Re: Equilibrium Constant
Could you please explain more when to use Kc or Kp. Because don't all reactions when finding either K occur in gas phases?

Octet Exception
So do all elements in periods 2 and 13 don't have to follow the octet rule or just B and Be? How do you know which ones are an exception to the octet rule and which ones are allowed to have more than 8 electrons or less than 8?

Midterm 1 Monday Review
On Monday's review, Professor Lavelle did a practice problem that dealt with finding the molecular formula. We had solved the problem and got that the molecular formula was C9H11NO4, however, we did not divide by the smallest number. My question is, did we not divide by the smallest number because t...

Re: Leaving Balanced equations in half
We have to multiply the whole equation by 2 to eliminate the fraction! I'm not exactly sure what the professor said but he mentioned in class that we need to do this because molecules and atoms don't come in fractional parts. :)

Re: Order of molecules balanced
I don't think it matters which element you balance first. You start with the element with the lowest amount because it's easier as you go on and balance the rest, but if more than one element has the lowest number, it doesn't matter which one you do first. Like Natalie mentioned, it's helpful if you...
