Meaning: For every 2 mol of ethane, 7 mol of dioxygen molecules are consumed in the combustion (a ratio of 2 to 7) This produces 4 moles of carbon dioxide, 6 moles of water and releases 3,170 kJ of energy from the bonding chemicals to the environment. This set of relationships can indicate, at a gla ...
