(12) Show the formation of the ionic compound Aluminum Oxide: i)use either
1 answer:
Aluminium oxide is a ionic compound with formula of Al2O3.
<h3><u>Explanation</u>:</h3>Aluminium belongs to the group 3 and has the atomic number of 13. So it has an electronic configuration of [Ne] 3s2 3p1. So its valence shell has 3 electrons which can be donated to form the Al3+ cation.
On the other side, oxygen belongs to the group 16 with atomic number of 8. It has the electronic configuration of [He] 2s2 2p4. So it has 6 electrons in its outermost shell which can receive another 2 to form the stable octet.
So both aluminium and oxygen reacts to form the aluminium oxide whose formation is shown in the diagram. Both the images are taken from Google.

Answer and explanation:
The attached figure shows five different structures for the chemical formula C4H5O5, but only one of these structures represent the malic acid.
Malic acid is a dicarboxylic acid, this means malic acid has two
-COOH groups. Also, malic acid is a secundary alcohol, which means it has a R2-C-OH group.
-Structure A has two carboxylic groups, but it doesn´t have a secundary alcohol.
-Structure B doesn´t have any caborxylic group.
-Structure C has two carboxylic groups and it is a secundary alcohol. Structure C is the Malic acid
