How many moles of O2 to produce 1.00 mole of CO2?(using dimensional analysis) use the given reaction - 2 CO + O2 —> 2 CO2

Answerδh > 0explanationc₆h₆  (s)  → c₆h₆ (l)if you are changing it from a solid to a liquid, you are pretty much melting the solid. this requires heat energy. therefore, the reaction is endothermic (takes in energy); the system enthalpy increases as the reaction proceeds: δh > 0.
