The monomer of polyethylene is ethylene - H2C=CH2. {eth=2 carbons, ene=a CC double bond} Two methane - H2CH2 or H3CH - molecules condense to form ethane: H3C-CH3 + 2 H+. Another 2 H+ removal, or condensation, gives the -ene H2C=CH2. Polymerization of the -enes is the next step. Via another condensation reaction, a poly-eth-ene appears thusly: H2C=CH|HC=CH|HC=CH|HC=CH|HC=CH|HC... & etcetera.
The structural formula of hexane isCH3(CH2)4CH3For skeletal and other graphical representations, seehttp://en.wikipedia.org/wiki/HexaneC6H12 It is an alkane ,a hydrocarbon
There is no element with the symbol Hc. I have checked several periodic tables and find nothing I could imagine being identified this way.
HC
hydrogen carbonate
HC stands for High Cube
There is no element called Hc
No, you get to keep all your hc furni.
HC on an ultrasound means Head Circumference.
You can only buy HC furniture in habbo if you join the Habbo Club (HC). Joining HC costs around 30 coins per month, and will give you one free HC item per month. If you are not HC, you can still have the furniture, but you can not buy it from the catalogue.
Normally, HC gas is Hydrocarbon.
