Chemical Reactions ( Dr. Bülent BELİBAĞLI )

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

Chemical Reaction

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.
