Question

In combustion analysis, the oxygen content of a substance is equal to the total oxygen in the CO2 and H2O collected in the absorbers.

Answer 1

Combustion is a technique that is used to evaluate the quantity of carbon, oxygen, hydrogen and sometimes nitrogen, and sulphur in compounds.It helps in evaluating the chemical formula of unknown compounds. Therefore, if a compound that has carbon and hydrogen is subjected to burning with oxygen using special combustion apparatus with oxygen all carbon is converted to carbon dioxide and hydrogen into water.
