How many grams of carbon dioxide would be produced if we use 35 grams of methane in the reaction below? CH4 +2O2 Co2 + 2H2O

That is a lot of moles that you have

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.
