Which statement accurately describes radioactive dating? a geologists use only one type of radioactive dating. b geologists compare parent and daughter elements to determine rock type. c geologists measure how stable parent elements decay into daughter elements. d geologists determine half-life as radioactive elements get trapped in rock and break down over time.

Radioactive dating is the technique in which radioactive isotopes are used to estimate the age of rocks and minerals. There are many different radioisotopes used for radioactive dating like Carbon, Uranium, and Potassium. Radioactive dating works on the principle that a radioactive isotope can decay into the stable daughter nuclei at a constant rate. Geologist generally use the principle for half life. Half life is the time required for half of the radioactive substance to decay. This is constant for a particular element.

Therefore, the correct option is,

D. as the geologists use the half life of the radioactive elements present in the rocks to estimate the age of rock.

answer is: c. the experiment shows that the red substance experienced a chemical change.

this is chemical change (chemical reaction), because two new substances are formed (metalig liquid and gas), the atoms are rearranged and the reaction is followed by an energy change.

this is example of chemical decomposition.

chemical decomposition (analysis) is the separation of a single chemical compound into its two or more elemental parts or to simpler compounds.  

chemical decomposition is opposite of chemical synthesis.

dynamic equilibrium is the answer.
