Carbon dioxide, methane are the two more common compounds.
During the Jurassic period, the atmosphere was primarily composed of nitrogen, carbon dioxide, and oxygen, similar to the composition of the modern-day atmosphere.
Gases
The Earth's atmosphere is mainly composed of nitrogen (about 78) and oxygen (about 21), with trace amounts of other gases like argon, carbon dioxide, and water vapor.
Gases
The atmosphere of Uranus contain hydrogen, helium, methane, etc.
Sugar is a carbohydrate made up of carbon, hydrogen, and oxygen molecules. The most common type of sugar, sucrose, is composed of one molecule of glucose and one molecule of fructose bonded together. The chemical formula for sucrose is C12H22O11.
They both have a chemical makeup of carbon.
Carbon and hydrogen atoms
Zinc is only a metallic chemical element.
The ozone in atmosphere is formed by UV. The UV replenishes it and then depletes it.
2 -- Cl2 is a molecule of Chlorine and as can be seen it has two atoms.
The Earth's atmosphere is made up of gases like nitrogen, oxygen, and carbon dioxide. These gases trap heat from the sun, creating a greenhouse effect that warms the planet. However, human activities, such as burning fossil fuels, release more greenhouse gases into the atmosphere, leading to global warming and climate change.
