Dear Students/Parents
We at 'Apex Institute' are committed to provide our students best quality education with ethics. Moving in this direction, we have decided that unlike other expensive and 5star facility type institutes who are huge investors and advertisers, we shall not invest huge amount of money in advertisements. It shall rather be invested on the betterment, enhancement of quality and resources at our center.
We are just looking forward to have 'word-of-mouth' publicity instead. Because, there is only a satisfied student and his/her parents can judge an institute's quality and it's faculty members coaching.
Those coaching institutes, who are investing highly on advertisements, are actually, wasting their money on it, in a sense. Rather, the money should be invested on highly experienced faculty members and on teaching gears.
We all at 'Apex' are taking this initiative to improve the quality of education along-with each student's development and growth.
Committed to excellence...

Sodium, magnesium, and aluminium react with oxygen to form ionic oxides. Sodium oxide and magnesium oxide are basic due to their oxide ions and react with water to form alkaline solutions. Aluminium oxide is amphoteric as it displays both acidic and basic properties, reacting with both acids and bases. Silicon dioxide does not react with water or acids due to its covalent bonding. Phosphorus and sulphur form acidic oxides that react with water to produce acids. Chlorine forms oxides that react with water to form acids or salts.
Chlorine exhibits several types of chemical reactions including oxidation, addition, substitution, and auto-oxidation/reduction reactions. It is a strong oxidizing agent that readily gains electrons and oxidizes many metals and nonmetals. Chlorine also directly combines with certain compounds through addition reactions and replaces atoms in other compounds through substitution reactions. When reacted with water, chlorine undergoes an auto-oxidation/reduction reaction forming hydrochloric acid and hypochlorous acid.
