Chemical Reactions and the Chemical Equation
A chemical reaction is a process in which one set of substances called reactants is converted to a new set of substances called products.
As reactants are converted to products we observe:
– Color change
– Precipitate formation
– Gas evolution
– Heat absorption or evolution
Step 1: Write the reaction using chemical symbols.
Step 2: Balance the chemical equation.
In a balanced equation the total number of atoms of each element is the same on both sides.
