Answer to Question #95340 in Organic Chemistry for Bruno

Question #95340

Explain the following:

i)Polyethylene exists either as a linear (straight-chain) polymer or as a branched polymer. Which is in high-density form? Explain.

ii)Draw how H2C=CH2 can be polymerized. What type of polymerization is method is used?
Calculate the energy required in joules to raise the temperature of 450 grams of water from 15°C to 85°C. (The specific heat capacity of water is 4.18 J/g/°C)

Expert's answer

I. Linear, because it is more compact, and it has more crystalic phase.

II. picture

III. (85-15)*4.18*450=131670 J=131.67 kJ
