Why can some things burn while other things
cannot burn?Why does ethanol behave more like
wood than like water?
Driving questions

What ATOMS are found in these materials?
9
What ATOMS are found in these materials?
ATOMS FOUND IN EACH MOLECULE Water Hydrogen,
Oxygen Ethanol Hydrogen, Oxygen, Carbon Wood
Hydrogen, Oxygen, Carbon
10
What BONDS are found in these materials?
11
What BONDS are found in these materials?
BONDS FOUND IN EACH MOLECULE Water
H-O Ethanol H-O, C-O, C-H, C-C Wood H-O, C-O,
C-H, C-C
12
What BONDS are found in these materials?
Chemical Energy Energy found in the bonds of
molecules. C-C and C-H bonds means molecules
have available chemical energy. So which
materials have available chemical energy?
13
MATTER AND ENERGY

• Every molecule has both ATOMS and BONDS

ATOMS TELL YOU ABOUT MATTER
BONDS TELL YOU ABOUT ENERGY
14
Materials That Burn
Materials That Do NOT Burn
WATER
SALT
CARBON DIOXIDE
OXYGEN
NITROGEN
15
How are these different?
What makesthese burn?
WATER
SALT
CARBON DIOXIDE
OXYGEN
NITROGEN
16
Water, Ethanol, and Wood

• Ethanol and wood both have C-C and C-H bonds.

Ethanol molecule (C2H5OH)
Water molecule (H2O)
Cellulose (C6H10O5)n

ORGANIC
INORGANIC
--means the molecule has C-C and C-H bonds
--means the molecule does not have C-C and C-H
bonds
