What is the change in enthalpy in kilojoules when 3.24 g of CH3OH is completely reacted according to the following reaction 2 CH3OH -->4 CH4 + O2 ∆H =252.8 Kj

12.78 kJ

Explanation:

The correct balanced reaction would be

Mass of methanol =

Moles of methanol can be obtained by dividing the mass of methanol with its molar mass

Enthalpy change for the number of moles is given by

The change in enthalpy is 12.78 kJ.

geosphere and hydrosphere.

this is because the geosphere has to do with geological events, while the hydrosphere controls all water on earth.
