Test

Let's get studying! This website has helpful practice problems. Try the

"Energy" and "Radioactive Decay" tests.

Know how to...

• use half-life to find percentage of parent isotope left

• identify a graph of a parent's decay and daughter isotope

• identify the different decay rates of isotopes

• determine which isotope is best to use based on the age of the sample sample

• identify the correct phase changes for the different states of matter

• determine percentage of isotopes in a graphic format

• use RT page 1, Specific Heat, Properties of Water, and Half Life and RT10 composition of the earth's interior layers

• calculate age of a sample using half life

• change the rate of a chemical reaction, by changing different variables (like temperature or surface area)

• use a decay graph to determine the half life of an isotope

• relate percentage with the number of half-lives an isotope has been through
