygen: 3 atoms (2 from H2O2 and 1 from CO)

On the right side (products):
- Hydrogen: 2 atoms (2 from H2)
- Oxygen: 4 atoms (2 from H2O2 and 2 from CO2)

2. Since the number of oxygen atoms is not balanced, we need to add a coefficient to the appropriate molecule(s) to balance the equation.

By placing a 2 coefficient in front of H2O2 on the left side, the number of oxygen atoms becomes balanced.

The balanced chemical equation is:
2H2O2(g) + 4CO(g) �¨ 2H2(g) + 4CO2(g)

Now, the equation is balanced. It indicates that when two molecules of hydrogen peroxide gas react with four molecules of carbon monoxide gas, it produces two molecules of hydrogen gas and four molecules of carbon dioxide gas.
