The answer is; B
Rocks have naturally occurring and spontaneously radioactive atoms in them, such as carbon-14. These element isotopes decay into other types of atoms over millions of years. Therefore, by measuring the amount of these radiometric substances, and knowing the half-life of the isotopes, it is possible to postulate the age of a rock to within certain ranges of error.
Desity=V/M so you would divide 12.0 by 6 and you would get 2.
The answer is 2.
Liver contains a enzyme called catalase. When hydrogen peroxide (H2O2) is added to liver, a chemical reaction occurs which results in the production of oxygen gas (O2) and liquid water (H2O).
