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>

Answer:
It is called Asterism.
Explanation:
It is Asterism because Asterism refers to a pattern of stars that are seen in night sky and are very distinctive and identifiable. These group of starts have patterns. It visually seen collection of stars and it's indicate their properties and the lines that connect the stars together.
