There are two sets of symbols: WHMIS and Safety Hazard
Symbols. Which one is most likely to be used in the home?
ANSWER
Safety Hazard Symbols- They are the symbols that indicate
degree as well as what type of hazard they possess.
Extra Info:
WHMIS- they only indicate the type of hazard. H2O2 is very
reactive and can burn your skin. Battery acid is corrosive.

OH NO! I broke a beaker containing toxic ammonia. What
do I do?
Answer
Warn everyone around you that there is glass broken and a
toxic substance is spilled. Then, tell the lab teacher
immediately, the spill should be cleaned up by someone
qualified to do it (the teacher).

When organizing matter, we organize according to chemical
and physical properties as well as changes. I often get
confused between physical and chemical properties. What is
the difference?
Answer
Physical properties describe physical appearance and
composition while chemical properties describe interactions
between chemicals.
Physical Properties
Chemical Properties
Melting point/boiling point Reaction with acids
Hardness
Ability to burn
Malleability/ductility
Reaction with water
Crystal shape
Behaviour in air
Solubility
Reaction to heat
Density
Conductivity



Occurs between two non-metals
Exist as a solid, liquid, or gas at room temperature
Are insulators
Low melting and boiling points
When two non-metals come into contact with one
another their electrons are shared.
The bond formed is called a covalent bond.

Combustion is a type of reaction that involves oxygen. Is
this an example of an endo- or exo-thermic reaction? What is
the definition of each of these?
Answer
It is an exothermic reaction, meaning it gives off heat or
energy. Endothermic reaction needs heat or energy in order
for a reaction to take place.
Jeopardy Board
What is the law of conservation of mass?
Answer
It states that mass can neither be created nor destroyed. In
other words, whatever mass your reaction starts with, you
will have the exact same mass as products.
Jeopardy Board
What is an open system in terms of chemical reaction? What
is the opposite system?
Answer
An open system is one in which the products can leave the
system, this is not to say that law of conservation of mass
does not apply, it simply states that some of the products
may be a gas form and may leave the system without a way
to measure the total products produced. A closed system the
reaction takes place inside an enclosed space where nothing
can leave nor enter the reaction.
Jeopardy Board
There are four factors that affect the rate of reactions, please
state all of the ones the you have learned.
Answer
1)
2)
3)
4)
Catalysts- they speed up the reaction, but do not take
part in the reaction. They will still be there when the
reaction is finished.
Concentration- the higher concentration you have the
faster the reaction will be as there are more particles
available to collide with one another; thereby, increasing
the reaction process.
Temperature- the higher temperature allows particles to
move faster; therefore, they are more likely to collide
with one another….increasing the rate of reaction.
Surface area- the larger surface available to react the
more collisions you are going to have therefore faster
reaction.
