Radioactive carbon-14 is often useful in determining the absolute age of geologic samples because radioactive isotopes. 1 decay at a regular rate

2 become less stable during decay

3 remain unchanged over time

4 stabilize after four half-lives​

How is electrolysis most commonly used to produce an energy source? a - splitting water molecules produces oxygen, which organisms breathe to fuel their bodies. b - splitting water molecules produces hydrogen gas, which is used to power machines through hydrogen fuel cells. c - splitting carbon dioxide molecules produces coal, a form of carbon that can be burned to produce heat. d - splitting carbon dioxide molecules produces natural gas, which can be burned to generate electricity in power plants.
