Oxygen is much more dense than ethyne. This is why a test tube full of ethyne would be held upside down so the ethyne doesnt escape into the air.

What element is less dense selenium or oxygen?
Oxygen is less dense.
Put the gases in order from least to most dense Oxygen carbon dioxide helium?
Helium, Oxygen, Carbon Dioxide (least to most dense)
Does more dense or less dense objects settle faster?
More dense.
Why is ethane and air mixture not used for welding?
When ethyne is burnt in air, it gives a sooty flame. This is due to incomplete combustion caused by limited supply of air. However, if ethyne is burnt with oxygen, it gives a clean flame with temperature 3000°C because of complete combustion. This oxy-acetylene flame is used for welding. It is not possible to attain such a high temperature without mixing oxygen. This is the reason why a mixture of ethyne and air is not used. Hope its fine with u !! all the best !!
What is the number of hydrogen atoms in a molecule ethyne?
The chemical formula of ethyne (acerylene) is C2H2 - two hydrogen atoms.
Which is most dense Steel or Oxygen?
Steel is more dense than oxygen.
What element is less dense selenium or oxygen?
Oxygen is less dense.
Why does less dense wood burn faster?
more space for air (oxygen)
What is mercury water gold and oxygen from densest to the least dense?
(most dense to least dense) gold, mercury, water, oxygen
Do you find more oxygen in lower altitude?
yes because the air is more dense at lower altitudes
How ethyne is converted into ethane?
convert ethyne into ethane
Why do apples float and pears sink?
Pears do not float in water because the pear is more dense than the water. The pear has a high water content, therefore making it more dense. For example, apples float because they are less dense than the water.
What gas is heavier ammonia or oxygen?
Oxygen (1,429 g/cm3) is more dense than ammonia (o,70 g/cm3).
What is the colour ethyne after combustion?
By combustion ethyne is transformed in carbon dioxide and water.
What were the results of the experiment in which a bottle of oxygen was placed over of air?
One bottle would have more pure oxygen then the other one, since oxygen is more dense then air, and will not rise into the atmosphere or combine with air quick
Why hydrogen gas collected by upward delivery?
Because hydrogen gas is less dense than air(mostly nitrogen and oxygen), and the less dense gas flows to go above the more dense(and escape the atmosphere).
Put the gases in order from least to most dense Oxygen carbon dioxide helium?
Helium, Oxygen, Carbon Dioxide (least to most dense)
