Atom -the submicroscopic particle that constitutes the fundamental
building block of ordinary matter.
-the smallest part of an element that still has characteristics of
that element.
Matter -matter is composed of tiny particles, may be atoms or
molecules.
-anything that occupies space and has mass.
A sample of liquid isopropyl alcohol is No, the mass stays the same during the vaporization. This is
placed in a sealed container. Some of the because the isopropyl alcohol is just in a different physical
volatile isopropyl alcohol vaporizes. Does state now. Because The Law of Conservation of Mass states
the mass of the sealed container and its matter cannot be created or destroyed, the mass in the
contents change during the vaporization? container will stay constant.
Explain.
What is the difference between a physical Physical Property: something that can be observed without
property and a chemical property? changing the chemical identity of the substance, such as color
or scent.
Chemical Property: can only be observed while the chemical
identity of the substance is changing, such as sodium metal's
tendency to react with water to form hydrogen gas and
sodium hydroxide.
Energy The ability to do work or produce heat.
Kinetic: energy of motion
Potential: energy of position
The Law of Conservation of Energy Energy cannot be created or destroyed.

many bytes does it contain?
Describe the difference between an -An Intensive Property does NOT depend on the amount of
intensive and extensive property using the substance present, such as color or density. (can be used
examples. to identify a substance because it does not change with the
amount of matter present)
-An Extensive Property is one that does depend on the
amount of the substance, such as mass or volume. (cannot be
used to help identity a substance because it changes)
A mass of mercury occupies 0.950 L. What B) 16.3 L
volume would an equal mass of ethanol
occupy? the density of mercury is 13.546 (.950 L) x (1000mL / 1L) x (13.546g / 1mL) x (1mL / .789g) = 16,310
g/mL and the density of ethanol is 0.789 mL = 16.3 L
g/mL.
Which of the following is the lowest C) 57 degrees F
temperature? ----------------------------
A) 42 degrees c A) 42 c

Sig Fig Rules -Non-zero digits are always significant.
-Any zeros between two significant digits are significant.
-A final zero or trailing zeros in the decimal portion ONLY are
significant.
Addition and Subtraction:
answer must show the same number of decimal places as the
number in the calculation with the least number of decimal
places.
Multiplication and Division:
answer must show the same number of significant digits as the
measurement in the calculation with the least number of
significant digits.
An atom of 131^ Xe contains ___ electrons. D) 54 electrons (mass number)
The atomic number of an atom of 80^Br is A) 35
An ion has 8 protons, 9 neutrons, and 10 A) 17O^2-
electrons, The symbol for the ion is _____
Isotopes -Isotopes are atoms with the same number of protons but that
have a different number of neutrons.
-Since the atomic number is equal to the number of protons
and the atomic mass is the sum of protons and neutrons, we
can also say that isotopes are elements with the same atomic
number but different mass numbers.
-number of neutrons=
atomic mass-atomic number

What is the identity of element Q if the ion A) Mg
Q2+ contains 10 electrons?
If Q2+ ion has 10 electrons then element Q should have 10+ 2
electrons.
(no of electrons in the ion + no of electrons lost)
Describe the difference between ions and Ions have the loss or gain of electrons (have a net electric
isotopes. charge), Isotopes differ in the number of neutrons
Why doesn't a mass spectrum of silver have The average atomic mass of silver is 107.9 amu, but there are
a peak at 107.9 amu? no atoms of silver that weigh 107.9 amu. One isotope weighs
more and another weighs less.
