There is a magnet on the side of the flywheel that passes the engine's magneto, which causes the spark plug to ignite the gas in the piston. The flywheel is held onto the crankshaft by the flywheel key.
Triphenylmethanol (also known as triphenylcarbinol, TrOH) is an organic compound. It is a white crystalline solid that is insoluble in water and petroleum ether, but well soluble in ethanol, diethyl ether, and benzene.In strongly acidic solutions, it produces an intensely yellow color, due to the formation of a stable trityl carbocation.Many derivatives of triphenylmethanol are important dyes.n strongly acidic solutions, it produces an intensely yellow color, due to the formation of a stable trityl carbocation.

1 Ethanol is a very polar molecule due to its hydroxyl (OH) group, with the high electronegativity of oxygen allowing hydrogen bonding to take place with other molecules. 2  Ethanol therefore attracts polar and ionic molecules.3  The ethyl (C2H5) group in ethanol is non-polar. Ethanol is a very polar molecule due to its hydroxyl (OH) group, with the high electronegativity of oxygen allowing hydrogen bonding to take place with other molecules. 2  Ethanol therefore attracts polar and ionic molecules.
