Lets get started How do you know when a chemical reaction takes place Color Change Precipitate Formation How do you know when a chemical reaction takes place Gas Formation Odor How do you know when a chemical reaction takes place. 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. PHYSICAL PROPERTY . - A feature or characteristic of matter which can be observed without changing the identity of the matter . Examples. :. . . Color. 1 – Nature of Chemical Reactions. 2 – Chemical Equations. 3 - Reaction Types. 4 – Reaction Rates and Equilibrium. State Standards. CLE.3203.1.9 – Apply the Laws of Conservation of Mass/Energy to balance chemical equations. Chemical Equations. This equation means:. 4 Al(. s. ) + 3 O. 2. (. g. ) 2 Al. 2. O. 3. (. s. ). 4 Al atoms + 3 O. 2. molecules yield 2 molecules of Al. 2. O. 3. 4 Al . moles. Holt Science & Technology:. Physical Science. Chapter 14 Chemical Reactions.
