You don't really see Antimony in a lot of everyday reactions (it is actually very rare in its metallic form), but you can actually burn it: 4Sb + 3O2-->2Sb2O3. If you are given 4.0 g Sb, how many grams of Sb2O3could you theoretically produce? You must show all work clearly and in detail to receive credit. All numbers immediately following elemental symbols should be understood as subscripts.

I have no idea how to do this haha. Any answers?
