02 What is a Chemical Change & Activity 01 Classification of Chemical Changes

01) What is a chemical change?
A chemical change is a process that produces a new substance. The particles of the substance are broken apart and the atoms are rearranged into new particles, forming a new substance.

For example: Combustion of propane gas


02) Types of Chemical Changes/Reactions 

a) Combination 
b) Combustion
c) Decomposition 
d) Precipitation Reaction 
e) Acids & Bases Reaction 
f) Photosynthesis 
g) Respiration 

03) Activity 1 - Classifying Chemical Reactions 

Referring to activity 1 - Classifying Chemical Reactions (click here to access folder), go to 203_01_Classifying Chemical Reactions classify the equations according to categories as a group of three. After doing so, predict the classification used by other groups assigned for your group. The classification of the chemical reactions are listed on 02 Types of Chemical Changes/Reactions but at this point of time, you may also choose to classify in your own way based on the observation of the equations.
