Apex
Answer:
Nitrogen
Explanation:
It is the most abundant gas in the atmosphere.
Partial pressure is the pressure that would be exerted by one of the gases in a mixture if it occupied the same volume on its own. For a mixture of gases, each gas has a partial pressure which is the hypothetical pressure of that gas if it alone occupied the volume of the mixture at the same temperature.
Answer:
Radiocarbon measurement or radiocarbon dating is a method that is used to measure the age of the carbon-based material in living organisms.
Radiocarbon dating is able to estimate age of fossils that are younger than 50,000 years and unable to measure things that died longer than 200,000 years ago because fossils that are too old do not contain carbon or carbon get vanished from too old fossils of organisms. Some of the fossils also get contaminated due to environmental conditions and during teh collection or preservation process.
Thus, radiocarbon measurement is useless when trying to measure most rocks older than 50,000 years.
