So i am confused with this question and i need a place to start the problem.

Mercury and bromine will react with each other to produce mercury (II) bromide:
Hg (l) + Br2 (l) => HgBr2 (s)
A. What is the mass of HgBr2 can be produced from the reaction of 10.0 g Hg and 9.00 g Br2?
B. What mass of which reagent is left unreacted?

You don't have to give the answers, but can someone walk me through or help me start the question? :] thanks!

The organic solvent is used on a baseified aqueous solution with alkaloids. Later the organic solvent is seperated and titerated with sulfuric acid to produce alkaloid salts. From here how should the salts be removed from the organic solvet? Would tolulene be better over Xylene or vice-versa? Thanks!

This stuff really works just like the commercials. My gf would not let me out of the house this morning after I put on my spray. They don't advertise it contains pheromones but it must contain some pheromone-like ingredient.
