MRSWAY Posted June 4, 2007 Share Posted June 4, 2007 Balancing equations! I found this on the internet, and i need it for my assignment. Is it correct? It's the egg + vinegar experiment. CaCO3 + 2 CH3CO2H ----> CO2 + H2O + Ca + 2CH3CO2 I also need to know what "CH3CO2" is? Thanks! Link to comment Share on other sites More sharing options...
ecoli Posted June 4, 2007 Share Posted June 4, 2007 CH3CO2 is the anion of acetic acid. Link to comment Share on other sites More sharing options...
Darkblade48 Posted June 4, 2007 Share Posted June 4, 2007 Technically, your reaction is correct, however, the ions will combine to form calcium acetate (of course, since this is in an aqueous phase, they should be Ca+2 (aq) and CH3COO- (aq), but then again, so would be the calcium carbonate and the acetic acid ) Link to comment Share on other sites More sharing options...

In addition, CaCO3 is not a soluble compound so that would not be aqeuous either. Link to comment Share on other sites More sharing options...
