Dinosaur bones won't have any C14; that's all used up in about 50,000 years. The "freshest" dino bone you can find will be at least 65,000,000 years old. Actually, the dino bone will be so mineralized that there really won't be any "bone" left.
A fuel gas containing about 5o percent carbon monoxide 40 percent hydrogen and small amount of methane, carbon dioxide and nitrogen made by passing stem and air over heated coke and coal.

Cocaine is composed of carbon, hydrogen, and nitrogen. The approximate percent composition of cocaine is around 71.04% carbon, 8.64% hydrogen, and 20.32% nitrogen.
Lipids, such as fats and oils, do not typically have carbon-nitrogen bonds in their structure. Lipids are primarily made up of carbon, hydrogen, and oxygen atoms, with some containing phosphorus and sulfur, but not nitrogen.
Nitrogen is a key element in amino acids, the building blocks of proteins. Proteins are made up of chains of amino acids, with each amino acid containing nitrogen in addition to carbon, hydrogen, and oxygen. As a result, a certain percentage of nitrogen is present in proteins, with the average around 16 percent based on the composition of amino acids.
air is made of 19.98 percent oxygen 79 percent nitrogen and 2 percent carbon
Yes, carbon and nitrogen are both elements that are commonly found in the form of chemicals. Carbon is a vital element for life, forming the basis of organic molecules, while nitrogen is essential for protein synthesis and is often found in the form of nitrogen-containing compounds like ammonia and nitrate.
The atmosphere.
The four elements that make up 96 percent of living organisms are carbon, hydrogen, oxygen, and nitrogen. These elements are essential for building biological molecules such as proteins, DNA, and carbohydrates that form the fundamental structure of living organisms.
No, carbon dioxide is not a source of nitrogen compounds. Nitrogen compounds are typically derived from nitrogen-containing substances like ammonia or nitrates. Carbon dioxide is a greenhouse gas produced through processes like combustion.
No, carbon and oxygen are not the only elements that can combine with nitrogen. Nitrogen can also form compounds with hydrogen, sulfur, and other elements to create a variety of nitrogen-containing compounds.
