chem homework
lilitalienboi16:
I'm doing a rediculous amount of chem homework atm which is due this thursday. I've been working on it for the past 3 hours.
My current question [not that you care :P] is;
Ammonia can be generated by heating together the solids NH4Cl and Ca(OH)2. CaCl2 and H2O are also formed.
(a) If a mixture containing 33.0g each of NH4Cl and Ca(OH)2 is heated, how many grams of NH3 will form?
First one to get the answer gets a free internet cookie! Ready..set... GO!!
:D

The answer to part A is;
10.5G, did you get it? Good job if you did! :)
lilitalienboi16:
(B) Which reactent remained in excess and in what mass?
Answer to be posted soon!
The Answer is; 10.1g of Ca(OH)2 remain in excess.
Did ou get it? If you did, pat yourself on the back! Haha, that one was a tough one. I racked my brain over it for a good 15 minutes, lol. Yea.. this his how long my chem homework takes, imagin doing like 30-40 problems of those for homework in one night. AHH! LOL

Well, I was about to answer the last one but humm, I will need more time on the second one.

Haha, having fun are we? Here's another one. It's much easier.
In the reaction 1.80 mol of CCl4 with an excess of HF, 1.55mol of CCl2F2 is obtained.
CCl4 + 2HF ----> CCl2F2 + 2HCl
What is the actual yield?
Ill give a few minutes to answer this before i post the answer. So those who want to try can. It's very simple, don't make it complicated!
