In fact the words were never spoken out loud Those words were simply my own thoughts as I limped dejectedly out of a church building last month in Tipitapa Nicaragua about a fortyminute drive from downtown Managua Pastor Roberto Rojas a wellrespecte 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 Reactions. Investigation One.
