A note from the emergency broadcast system

Three questions. One from each section.

g.                  18.3g HBr to formula units

5.            KOH and HCl react to produce KCl and H2O. 
a) If you start with 75.0g of potassium hydroxide and excess HCl, how many grams of potassium chloride would be formed?
b) (H) If you react the KOH with 50g of HCl, how many grams of potassium chloride would be formed? Which product is the limiting reactant? How much of the reactant in excess would be left over?

f.                  85.6% C, 14.4% H [molecular weight of 42.1g]

I'm pretty sure I can't actually give better hints than this

Give me your hand.

Vertigo is a type of dizziness [cool word--two z's!!]. It's caused by dysfunction in the inner ear (the wiki article is here).

Well, anyway...I'm you get vertigo when you watch this video? Double click to go the source. It's pretty cool stuff, and a job that I think I'd pass on. Alright, I do want to throw a paper airplane off of it.

Seriously. A New Form of Life.

And here it is. Instead of using phosphorus, it substitutes arsenic. Wow! Links are here at Huffington Post, and here at NASA.

This is a pretty big deal. So, read all about it.

Come on, click. See. Read. This is good stuff.

Update: maybe not. stay tuned to this bat channel for more information as it becomes available. Again, if this was an emergency, you'd have bee where to go and what to do...because clearly, the guy telling you is hoping you'll wait around, so they can get a head start. I'm just sayin'.
