Is it Physical or Chemical?
State if each scenario is a Physical property/change or a Chemical
property/change. (refer to the chart for “WHY?”).
EXAMPLE (scenario)
PHYSICAL OR CHEMICAL?
WHY?
Melting a snowman
An Iron fence changing into a
green color when exposed to
oxygen.
Watching wood burning at a
campfire and turning to ask.

Law of Conservation of Mass (pg. 109)
Calcium + Chlorine
= Calcium Chloride
10 grams + 30 grams = ???
Based on the Law of Conservation of Mass, what must the mass of Calcium Chloride be?
The mass of a block of wood is 25 grams. It is placed in a fire and turns to ash. The mass of the ash is 15
grams. Did you just destroy the other 10 grams and prove the Law of Conservation of Mass to be false? Or
can you explain what actually happened?
