) undergoes polymerization describes the formation of Teflon.
Explanation: Polymerization is the process in which small units called as
monomers join together repeatedly and forms a long chain macro-molecule called as
polymer.
In given question the monomer is Tetrafluoroethene because alkenes can undergo polymerization via Addition polymerization via following mechanism.
a) Free Radical Addition Reaction
b) Acid Catalyzed Addition Reaction
c) Base catalyzed Addition Reaction
The formation of
Teflon from Tetrafluoroethene is shown below,</span>
Answer:
Explanation:
f the mass of an object is 35 grams and it takes up 7 cm3 of space, calculate the density.

The concentration by mass means that the mass of solute in a given amount of solution. So for the a), the concentration should be 17/(17+183)*100%=8.5%. For b), the concentration should be 30/(30+300)*100%=9.09%.
