See the answer below
Explanation:
Ethane will burn in oxygen to form carbon dioxide and water according to the following balanced equation:
<em>From the equation, it means that for every one mole of ethane, three and a half moles of oxygen gas are required for complete combustion into carbon dioxide and water. Two and three moles of carbon dioxide and water would be produced respectively for every one mole of ethane that burns in three and a half moles of oxygen gas. </em>
This can be done by repeated exposure of the bacterial sample to the same antibiotic. This will enable you to see if the bacteria are able to survive in the presence of an antibiotic. The sensitive bacteria will die after some time of exposure. The resistant ones will survive and multiply, causing an increase in their numbers in the subsequent exposure with the antibiotic.
