Chem. exam tomorrow! Question about my equations being correct.
« on: May 28, 2007, 11:08:17 AM »
I've got a few questions.   ???

1. Is acetic acid the same as white vinegar?               

2. Is this correct?   When carbonic acid (hydrogen carbonate) is formed, it immediately decomposes. Write the balanced equation for this reaction.
My answer: 2HCO3-->2H+2CO3

3. Write a balanced equation for the mixing of calcium carbonate and acetic acid. This is a double displacement reaction. (I have NO clue how to do this)


Thank You!!!

Ethanol has the similar relationship to wine as acetic acid has to vinegar.
