Chemical Equilibrium and some Solution Problems
« on: March 10, 2008, 03:58:30 PM »
Okay, I have a few questions, first off:


1. In a solution of sodium chloride in water, the water would be classified as?

2. A__substance will be more likely to dissolve in a polar solvent than in a non-polar solvent.

3. The concentration of a solution in terms of moles solute per liter of solution is known as the?

                                                       AND

4. Increasing the pressure would shift the equilibrium to the___?
5. Increasing the temperature would shift the equilibrium to the___?
6. Adding a catalyst to the system would shift the equilibrium to the___?
7. Adding hydrogen to the system would cause the concentration of HI to___?


Now for 4, 5, 6, and 7, I think I have the answers,

4. right
5. left
6. niether
7. increase

I also have two more so....


1. Adding iodine vapor to the system would shift the equilibrium to the___?
2. Removing the hydrogen iodine as soon as it is formed would shift the equilibrium to the___?


For these I have...

1. left
2. right

Most of these questions are simple definitions, you can check your class notes, read your text book or, failing that, Google the web or read an English dictionary to get the whole answer.

The equilibrium questions are missing the setup, so we can't really check the question.  But you should show a little bit more of your own work, in any case.
Hey, I'm not judging.  I just like to shoot straight.  I'm a man of science.

Well these questions come from a study guide my teacher made me, and I did check my book so its hard because its a study guide for a test so they dont have any options for the answers, and in the book I cant find where they are. And I understand it seems I need more info but thats all thats on the study guide besides the other questions.

We do Socratic learning around here.  You ask a question, we give you a hint, we ask you a question that leads to the answer, you ask another question along those lines, back and forth, until you learn many new things.  We don't check calculations, or give complete answers or define words you have to look up, because that's cheating, and is dishonest.  And ultimately, works to your own disadvantage.

Now, listen. I'm going to give you one, so you can understand the point.

1. In a solution of sodium chloride in water, the water would be classified as?

In a solution, of NaCl in water, water is the solvent.  There, that's it.  If the same exact question shows up on the exam, you get it, free, without even reading your book.  I feel dirty Manjaro, knowing you have this advantage, because of me.  And you should too.

But, uh, what if this exact question isn't on the exam?  What is the NaCl called in this solution?  If you read your text, you'll know.  This is just the sort of trick an instructor will do on an exam, when they've given you a guide like this.

Im sorry I didnt want you to give me the anwser, but I was having trouble even understanding the question. I tried to find it in my book but I was haveing trouble locating what the question even meant.
