C) New atoms are created when a new substance is formed.

Explanation:

The mass conservation law was created by Antoine Lavoisier states that "in nature, nothing is lost, nothing is created and everything is transformed". This law stated that within a system where a chemical reaction occurs, the mass becomes a constant quantity, that is, the mass at the beginning of the reaction must be the same at the end of the reaction. This is because the number of atoms present in the reagents must be exactly the same as the number of atoms present in the product.

With that, we can affirm that the law of conservation of masses, affirm that in nature nothing is created, nothing is destroyed and the same number of atoms is in the products and in the reagents. However, this law denies that new atoms are created when a new substance is formed.

answer: carbon 14 can only be used to determine the age of the organisms that were once living, and igneous rocks are non living.

explanation:

carbon 14 dating is used to determine the age of the sample by estimating the amount of carbon 14 present in the sample and then comparing it with a reference standard.carbon 14 is a isotope of carbon which is radioactive and unstable. carbon 14 is assimilated by all plants and animals throughout their life from carbon dioxide. however, one the organisms die they stop this assimilation and the carbon 14 content starts to decrease.by knowing how much of carbon 14 is left in an organism after his death, one can estimate the age of the organism. the materials whose age can be estimated by carbon 14 method are the organic compounds. however, some inorganic compounds such as aragonite shell can also be dated.however, if we consider the igneous rocks it is a non living component which never accumulated carbon 14 in it and thus, we cannot use carbon 14 dating method to estimate its age.
