Comets contain a small amount of so-called "heavy water" composed of equal parts hydrogen, oxygen, and deuterium. (Deuterium is an isotope of hydrogen with one extra neutron in its nucleus.) The chemical formula of heavy water is HDO; normal water is H2O.
Comets contain ice.
Comets contain various types of ice (water and also other frozen liquids or gases) which sublime to vapor when the comet approaches the inner solar system.
No.
Comets
Comets are made up of dust, rock, ice, and frozen gases. The most common compounds found in comets include water ice (H2O), carbon dioxide (CO2), ammonia (NH3), methane (CH4), and carbon monoxide (CO). Additionally, comets can contain organic molecules such as formaldehyde and methanol.
Ice
no according to justin bieber there is no water in comets
They are often referred to as 'dirty ice balls.' So I would say that they are mostly made of water and contain only a little bit of dirt.
solid iron.
Yes, comets are often considered storehouses of chemicals. They contain a variety of compounds such as water ice, carbon dioxide, ammonia, and methane. Studying these chemicals can provide insights into the early solar system and the origins of life on Earth.
Comets contain ice.
Because there aren't always comets!
