Ethene is able to be collected over water because it is slightly soluble in water. The gas is made from ethanol vapor that is dehydrated by passing over a heated catalyst.
Oxygen can be collected over water. Water at the temperature of 25 degrees Celsius due to the pressure of the water temperature.
It can be collected by water displacement because it is NOT soluble in water, and so as a gas, it will displace the water.
because of dosplacement
hydrogen
No,it can't be collected
add water to ethyne in persence of murcuric salts(HgSO4) and Sulphuric Acid(H2SO4) will give ethanal
convert ethyne into ethane
Ammonia is collected in the laboratory by upward delivery and downward displacement of air....

Methane is not soluble in water and the density is also lower.
By combustion ethyne is transformed in carbon dioxide and water.

because hydrogen is collected by the upward displacement of air although it is 14.5 times lighter than air B)
a displacement beaker (canister) is used to determine volume of irregular objects. Water is put into the beaker up to the spout, and then an object is placed inside; the water that pours out is collected in a more accurate measurement device, this water is equal (or close to) the volume of the object.

Water displacement is when you put something in water and it gets displaced By Anne
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.
