To balance a chemical equation you need to ensure that the number of atoms of each element is equal on both sides of the equation. Here's the balanced chemical equation:

2H2+O2→2H2O

In this balanced equation, there are now two hydrogen atoms on each side and two oxygen atoms on each side, satisfying the law of conservation of mass.

## Balanced Chemical Equation

Chemical equations are used to describe chemical reactions that are represented by chemical symbols. A chemical equation will have a reactant, a product, and an arrow to indicate the direction of the reaction. When a specific chemical equation has an identical number of atoms on both the reaction side and the product side, it is known as a balanced chemical equation.

Solution:

To balance the equation: H2+O2→H2O

The equation represents the reaction between hydrogen gas (H2) and oxygen gas (O2) to form water (H2O).

To balance the equation, we need to ensure that the number of atoms of each element is the same on both sides of the equation.

On the left side, we have 2 hydrogen atoms from the H2 molecule.

On the right side, we have 2 hydrogen atoms from the H2O molecule.

Now let's balance oxygen (O) atoms:

On the left side, we have 2 oxygen atoms from the O2 molecule.

On the right side, we have 1 oxygen atom from the H2O molecule.

To balance the oxygen atoms, we need to multiply the water molecule by 2:

H2+O2→2H2O

Now the number of oxygen atoms is balanced.

The balanced equation is:

2H2+O2→2H2O

Summary:

## How would you Balance: H2+O2→H2O.

The chemical equation for the formation of water (H2O) can be written as:

2H2+O2→2H2O

This equation shows that two molecules of hydrogen gas (H2) react with one molecule of oxygen gas (O2) to produce two molecules of water (H2O). The equation is balanced with respect to the number of atoms on each side, with four hydrogen atoms and two oxygen atoms on both sides of the equation.
