i'm a new member here and im very happy to meet you in this club,i hope we will spend funy and important times here.Im also moderator for inorganic chemistry...
Balancing equations... Cu + 2AgNO3 --> 2Ag+Cu(NO3)2 We had to make an atom inventory and tell if it was balanced or not.. Elements reactants products ...
If the assigned equation is as you have written (which seems reasonable) and assuming the 3 in NO3 is a subscript, as is the 3 and 2 in (NO3)2) I honestly...
He must of been talking about this one because this is the only left that I got wrong... I had to balance this equation.. Fe+H20 --> Fe3O4+H2 my answer is... ...
Okay, now this one may have a problem. Could it be Fe2O3 rather than Fe3O4? Iron commonly exists in two oxidation states, +2 and +3, and oxygen typically has...
"FeO for +2 ... A valence of +8/3 per Fe atom would indeed be odd; But Fe3O4 is not odd at all! It's called "ferrosic oxide." Some of the Fe is +2, some is...
I would find it very strange for an instructor introducing the concepts of equation balancing to include such an 'exotic' species...ie, a mixture. The basic...
Dear colleagues: I have read in somewhere that we could hydrolyze protein by using sulfuric acid (30 %) to it's amino acid constituents. Any one who have an ...

May I know what carbon is known for its flexibility?...
... left ... I ... He said you shouldn't change the subscripts because if so you will have another reaction. This specific reaction should be read: 3Fe + 4H2O...
... summer ... I'm Christian (Costa Rica, BS on Chemistry). Analytical Chemistry will change your mind about how you work on the lab. It will take a lot from...
Hi everybody ! I'd like to determine free and total cyanide concentration in galvanic bath. I guess I will use titration method with AgNO3. Has anyone any...
Try titration in ammonia solution, this avoids formation of a silver cyanide precipitate at the end point of the titration. Use a 0.1mol litre-1 solution of...
... summer ... Hey Jason, I don't know how it is over there, but when I took analytical chem there was a lot of funny business going on. All the students who ...
I think that wont happen...after all...sum here are having problems in grades...i dont have to sabotage other Chemistry majors...the Pschology Department...
Hi Jason, I am sorry I didn't reply earlier. I am working in an analytical lab, and we use mainly HPLC and GC. I think these are the basic pieces of...
thanks carolyn...i really do hope i get a job as an analytical chemists...after all i am enjoying my laboratory experiments...next meeting we will be...

Hi Detergents are surface active substances. They lower the surface tension (gamma) of a liquid. A surfactant generally consists of a lipophilic and...
