Why doesn't hydrogen produce carbon dioxide?

How could it? There is no carbon in hydrogen. It order to make carbon dioxide, you must have carbon and oxygen.


What gas is denser carbon dioxide or hydrogen?

Carbon dioxide is denser.


Do oxygen and hydrogen and carbon dioxide weigh the same?

No, oxygen, hydrogen, and carbon dioxide do not weigh the same. They have different atomic masses, with oxygen being heavier than hydrogen and carbon dioxide being heavier than both oxygen and hydrogen.


What expands the most when heated hydrogen peroxide carbon dioxide or iron?

A gas as carbon dioxide is easily expanded by heating; hydrogen peroxide is decomposed.


If you burn hydrogen do you get carbon dioxide?

No, burning hydrogen does not produce carbon dioxide. When hydrogen is burned, it reacts with oxygen to form water vapor, releasing energy in the process. Carbon dioxide is produced when carbon-containing fuels, such as fossil fuels, are burned.


Does the hydrogen on methane go when it becomes carbon dioxide?

Methane burns in oxygen and gets oxidised. Carbon is oxidised to carbon dioxide, hydrogen to water.

Name three gasses?

Carbon dioxide, carbon monoxide, hydrogen.


Is carbon dioxide a hydrogen bond?

No, carbon dioxide does not have hydrogen bonds. It is a linear molecule composed of one carbon atom and two oxygen atoms, so it does not have hydrogen atoms to form hydrogen bonds. Instead, carbon dioxide molecules are held together by weak London dispersion forces.


Are hydrogen on carbon compounds?

No, not all compounds of Carbon contain Hydrogen, for instance Carbon Dioxide does not and neither does Carbon Tetraflouride.


Why are carbon dioxide and carbon monoxide are not example of organic chemistry?

Carbon dioxide and carbon monoxide are not examples of organic chemistry because they do not contain hydrogen atoms bonded to carbon atoms. Organic chemistry focuses on compounds that contain carbon-hydrogen bonds, whereas carbon dioxide (CO2) and carbon monoxide (CO) consist of carbon atoms bonded to oxygen atoms instead.


A difference between hydrogen and carbon dioxide?

One key difference between hydrogen and carbon dioxide is their chemical composition. Hydrogen is a diatomic molecule composed of two hydrogen atoms (H2), while carbon dioxide is a compound composed of one carbon atom and two oxygen atoms (CO2). Additionally, hydrogen is a flammable gas with no color or smell, while carbon dioxide is a colorless and odorless gas that is not flammable.
