Is Vinegar an element or compound?

Acetic acid
Acetic acid/IUPAC ID
Carbon, hydrogen, and oxygen are the chemical elements in vinegar. This is because vinegar is a dilute solution of ethanoic acid (acetic acid) and water, and those are the chemical elements present in those compounds. Ethanoic acid has the formula CH3 COOH he formula while water has the formula H2 O.

Is air a homogeneous mixture?

Characteristics of mixtures One example of a mixture is air. Air is a homogeneous mixture of the gaseous substances nitrogen, oxygen, and smaller amounts of other substances.

Why do we need helium?

Because it is very unreactive, helium is used to provide an inert protective atmosphere for making fibre optics and semiconductors, and for arc welding. Helium is also used to detect leaks, such as in car air-conditioning systems, and because it diffuses quickly it is used to inflate car airbags after impact.

Can helium replace oxygen?

Because of its extremely low density, helium floats in air. (Practice this party trick in moderation, though: Helium replaces oxygen in the lungs and can kill you if you inhale enough.) Read on for more about this lighter-than-air gas, its amazing discovery story and all of its myriad uses today.
