Solution

Ethyne:

  • Ethyne is a chemical compound with a molecular formula C2H2.
  • It is a colorless gas that is used as fuel.

Reaction of ethyne with Oxygen:

  • When ethyne reacts with a mixture of oxygen it produces carbon dioxide along with water.
  • The chemical reaction can be depicted as:

2HCCH(g)+5O2(g)4CO2(g)+2H2O(g)(Ethyene)(Oxygen)(Carbondioxide)(Water)

  • A mixture of ethyne and oxygen is used for welding as they both combine completely producing a clean flame.
  • When ethyne is burnt with oxygen a high temperature is attained due to the complete combustion of ethyne. Thus, it is used in welding.

A mixture of ethyne and air is not used for welding as no high temperature is being attained when ethyne is burnt with air and it produces a sooty flame.
