Vocabulary List (in order of appearance) Miscible Substance : Mixes without separation. Ethylene:A fundamental part of Ethanol is made up of Ethylene.Ethylene is a chain of two carbons joined by a double bond. There are two single bonded hydrogen atoms off of each carbon. Ethylene is a gas at 22¾ C. Ethylene’s chemical formula is C2H4. Alkene:Alkenes are chemical compounds in which there are carbon and hydrogen atoms arranged in a similar fashion. Alkenes are reactive with many substances because of the double bond between the carbons. Cracking: Inside the cracker, the hydrocarbons are heated by steam are passed over the hot alumina-silica gel, which is a catalyst. The catalyst provides a huge surface onto which the hydro-carbons break up into smaller, more useful hydrocarbons. Cracker: A cracker is a machine in the chemical plant used to break naptha.Inside the cracker, the hydrocarbons are heated by steam and are passed over the hot alumina-silica gel, which is a catalyst.The catalyst provides a large surface onto which the naphtha or hydro-carbon's crack(see vocab list)into smaller, more useful hydrocarbons napha (see vocab list). Catalyst: A catalyst increases the rate at which the reaction is completed, lowers the activation energy, is never consumed. Naptha: Napha is a chain of 8 to 12 carbons; a mixture of hydrocarbons that is a yellow liquid which condenses at temperatures between 70¾ and 160¾ C. Crack:
In the cracker the hydrocarbon’s bonds brake or crack.
