Calculate the amounts requested if 3.30 mol fe2o3 completely react according to the following equation. fe2o3 + 2al --> 2fe + al2o3 < br />
a. moles of aluminum needed< br />
b. moles of iron formed < br />
c. moles of aluminum oxide formed

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.
