Introduction

Balancing chemical equations is a crucial step in understanding chemical reactions. It involves adjusting the coefficients of the reactants and products to ensure that the number of atoms for each element is the same on both sides of the equation. In this article, we will balance the chemical equation $2 \, H_2 + O_2 \rightarrow 2 \, H_2O$ and calculate the number of atoms for each element.

Step 1: Write the Unbalanced Equation

The given chemical equation is $2 \, H_2 + O_2 \rightarrow 2 \, H_2O$. This is the unbalanced equation, which means that the number of atoms for each element is not the same on both sides of the equation.

Step 2: Count the Number of Atoms for Each Element in the Reactants

To balance the equation, we need to count the number of atoms for each element in the reactants.

• Hydrogen (H): There are 2 molecules of $H_2$, each containing 2 hydrogen atoms. Therefore, the total number of hydrogen atoms in the reactants is $2 \times 2 = 4$.
• Oxygen (O): There is 1 molecule of $O_2$, which contains 2 oxygen atoms. Therefore, the total number of oxygen atoms in the reactants is 2.

Step 3: Count the Number of Atoms for Each Element in the Products

Next, we need to count the number of atoms for each element in the products.

• Hydrogen (H): There are 2 molecules of $H_2O$, each containing 2 hydrogen atoms. Therefore, the total number of hydrogen atoms in the products is $2 \times 2 = 4$.
• Oxygen (O): There are 2 molecules of $H_2O$, each containing 1 oxygen atom. Therefore, the total number of oxygen atoms in the products is $2 \times 1 = 2$.

Step 4: Balance the Equation

Now that we have counted the number of atoms for each element in the reactants and products, we can balance the equation. To balance the equation, we need to adjust the coefficients of the reactants and products so that the number of atoms for each element is the same on both sides of the equation.

The balanced equation is $2 \, H_2 + O_2 \rightarrow 2 \, H_2O$. However, we can see that the number of oxygen atoms in the reactants is 2, but the number of oxygen atoms in the products is also 2. Therefore, the equation is already balanced.

Conclusion

In conclusion, we have balanced the chemical equation $2 \, H_2 + O_2 \rightarrow 2 \, H_2O$ and calculated the number of atoms for each element. The balanced equation is $2 \, H_2 + O_2 \rightarrow 2 \, H_2O$. We have also counted the number of atoms for each element in the reactants and products, which is 4 for hydrogen and 2 for oxygen.

Discussion

Balancing chemical equations is an essential step in understanding chemical reactions. It involves adjusting the coefficients of the reactants and products to ensure that the number of atoms for each element is the same on both sides of the equation. In this article, we have balanced the chemical equation $2 \, H_2 + O_2 \rightarrow 2 \, H_2O$ and calculated the number of atoms for each element.

Calculating the Number of Atoms for Each Element

To calculate the number of atoms for each element, we need to count the number of atoms in each molecule and multiply it by the number of molecules.

• Hydrogen (H): There are 2 molecules of $H_2$, each containing 2 hydrogen atoms. Therefore, the total number of hydrogen atoms is $2 \times 2 = 4$.
• Oxygen (O): There is 1 molecule of $O_2$, which contains 2 oxygen atoms. Therefore, the total number of oxygen atoms is 2.

Answer

The number of atoms for each element is:

• Hydrogen (H): 4
• Oxygen (O): 2

Final Answer

The final answer is:

• Hydrogen (H): 4
• Oxygen (O): 2
