No, oxygen and nitrogen are gases that do not contain water. Water is made up of two hydrogen atoms and one oxygen atom. Oxygen and nitrogen are elements that exist as gases in the Earth's atmosphere.
Oxygen. The early Earth's atmosphere was composed primarily of gases such as carbon dioxide, water vapor, nitrogen, and methane. Oxygen levels increased with the development of photosynthetic organisms.
Oxygen. Earth's early(first) atmosphere is believed to contain hydrogen cyanide, carbon dioxide, carbon monoxide, nitrogen, hydrogen sulfide, and water. but still it only had little to no oxygen.
Water (H2O) contains hydrogen and oxygen, but does not contain nitrogen or carbon. Water is composed of two hydrogen atoms bonded to one oxygen atom. Nitrogen and carbon are found in other compounds, but not in water itself.
No, vinegar does not contain nitrogen. Vinegar is an acetic acid which is CH3COO
Yes, the atmosphere contains trace amounts of hydrogen gas, but it is primarily composed of nitrogen (78%) and oxygen (21%). Hydrogen gas is much less abundant in the atmosphere compared to nitrogen and oxygen.
Yes. Earth's atmosphere is about 78% nitrogen.
No, oxygen and nitrogen are gases that do not contain water. Water is made up of two hydrogen atoms and one oxygen atom. Oxygen and nitrogen are elements that exist as gases in the Earth's atmosphere.
Yes. Titan's atmosphere is mostly nitrogen.
No. Sugars are composed of carbon, hydrogen, and oxygen, but not nitrogen.
Oxygen. The early Earth's atmosphere was composed primarily of gases such as carbon dioxide, water vapor, nitrogen, and methane. Oxygen levels increased with the development of photosynthetic organisms.
All proteins contain carbon, hydrogen, oxygen and nitrogen. Most of them also contain sulfur, which is found in the standard amino acid residues cysteine and methionine (any given protein might not contain either of these, though it would be unusual).
No, monosaccharides are simple sugars that consist of carbon, hydrogen, and oxygen atoms. They do not contain nitrogen.
Nitrogen is a gas, it is found in the atmosphere. many chemicals contain it.
Nitrogen comprises of 78%. 22 % of the atmosphere does not contain nitrogen.

No. By definition, carbohydrates contain carbon, hydrogen, and oxygen.
