PPT-Chemical vs. Electrochemical Reactions

Chemical reactions are those in which elements are added or removed from a chemical species Electrochemical reactions are chemical reactions in which not only may elements may be added or removed from a chemical species but at least one of the species undergoes a change in the number of valance . 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. ELECTRICITY. . & CHEMISTRY. N5. CHEMISTRY. N5.
