Vinyl

How do we name a compound with vinyl as a substituent. Would we not just treat that as a part of the parent chain of an Alkene?

What is Zero Order

I understand how to use the equations for zero order and how to derive them but I can't quite grasp the conceptual meaning of a Zero Order Reaction. If someone could describe it that would help out a lot.

Thanks

Conversions between Kelvin and Celsius

When converting Celsius to Kelvin do we add 273 or 273.15?

Another question,

Is Faraday's constant on the given periodic table incorrect? The page says F=96,4853. When I searched on google it came up with 96485.3 Which is correct?

Thank you

Re: Heat Capacity

How do phase changes affect the heat capacity? Is there a pattern to find one from the other or are they all different calculated values?

Re: Chemistry Jokes

Einstein, Newton and Pascal are playing a rousing game of hide and seek. Einstein begins to count to ten. Pascal runs and hides. Newton draws a one meter by one meter square in the ground in front of Einstein then stands in the middle of it. Einstein reaches ten, uncovers his eyes, and exclaims “New...

Re: Choosing the Best Lewis Structure

If I have a structure with a lone pair such as Chlorine Monoxide, ClO, how do I decide where the lone pair is supposed to go? Does the more electronegative of the two get the octet?

Thanks

Re: HW 1.57 Balmer series

Why are there different series; Lyman, Balmer Paschen? I read this section, but I did not understand why there wasn't only one since they all describe spectral lines measured from the Hydrogen atom.

Re: Which compound is more ionic?

Is it possible for a compound to be "more ionic" than another, or is it just that some ionic bonds are stronger than others?
