If 6.00 g of carbon is burned completely, what volume of carbon dioxide gas is released at stp? a. 6.0 l b. 11.2 l c. 22.4 l d.134.4 l

The balanced chemical reaction for the combustion of carbon is,
                                C + O2 ---> CO2
6 grams of carbon is equal to 0.5 mols of carbon. This also corresponds to 0.5 mols of carbon dioxide. Using the ideal gas law through STP,
                                V = nRT / P
where R is the universal gas constant, 0.0821 L.atm /mol K, T is 273 K and P is 1 atm. Substituting the known values to the equation,
      V = (0.5 mols)(0.0821 L.atm/mol K)(273 K) / 1 atm = 11.2 L
Thus, the answer to the question is letter B.

The answer is not c

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.
