PPT-CHEMICAL REACTIONS ENERGY IN CHEMICAL REACTIONS

All chemical reactions either release or absorb energy The energy can take many forms HEAT LIGHT SOUND and ELECTRICITY Chemical bonds are the source of this energy . DEFINITIONS AND TYPES. Revision:. DO NOT WRITE- FOR YOUR INFO ONLY. We have looked at the period table, what atoms are, elements and compounds. You have learnt that atoms can join to make compounds or molecules and that we can mix compounds to make new compounds…..these are chemical reactions. Energy, Rates, and Equilibrium.
