Skills Objectives for CHEM 1211 Exam 1 – Fall 2010
Listed below are some general skills that you should have mastered for success on the
first examination over textbook chapters 1 and 2.
Chapter 1.
1.
Be able to identify and differentiate between chemical and physical properties of
matter.
2.
Be able to identify and differentiate between chemical and physical changes of
matter.
3.
Be able to identify atoms, molecules, elements, compounds, and mixtures when
presented with a written or pictorial description.
4.
Know and be able to use common prefixes used in scientific notation (e. g. kilo,
centi, micro, etc.), and be able to represent units with these prefixes (k, c,
μ
, etc.)
with the correct power of ten when converted to the base unit (e. g. from
micrometer to meter).
5.
Be able to represent numbers in scientific notation or engineering notation. Be
able to represent numbers written in scientific notation correctly on your
calculator.
6.
Know the rules for significant figures, including when zeroes are significant. Be
able to determine the correct number of significant figures for numbers obtained
as the result of addition and/or subtraction, or multiplication and/or division. Be
able to do this for mixed formats, including decimal numbers, scientific notation,
or engineering notation. Know how the rules for significant figures change
between addition/subtraction and multiplication/division. Remember that the
number you calculate on your calculator may have more digits than are
significant. Be able to apply the rules for mixed calculations involving both
addition/subtraction and multiplication/division in any combination.
7.
Be able to do unit conversions from any unit to any other unit, given information
on conversion parameters. Be able to do this for cases in which multiple
conversions are needed (e. g. convert a distance in micrometers to a distance in
miles, or convert a rate of use – e. g. gallons/s  and time  e. g. days 
to total
consumption – e. g. liters).
