So that we have the right answer once we do the addition
Say that I measure my self at 12 feet with one measuring stick, and go on with another measuring stick that tells me I'm 3 meters tall, if I added those, I would be at something like 15/46 or something like that. See that would be wrong. We would want the right denominator so that it could be easier and also correct.

Is kp or kc larger (both at 300 k) for the reaction 2 nh3(g) ⇀↽ n2(g) + 3 h2(g) ? 1. they are both the same. 2. kc is larger. 3.
fgiga [73]
The equation is 2 NH3 (g) ⇀↽ N2 (g) + 3 H2 (g) 
Difference in the number of moles delta n = ((3 + 1) - 2) = 4 - 2 = 2 
We have an equation Kp= Kc (R x T) ^ (delta n); R is constant and T = 300 K 
Kp / Kc = (R x T) ^2 Based on the temperature value (300 K), we can conclude that Kp is Larger.

Describe the three states of matter in terms of shape and volume
abruzzese [7]
Shape
A gas is shapeless all other things being equal. It will, if put in a container, occupy every part of the container.

A liquid could also be thought of shapeless. If put in a container, it need not occupy the entire container. It will occupy as much as its calculated volume will permit it to occupy.

A solid will only occupy its original shape.

Volume
A gas will occupy whatever container it is put in within limits. You cannot put a 72 mols of gas in a mm^3 container without some amazing ability to apply a lot of pressure.

A liquid will occupy a volume determined by its density and mass. In general liquids cannot be compressed. 

Whatever volume a solid has to start with, it will retain that volume all other things being equal.

This is actually very hard to describe.
