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.

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.
