HELP ME/Science Atoms of carbon-14 are radioactive. They decay into
atoms of the element nitrogen. Suppose that a sample of
rock is taken from a fossil. The sample has 1000 atoms of
carbon-14 and 1000 atoms of nitrogen.
If carbon-14 has a half-life of 5700 years, how old is the fossil?
O A. 2850 years old
O B. 17,100 years old
O c. 5700 years old
O D. 11,400 years old

when atoms of different types of elements join together, they make molecules called compounds. water consists of compound molecules made up of 2 hydrogen atoms and 1 oxygen atom. this is why it's called h2o. water will always have 2 times the number of hydrogen atoms as oxygen atoms.

igneous rocks are formed by solidification of cooled magma (molten rock), with or without crystallization, either below the surface as intrusive (plutonic) rocks or on the surface as extrusive (volcanic) rocks.  

the composition depends on the source magma. there are almost a thousand types of composition found till now.  

hope this

what are the options
