... Meaning: For every 2 mol of ethane, 7 mol of O2 molecules are consumed in the combustion THUS, producing 4 mol of carbon dioxide and 6 moles of water with the release of 3,170 kJ of thermal energy into the environment. This set of relationships can indicate, at a glance that: Twice as many moles of ...
