In preparation for Friday's quiz, I (Evan... not Mrs. McCluskey) will post the actual equations as I figure them out or someone sends them to me...Do you have a correct equation? are one/all of these on here wrong?...please e-mail me!

1. H+ (aq) + I (aq) + Cr2O72 (aq) ---> I2 (g) + Cr3+ (aq) + H2O (l)

2. OH (aq) + NH4+ (aq) ---> H2O (l) + NH3 (g)

3. Mg (s) + Ag+ (aq) ---> Mg2+ (aq) + Ag (s)

4. KClO3 (s)---> KCl (s) + O2 (g)

5. H+ (aq) + CO32 (aq) ---> CO2 (g) + H2O (l)

6. SO3 (s) + H2O (l) ---> H+ (aq) + HSO4 (aq)

7. Ba2+ (aq) + SO42 (aq) ---> BaSO4 (s)
