PPT-Basic Chemical Reactions

What is a Chemical Reaction A Chemical reaction occurs when ever a chemical bond is formed broken or rearranged A chemical reaction will always create a new substance Energy and Chemical Reactions. 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. Chemical compounds are formed when two or more elements combine.. H. ₂ + O .  H₂O (water). Na + . Cl.  . NaCl. ( Sodium Chloride – Salt). Chemical Compounds. 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.

Chemical Reactions. :. A . chemical reaction . is a process that changes one set of chemicals into another by rearranging chemical bonds. The elements you start with are . reactants. The elements you end with are . 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 . Chemical Reactions. A . chemical reaction . is a process that changes, or transforms, one set of chemicals into another by changing the chemical bonds that join atoms in compounds. . @Mass and energy are conserved during chemical transformations.@. 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. Grade Science. Bowling Green Junior High. What are chemical reactions?. Chemical Reaction. . – . a change that takes place when two or more substances (reactants) interact to form new substances (products) with new properties.. What is a chemical reaction?. A . chemical reaction. is a process that converts one or more substances into another substance.. Chemical Reactions. The starting substances are the . reactants. .. The resulting substances are the . Synthesis Reaction. – combines two or more simpler reactants to form new, more complex products. .. N. N. O. O. O. O. N. 2. +. 2O. 2. 2NO. 2. +. Nitrogen. Oxygen.
