Introduction

Balancing chemical equations is a crucial step in chemistry that helps us understand the stoichiometry of chemical reactions. It involves adding coefficients to the reactants and products to ensure that the number of atoms of each element is the same on both sides of the equation. In this article, we will focus on balancing two chemical equations: $Li + CO_2 + H_2O \rightarrow LiHCO_3 + H_2$ and $CaH_2 + 2H_2O \longrightarrow Ca(OH)_2 + 2H_2$. We will use a step-by-step approach to balance these equations and provide a clear understanding of the process.

Balancing Equation 1: $Li + CO_2 + H_2O \rightarrow LiHCO_3 + H_2$

To balance this equation, we need to add coefficients to the reactants and products to ensure that the number of atoms of each element is the same on both sides of the equation.

Step 1: Count the number of atoms of each element on both sides of the equation

Element	Reactants	Products
Li	1	1
C	1	1
O	2	3
H	2	3

Step 2: Identify the elements that are not balanced

From the table above, we can see that the elements O and H are not balanced. There are 2 oxygen atoms on the reactants side, but 3 oxygen atoms on the products side. Similarly, there are 2 hydrogen atoms on the reactants side, but 3 hydrogen atoms on the products side.

Step 3: Add coefficients to balance the elements

To balance the oxygen atoms, we need to add a coefficient of 2 in front of $H_2O$ on the reactants side. This will give us 4 oxygen atoms on the reactants side, which is equal to the number of oxygen atoms on the products side.

To balance the hydrogen atoms, we need to add a coefficient of 2 in front of $H_2$ on the products side. This will give us 4 hydrogen atoms on the products side, which is equal to the number of hydrogen atoms on the reactants side.

Step 4: Write the balanced equation

The balanced equation is:

$Li + CO_2 + 2H_2O \rightarrow LiHCO_3 + 2H_2$

Balancing Equation 2: $CaH_2 + 2H_2O \longrightarrow Ca(OH)_2 + 2H_2$

To balance this equation, we need to add coefficients to the reactants and products to ensure that the number of atoms of each element is the same on both sides of the equation.

Step 1: Count the number of atoms of each element on both sides of the equation

Element	Reactants	Products
Ca	1	1
H	2	3
O	2	3

Step 2: Identify the elements that are not balanced

From the table above, we can see that the elements H and O are not balanced. There are 2 hydrogen atoms on the reactants side, but 3 hydrogen atoms on the products side. Similarly, there are 2 oxygen atoms on the reactants side, but 3 oxygen atoms on the products side.

Step 3: Add coefficients to balance the elements

To balance the hydrogen atoms, we need to add a coefficient of 2 in front of $CaH_2$ on the reactants side. This will give us 4 hydrogen atoms on the reactants side, which is equal to the number of hydrogen atoms on the products side.

To balance the oxygen atoms, we need to add a coefficient of 2 in front of $H_2O$ on the reactants side. This will give us 4 oxygen atoms on the reactants side, which is equal to the number of oxygen atoms on the products side.

Step 4: Write the balanced equation

The balanced equation is:

$CaH_2 + 2H_2O \longrightarrow Ca(OH)_2 + 2H_2$
