C3H8 +02 → CO2 + H20 O Single Replacement
O Decomposition
O Double Replacement
O Combustion

Is a logical series of steps

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.
