1) The conversion of ethanol to ethanoic acid an oxidation reaction because there is an addition of oxygen.
 
2) Ethyne burns in air with a sooty flame because of incomplete combustion caused by the limited supply of air. However, ethyne burns in oxygen with a clean flame with a temperature of 3000°C because of complete combustion.This oxy-acetylene flame is used for welding.Such a high temperature cannot be achieved without mixing oxygen.Therefore, a mixture of ethyne and air is not used for welding.
