Hello, Habiba,
There isn't much information here, but I am assuming the question concerns the enthalpy of a certain reaction. That could be expressed in several units, one popular unit is J/mole. If I assume the -138 is Joues. then the q for this reaction is = -(138J/3moles), or -46J/mole.

Ch4+2o2____ co2+2h2o so the heat released from combustion of 3mol of methane delta h=-126 (2670 kj/-2670kj) Thanks03/30/21
