PPT-Chemical Reactions This is the fourth text which will be used for practicing dictation

The key words are emphasized in bold and there is a list of them at the end of the presentation Chemical Reactions When a chemical reaction occurs new substances called products form from the substances taking part in the reaction called . 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. Dictation. With . Automatic. . Speech. .
