In chemistry, a compound is a substance made up of two or more different chemicalelementscombined in a fixed ratio. When the elements come together, they react with each other and form chemical bonds that are difficult to break. These bonds form as a result of sharing or exchangingelectronsbe...
Organic chemistry is all about studying carbon-based molecules. These are found in living things, like plants and animals, but also in things we use every day, like plastics, fuels, and medicines. Organic chemists learn how these molecules form, react, and create new substances. ...
If an organism had 100 grams of carbon-14 when it died, after 5730 years, how many grams of carbon-14 would it have? In which year did Willard Libby win the Nobel Prize in Chemistry? Who were the other two scientists responsible for developing carbon dating?
