how to balance chemical equations step by step pdf

Definition of Balancing Chemical Equations

Steps to Balance Chemical Equations

Step 1: Write the Unbalanced Equation

Step 2: Identify the Elements to Balance

Look for elements that appear only once on each side of the equation, as these will be the easiest to balance.

Next, identify elements that are present in multiple compounds on the same side of the equationas these will require careful consideration to balance.

Use a systematic approach to identify the elements to balanceworking from left to right and top to bottom.
