Homework Help: AP Chem

Posted by rose on Monday, October 10, 2011 at 9:22pm.

I'm having trouble balancing these two oxidation-reduction reactions that occur in a basic solution. Can anyone help? Please? The numbers after the formulas are subscripts and any with a minus sign means they are negatively charged (-1). Thanks!!

Al(s)+ MnO4-(aq)---> MnO2(s)+Al(OH)4-(aq)

NO2-(aq)+Al(s)-->NH3(g)+AlO2- (aq)
