How do molecules of ethene combine together to form a poly(ethene) molecule?

AI Thread Summary
Molecules of ethene combine to form poly(ethene) by breaking their double bonds, allowing the unpaired valence electrons to bond with other ethene molecules. This process creates a long chain of carbon atoms, resulting in the polymer known as polyethylene. The discussion highlights the importance of understanding the breaking of double bonds in polymerization. A video linked in the conversation aids in visualizing this process. Overall, the explanation clarifies the mechanism of ethene polymerization effectively.

hi,

i need to explain how molecules of ethene combine together to form a poly(ethene) molecule?

would it be because the double bond is broken and 2 bonds them placed on the outside of the Carbons (C)?

if this is not correct could someone please let me know where I am going wrong!

thanks!

Yes, it goes somewhat on the way you described. The double bond of ethene (ethylene) molecules are broken and the unpaired valence electron(s) get bounded with those of an other group.

See: http://en.wikipedia.org/wiki/Polyethylene

See this video, it is cute!

Thread 'Rolling without slipping on a curved surface'

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
