Burning Money Chemistry Demonstration Principle You soak a note in ethanol (alcohol) and it will burn when lighted‚ leaving the note untouched. This is because alcohol is more flammable‚ and burning alcohol causes it to vaporize‚ along with the water present in the solution. This removes heat from the note and prevents it from reaching its combustion point.

EXPERIMENT 2: SYNTHESIS OF ORANGE II (2-NAFTHOL ORANGE OBJECTIVE 1. To produce dye based to the coupling of diazonium. 2. To understand the characteristic of dye orange II. INTRODUCTION The first dye was introduced by William Henry Perkin on 1856. It can be produced by the coupling of diazonium sulfanilic acid with nafthol in alkaline solution.. This was the common method used to produce dye nowadays. In this experiment‚ dye produced was the orange II. Azo compound is compound that contain

Without Interface the computer cannot access the Media. Without the signal the electricity or copper wires cannot transmit information. Without Pattern there would be no established format for the signals. And timing lets the devices know when the pattern starts and ends.
