Answer:
The coordination number is 8
Potassium nitrate has an octahedral coordination structure
The balanced reaction is:
<span>4 Al + 3 O2
--> 2 Al2O3</span>
Each Aluminum atom wants to lose 3 electrons to become
isoelectronic with Oxygen. Each Oxygen on the other hand wants to gain 2
electrons. Since the reaction shows 6 Oxygen atoms in the product and each want
to gain 2 electrons, therefore a total of 12 electrons are transferred. Since
the problem ask for the electrons transferred per formula unit, hence:
<span>6 electrons (ANSWER)</span>
