, Chemistry is the study of? Answer: Matter and it's properties
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 notation
Metric System Answer: method to measure weight, length, and volume
Basic measurements for metric system Answer: grams, liters, and meters
Basic measure of weight Answer: gram
Basic measure of liter Answer: volume
Meter Answer: Basic measure of distance
