CHEMISTRY 130 ARIZONA COLLEGE OF
NURSING MIDTERM EXAMS SET SOLVED
QUESTIONS AND CORRECT ANSWERS
GRADED A+
⩥ Three states of matter?
Answer: solid, liquid, gas
⩥ Scientific Notation
Answer: Scientific system of writing numbers. A method to write very
big or very small number easily
⩥ Scientific Notation composed of three parts
Answer: mathematical sign, the significand, and the exponential
⩥ Significand
Answer: base value of the number or the value of the number when all
the values of ten are removed. example -9.0462 x 10^3. the significand
is -9.0462
⩥ Exponential
,Answer: is a multiplier of the significand in powers of ten. example -
9.0462 x 10^3. the exponential is 10^3
⩥ HESI Hint: Exponent
Answer: some calculators or other devices may write the exponent as an
"e" or "E" as in 3.2 e5 or 3.2E5 instead of 3.2 x 105, which is called E
