TO THE MODULE #1 STUDY GUIDE
1.
a. An atom is the smallest chemical unit of
matter.
b. A molecule is two or more atoms linked together to make a
substance with unique properties.
c. Concentration is the quantity of a
substance within a certain volume
2. Carbon disulfide is made up of molecules.
3. Rust is not attracted to a magnet because when
an atom is a part of a molecule, the molecule does not take on the
characteristics of the atom. Instead,
the atoms in the molecule join together in such a way as to give the molecule
its own unique characteristics.
4. The statue will eventually turn a shade of
green, just like the copper wire did in Experiment 1.1. This comes from the copper atoms reacting
with water and carbon dioxide in the air to make copper hydroxycarbonate.
5. Scientists have NOT seen atoms. The scanning tunneling electron microscope
“pictures” that you see are not pictures of atoms. Instead, they are the result of computer
calculations involving electricity and a theory call quantum mechanics.
6. The prefix centi
means 0.01; the prefix milli means 0.001; and the
prefix kilo means 1,000.
7. Mass is measured in grams in the metric
system. In the English system, it is
measured in slugs.
8. Volume is measured in liters in the metric
system. In the English system, it is
measured in gallons, pints, or quarts.
9. Length is measured in meters in the metric
system. In the English system, it is
measured in feet, yards, inches, or miles.
10. 
1.3 m is the same as 130 cm.
11. 
The person’s mass is 75,000 g.
12.
There are 1.89 L in 0.500 gallons.
13. 
There
are 39.4 inches in a meterstick.
14. Baking bread is not a
dangerous activity because the ozone it produces is not concentrated enough to
be dangerous. Ozone is a poison, but at
low enough concentrations, it does not adversely affect people. At higher concentrations, however, it can be
toxic enough to kill you!
