2004-09-28 [Firenze]: same here
2004-10-29 [digimatt]: :)
2004-10-31 [Firenze]: Hello, Howz everyone?
2004-11-13 [footballgal]: hey yall how r yaz send me a massage or something peace out
2004-12-11 [Firenze]: Thanks [Sunrose] for the update and keep smiling as you are the most hard working person I know other than [font]
2004-12-11 [Sunrose]: *^___________^
2004-12-11 [Firenze]: I'm glad you like the comment ^_^
2004-12-11 [Sunrose]: yea I did hehehe!
2004-12-11 [Firenze]: ^_^
2004-12-19 [syagre]: ...can't believe some folks made a wiki about Chemistry around here... CHEMISTRY SUCKS !!! (I just drug myself sniffing thiophene) any specialist of adsorption and/or breakthrough curves is welcome to send me a message...
2004-12-23 [Firenze]: If you thinks chemistry sucks then why leave a message and any you get high on pure alcohol (Ethanol) quicker than you do thiophene.
2005-02-20 [NyMphEtAmIne GiRl]: i need some help in chem plz helpme
2005-02-28 [Tears of the Dead Star]: How do you do word equations for example zinc + lead (II) nitrate yield zinc nitrate + lead ?
2005-02-28 [Jivo]: Zn(s)+Pb(NO3)2(aq) --> Zn(NO3)2(aq) + Pb(s). Does that answer your question?
2005-02-28 [Tears of the Dead Star]: Wow... thanks : )
2005-03-12 [Tears of the Dead Star]: How do u do Complete ionic equations and Net Ionic Equations??
2005-03-12 [Jivo]: I don't think I completely understand your question, could you maybe provide an example problem?
2005-03-12 [Tears of the Dead Star]: I have several questions that Im supposed to figure out, in both kinds of equations... Na(2)SO(4)+BaNO3(2), K(2)CrO(4), stuff like that... Im supposed to put them into Moleculer eqautions, Complete ionic equations and Net Ionic equation
2005-03-12 [Tears of the Dead Star]: well ok... three kinds of equations.... I almost forgot about the molecular : (
2005-03-14 [Jivo]: Well, I'm a bit puzzled about what actually is being asked of you to do. I reckon you have to make solvation equations and a equation of a reaction in aquaeous media. Things like Na(2)SO(4) solve very good in water (almost all sodium salts do) so you get Na(2)SO(4) --> 2Na(+) + SO4 (2-). BaNO3(2) --> Ba(2+) + 2 NO3(-). K2CrO4 --> 2K(+) + CrO4(2-). And about the reactions in aquaeous media, those are a bit more difficult. You have to figure out which combination of ions will form a non-soluble (sp?) salt, that salt is formed. The other ions remain in the solution. Example: 2NaI + PbSO4 --> 2Na(+) + SO4(2-) + PbI2 (the salt lead(II)iodide isn't soluble in water)
2005-03-14 [Tears of the Dead Star]: wow ur good : ) thank you soo much
