If you place a drop of cyclohexane onto a drop of water that is located on a glass surface, what would happen to the hexane and the water?
Isobutane is the fuel used in disposable lighters. The lighters' operation is dependent upon the butane's ability to vaporize and be ignited, and this depends somewhat upon the large pressure difference between the inside of the lighter
