What element is not found in caffeine carbon helium nitrogen or oxygen?
helium
What does helium smell of?
No. Helium is one of the "inert" gasses, also called "noble gasses", because they undergo virtually no chemical reactions at all.Helium is odorless, tasteless, and based in its atomic number of 2 and atomic weight of 4, practically massless. Helium is very light, does not support combustion and does not support life. Helium is not poisonous, but if you are "huffing" from a helium balloon, you aren't getting any oxygen - and oxygen is one of the things that you need for life.Warning! Taking one or two breaths from a helium balloon is harmless, because there is plenty of oxygen still left in your system. But there is no oxygen in a helium balloon.Because it is completely inert, it does not bind at all with the body. So deep-sea divers use a mixture of helium and oxygen for their breathing tanks, because nitrogen in pressure causes "nitrogen narcosis" - the so-called "Rapture of the Deeps" - and oxygen is flat-out poisonous at high pressures. So divers use a mixture of 95% helium and 5% (or less!) oxygen for long-duration, high-pressure diving.
Which is a compound oxygen helium carbon dioxide nitrogen?
carbon dioxide
Is helium used for anything?
Helium is used to fill airships, balloons and helium is pumped into oxygen tanks for divers.
What are the gases found in the thermosphere?
Oxygen-20%Nitrogen-80%Helium-1%
Why is helium used in hot-air balloons when hydrogen is the lighter gas?
heliums ligther
Is oxygen gas also known for helium?
Oxygen is not known as helium. But a mixture of oxygen and helium is used in the oxygen cylinder for underwater diving.
Does helium dissolve into oxygen?
yes, helium does dissolve into oxygen.
Is helium oxygen?
No. Helium and oxygen are two different elements.
What is made from 15g of oxygen and 5g of helium?
There isn't a specific compound that can be made using 15g of oxygen and 5g of helium, as oxygen and helium do not readily react with each other to form compounds. However, both oxygen and helium are gases at standard conditions.
Which is lighter oxygen helium or nitrogen?
Helium
Can hydrogen and oxygen make helium?
Hydrogen an react with oxygen to form water and not helium
How are helium and oxygen different?
Helium is completely inert. Oxygen will react with many substances.
Is oxygen lighter than helium?
no. If it was, we would have oxygen balloons instead of helium balloons.
What is the mixture 15ml of oxygen and 5ml of helium?
A mixture of oxygen and helium is used in diving.
What are the gases making up helium and oxygen?
Helium is made up of helium and oxygen is made up of oxygen. Both helium and oxygen are elements, so they can't be broken down into anything simpler without breaking apart the atoms.
Why can't oxygen be changed into helium?
Oxygen has 8 protons, helium has 2 protons. To convert oxygen to helium, 6 protons has to be lost by nuclear disintegration which is not possible.
