Explanation
## Step 1: Balancing chemical reactions involves ensuring that there is the same amount of each element on both sides of the chemical equation. ## Step 2: To balance the equations, we need to adjust the coefficients (the numbers in front of the reactants and products) until the number of atoms for each element is the same on both sides of the equation.## Step 3: We balance each equation one by one.
