1.1 Chemicals All Around Us

Chemical Storage and Disposal

Most chemicals pose a danger if not handled, stored or

disposed of correctly. They might be:

o _______________ (WD40),

o ______________ (butane - curling irons, lighters),

o ______________ (lye – drain and oven cleaners),

o _______________(glycol – antifreeze) or

o _______________ (ammonia and chlorine).

Some chemicals are useful because they are

dangerous

o Examples: 1)___________________

2)___________________

Other chemicals become dangerous at high

concentration or over long exposure

o Example: _________________________



Special care is also needed when disposing of chemical

substances.

o Example: ___________________________

Many products have _______________________on

them.

o Labels give you instructions as to how to _______

________________________________________

o ______________________________________ca

n be taken to a municipal collection site.

1.2 Describing Matter

_________________ is anything that has mass and

takes up space.

Democritus, a Greek philosopher thought all matter was

made up of tiny bits too small to be seen.

o He called these tiny bits _______________, after

the Greek word for uncuttable.

The _________________________ describes the

behavior and nature of atoms in different substances.

o A _____________________ is an explanation of

something that has been supported by repeated

experiments.



The Particle Theory of Matter

__________________.

All particles of a __________ substance are the

same.

There are _____________ between the particles.

Particles are always ________________.

The particles in a substance are ________________

to each other.

States of Matter

Matter exists in three basic states:

o _________________

o __________________

1.3 Classifying Matter

Using the particle theory we can classify substances into

two basic categories based on _____________________

_______________________________________.

____________________ substances are made up of only

one type of particle.

o All parts of the substance are identical.

o Examples: _________________________________

____________________________

Matter

Mixture Pure

Substance



____________________ contain more than one type of

particle.

o In some mixtures the substances that make up the

mixture are evident

For example __________________________

o For other substances the components can not be

distinguished with the naked eye

For example __________________________



How do you tell if a substance is pure or a mixture?

1. Examine the substance’s ______________________

______________.

You might be able to tell them apart by _______,

________, __________ or ___________.

2. Examine the substance’s ______________________.

Mixtures _______________________________

________________ than the pure substances that

make them up.

o Pure water freezes at 0ºC at sea level.

o Adding salt to ice on a highway, lowers the

freezing point of the salt-water mixture to the

point that it will not freeze on a typical winter

day.
