PPT-Describing Chemical Reactions

Chemical Reactions A chemical reaction is the process by which one or more substances change into one or more new substances Reactants are the original substances in a chemical reaction Products . 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. Chemical change. . Reactions with acid. .

Describing Others AND MYSELF We have worked in the last two weeks on describing others. This lesson focuses in on the changes in pronouns and verb conjugations that take place in order to shift from describing someone else to describing oneself.
