### Spectator

How do you know which chemical is the spectator in a equation? Are there certain qualities or signs that show it is a spectator?

### K A and K B

When dealing with titrations and given the Kb one can solve for the Ka and vise versa. When writing the constant for Kb the formula was products over reactants which I understand however I didn't understand why Ka was written as Reactants over products in today's example. Is Ka always written as rea...

### Re: What exactly are conjugate acids and base?[ENDORSED]

When solving for a problem dealing with acids and bases will it always state if it is dealing with either a strong or weak acid or base?

### Re: Chemical Equilibrium[ENDORSED]

What I find helpful is whichever side either (products or reactants of the equation) has an intial of 0 M is the side that will need X amount increase so a +X while the amount that has a known intial amount will be -X to decrease that side. I'm not entirely sure if this helps but it helps me

### Bonds

When do we use a double bond in a lewis structure rather than a single bond if there is resonance do we just write all the different Lewis structures ?

I couldn't agree more with Ben. Pacing myself is something I personally feel like I need to work on. As well as writing small is a great tip especially because writing in pen is preferred.

### Re: limiting reactant question[ENDORSED]

Is there a good way to see which is the limiting reagent because I'm still a bit confused on how to compare. I understand how to do the calculations until I get to the part where I compare the calculated moles with the moles from the balanced equation. As I am a bit confused can someone clarify how ...
