1. Explain: what is the purpose of balancing a chemical equation? 2. Explain briefly how you balance an equation.

The purpose of balancing a chemical equation is to get the correct proportions of reagents and products for a reaction.

How to balance the Chemical Equation:
Step 1: count the number of atoms on each side of the equation
Step 2: Look at coefficients (the number In front of the element) and balance the equation
Step 3: ONLY CHANGE COEFFICIENTS
Step 4: Count polyatomic ions as one item

Answer for 1: The purpose of balancing a chemical equation is to obtain the correct products for a given reaction

Answer for 2:
Step 1: Write the unbalanced chemical equation

Step 2: Write down the number of atoms

Step 3: Add coefficients to balance mass in a chemical equation

Step 4: balance oxygen and hydrogen atoms
