2. ïĄ The student will:
ï§ Distinguish the difference between a
chemical and a physical change
ï§ Investigate and understand physical
changes in matter
ï§ Investigate and understand chemical
changes in matter
ï§ Investigate and understand chemical
formulas and the types of bonds found in
simple compounds
3. ïĄ The Law of Conservation of
Mass/Matter
ïĄ Chemical Change
ïĄ Physical Change
ïĄ Chemical Formula
ïĄ Chemical Equation
ïĄ Reactant
ïĄ Product
4. ïĄ States that
mass/matter is
neither lost or
gained during a
reaction, though
it may change in
substance, form,
phase or state
5. ïĄ When a substance
changes its size or
shape or phase/state of
matter but still retains
the properties of the
original substance
ï§ i.e.:
âȘ Paper being torn
into little pieces
6. ï§ When a new
substance is created
through the
combination of
chemicals or energy
ï§ i.e.:
âȘ Paper burning and
turning into ash
(carbon)
7. ïĄ The way a
substance or
compound is
expressed
symbolically
âȘCO2 is Carbon
Dioxide
âȘH2O isWater
âȘC6H12O6 is
Glucose
8. ïĄ A math-like equation that shows
how chemicals are combined
ï§C + O2 ï CO2
âȘï means âYieldsâ
9. ïĄ The chemicals combined in a
chemical equation
ïĄ Located on the left side of the
equation
ï§Carbon (C) + 2 Oxygen atoms
(O2)
âȘ2O+C ï CO2
10. ïĄ The final
outcome of a
chemical reaction
ïĄ Located on the
right side of the
equation, (right of
the yields symbol
ï )
ï§C + O2 ï CO2
âȘCarbon (C )+ 2
Oxygen atoms (O2)
= Carbon Dioxide
(CO2)
