Witryna1 lut 2024 · Firstly, acetone is volatilized, then acetone vapour, which has a higher density than air (acetone: ρ = 2.4 g/l; air: ρ = 1.1 g/l, under standard conditions), descends through the tube and is ignited by the flame due to the mixture of air and acetone vapour created inside the tube. Activity 2: Investigating redox chemistry with … Witryna(which only has London dispersion forces) has a higher boiling point than acetone (which has dipole-dipole and London dispersion forces). Therefore, the London dispersion forces must be greater than the dipole-dipole forces in this case. 13. ΔH fus is the energy needed for water to go from a solid to a liquid and ΔH vap is the energy
