  1. Chemical Reactions Reactants = starting materials Product(s) = what is produced during the reaction 2H2 + O2 2 H2O reactants products Balanced equation = number of atoms of each element must be the same on each side.

  2. Chemical Bonds • Single bond -represented by one line, each line represents two electrons; one from each atom of the element being bonded for a total of 2 shared O2 O-O • Double bond - represented by two lines, each line represents two electrons for a total of 4 shared O2 O=O • Triple Bond - represented with three lines, each line represents two electrons for a total of 6 shared O2 O=O

  3. Single,Double, and Triple bonds *Student will work in pairs. Each pair will have 3-Carbons, 8-Hydrogens, 1-triple bond, 2-double bonds, and 8-single bonds. Using the materials provided, make the following bonds compounds. DRAW THE FINAL REULST IN YOUR COMPOSTION BOOK **REMINDER - a bond represents two electrons, one from each atom of an element** CH4 ; C2H6; C2H4 ; C2H2 ; C3 H4 (using 2-double bonds), C3H4 with a triple bond.
