Can a chemistry expert explain the following to me
please:
What is meant by the term "pi" bond cloud?
Why does hexane have a zig-zag shape?
What is an electrophile?
Thank you kindly
Hi
I wonder if you could help me with the following multiple choice questions:
[1] Which of the following does not have a dipole moment
a) H20 b)NH3 c)CO2 D)SF4 E)BRCL5
Are we just suppose to know that the answer is CO2 or is
there some simple way of working it out...
What are the applications and advantages/disdvantages of using gas
and high pressure chromatography? Why does the pharmaceutial industry
use chromatography?
Any info would be much appreciated
Thanx
Field and direction
When you say the field is "changing direction", do you
mean that its charge is changing, fluctuating
between positive and negative?
Are there any advantages of "alternating current"
over direct current, and why do we use it?

I am fairly new to chemistry, so this might seem like a stupid question, but I am still interested nonetheless. A burbon on the rocks exists because ice is less dense than water, but how can this be the case when the molecules in a solid are closer together?
We all know that heat energy can change the form of a substance. For example, ice into water. However, not all substances follow this simple rule; egg white, for example, congeals when heat is applied. Milk is another example. What is the reason for this?
When I was much younger, my teacher told me that electricity could be defined as "a flow of electrons". So when I turn on a light bulb or television set, what is actually happening inside? What is making the electrons move? A positively charged field perhaps? But how is the field created? Where...
Newbie here, so go easy. Electrons are negatively charged bodies orbiting around the nucleus, which contains the proton and the neutron. The net charge of the nucleus is positive, so why is there no attracton between the electrons and the nucleus?

Newbie here, so go easy. The electron contains a negative charge, the proton has a positive charge, so why is there no attraction between the two? Why doesn't the electron spiral towards the nucleus? The electron is an accelerating body, so why is no radiation being emitted?
Thanks
