I just started reading this thread today, I am not doing so well. We are in week 5 of 10 already and I have failed 2 20 point quizzes and 1 100 point exam...... My teacher just sucks! We have subs for the next 2 weeks and they are so far so much better at teaching chemistry. I looked into dropping the course and retaking it next quarter BUT the only time that I would be able to take it has the same teacher, UGH! So I am looking to try to salvage my grade as much as I can. I have gotten all my lab points and he gives us extra credit(5 points at a time) for doing the questions at the end of the chapter. I have bookmarked the websites listed and also my library had the homework helper for chemistry so I placed a hold on it!!

Ill keep checking in here for advice/help.

Congrats Allieinaz! That's awesome. I just got home from taking my 1st chem exam today. I feel pretty good about it, but we'll see sometime next week probably. Now, on to the Anatomy exam on Monday! Looks like an exciting weekend ahead!

I am pretty sure I just bombed a organic chem quiz yesterday. It feels awful. I guess all we can do is just push on. I am going to have to make this class a priority in my life - which doesn't have much room for other priorities, but what can ya do? Half my class has already dropped. Our 1st big exam is next week. Rumor has it his 5 exams are all like finals. I am sure more will drop after that. I can't. This is my last transfer class and I must have it completed by June.

Have you tried to get a tutor? I signed up, but my school only has one O chem tutor and he is already booked. I did make it a point to go in and visit the professor during office hours. He is very nice, and seems reasonable - I just don't get this stuff! I wasn't great at general chem, either.

Hang in there!

Hey there Tonia!
Really glad that you came here and joined us! i'm sorry that you are having a rough time with your teacher. I really believe that it depends on who you have that will help you succeed. Are you currently taking General Chem or a higher level?
Definitely doing the extra credit assignments will help you in the end, i believe. I hope that you'll continue coming back here and asking for help. I know that I just started with General Chem but will try to help in anyway possible...good luck!

Thank you! Thank you!!! I'm very happy with the grade.....only 7 students out of 40 got an A, woo hoo......

I believe that if you feel pretty good about how you did on your exam, then you definitely did well. Crossing my fingers for you to get an A!

Great advice on the tutor! I agree with that definitely. I think as we start going on with the chapters, i'll need to sign up for a tutor as well. I know this sounds pretty basic compared to O chem but i'm having a difficult time seeing the difference between a heterogeneous mixture and a homogeneous mixture.....
The way my instructor stated was to think of a chocolate chip cookie....it's a heterogeneous mixture because you can "pick" the chocolate chips out.....HUH????? LOL.

Anyway have a fabulous weekend everyone!!! Remember....breathe.......

We got the chocolate chip cookie analogy too. I couldn't help but go "MMmmm Coookie" (ala Homer Simpson).

We have a test this coming Tuesday on polyatomic ions and covalent compounds. I'll pick up some ibuprofen tomorrow, think I'm going to need it. So far I have an "A" though...class avg is an 85.

Good luck, ya'll.

Too funny! Our professor always uses the analogy of raisin bran. We have to keep a sense of humor, right? Whatever works.

By the way everyone, another thing our professor gave us that seemed somewhat helpful was a neumonic for the diatomic molecules....I Bring Clay For Our New House: Iodine, Bromine, Chlorine, Fluorine, Oxygen, Nitrogen, and Hydrogen. I don't know about you guys, but every little thing that can help you remember a little easier helps!

How'd everyone's weekend go?

Did you all take the time and relax a little? Hope so!!

Here's to another week everyone!!

Help!@!!! can anyone help me balance this into a double displacement? Thanks!!

SnCl2 + LiOH

SnCl2 + LiOH

In double displacement think of the outer elements getting together and the inner elements getting together, then balancing the charges.

So:

SnCl2 + LiOH --> Sn(OH)2 + 2(LiCl)

SnCl2 + LiOH

The answer given above is wrong. Notice that Li is unbalanced still. (There are 2 Li on the product side, but only 1 Li on the reactant side.) The equation should read:

SnCl2 + 2LiOH ---> 2LiCl + Sn(OH)2

Also, don't put parentheses around LiCl on the product side.

Remember that in double-replacement/displacement reactions, you have to make sure one of them will precipitate, otherwise you mark it NR for No Reaction. In this case, the Tin(II) Hydroxide will precipitate.
