Hi, i'm a new member at this group and i'd like to ask you a question..i'm preparing for my master degree in inorganic chemistry and i need some topics that...
Let say I recorded three times (9.54 s, 9.57 s, 9.51 s) and I wanted to average them. Should the answer be: (a) 9.547 (following basic sig fig rules exactly) ...
Not sure where you got 9.547 at? These are the rules, applied to each portion of the calculation. First part of the problem is addition: (report the least ...

Well I don't know where you got 9.547 from, because the average w/o counting sig figs is 9.540000. So with that said, you are correct that sig fig rules state...
What do we know? OK, fluorine gas of unspecified volume or quantity is cooled at constant volume from temperature T1=400K to T2=300K, the pressure starting at...
Hi AL, This may not be a very good answer. You get alot of equations in thermodynamics that look like this solubility one, because they are the solution of a ...
Hi Tunicia: As I had hoped, Nathan replied to you. There are a lot of us in this group pulling for you. If at first you don't understand, ask, ask again....
How you would report the average of these three results should depend on whether: (a) the three results are not to be added to but instead an average value to...
Hello Dalia: I suggest that you e-mail two persons to ask for their ideas. The first is Roald Hoffmann at Cornell University, rh34@.... The second is...
Thanks everyone for your help. This really raised my confidence in this class. This is the last chem class I need to graduate, well part 2 of this class also....
Well now that you've cleared that up... These students are going to have sig fig nightmares after this one... ... depend on ... as ... quote the ... results,...
does anyone know anything about chemistry that can explain to me how to solve these problems? yopu may also instant message me a mssassie_k on the yahoo I-M. ...
Heya Im just being really petty but i need to get this off my chest I HATE PHYS CHEM Mainly because for my second year end of year exams, which i guess you ...
From a different standpoint, I am a physical inorganic chemist (who is teaching p-chem and inorganic chem. this semester) who said the same thing about organic...
First of all, they would never use aluminum in an anti acid because aluminum is poisonous. It will kill zebra mussels in tiny concentrations. Also, if you...
mssassie, Looks like you have homework. My advice is to read the textbook for your class and study the examples. I will give you help on the first problem,...
Dan, Do you play a musical instrument? Well, if you do, or don't, you can conquer a piece, for example a movement in a concerto, by memorizing a small chunk,...
Hi, Thanks for your pointers. In fact there are two ways(and probably many more) to derive the integrated recrystallization formula from existing principles....
I suggest that you find yourself another university. Ask on the chemistry forums e.g. http://www.sciencemadness.org/talk/index.php , newsgroups and Yahoo...
Your inorganic and physical chemistry textbooks should have tables of the atomic weights of elements in them. Since you are given the reaction equations in...
hi all, can anyone kindly explain why the 3rd row TM in general form more stable metal-ligand bond than their 1st row counterparts? I thought the shapes of...
Hello I am interest in solid state battery and have some ideas about producing this kind of battery which would be cheap and has more capacity. (1.2 - 1.7...
My suggestion is the following: Don't worry about it. Remember that you are not alone in the course and therefore your mates will find it difficult also to...
