PPT-Chemical Reactions Aim to look at a ‘varity of reactions…’

Synthesis reactions Decomposition reactions Single replacement reactions Double replacement reactions Precipitate reaction Chemical Reactions can be written as Word equation Chemical equation. 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. Physical Science Notes. Physical Properties.

Add the new notes to your . table of contents. , and then turn to the next clean page and set up your title and date. Tape the two slides into your INB flat down, directly under your title - they do not need to flip up. 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 . THINK ABOUT IT . Living things are made up of chemical compounds, but chemistry isn’t just what life is made . of—chemistry is also what life does. . . Everything that happens in an organism. —its growth, its interaction with the environment, its reproduction, and even its movement. CONTENTS. CHEMICAL REACTION. CHARACTERISTICS OF CHEMICAL REACTION.
