Answer 2

Reaction of element 'Z' a trivalent ion with oxygen

Explanation:

• First lets define trivalent ion. Any atom, element, ion or chemical group with valency of three is known as trivalent ion.
• Here, element Z is a trivalent ion that means it has valency 3 and denoted as Z⁺³.
• When trivalent ion Z⁺³ reacts with oxygen an oxide is formed as a product.
• As to find the molecular formula of oxide, valency of trivalent ion and oxygen will be cross-multiplied.
• Valency of Z⁺³ is 3 and valency of oxygen is 2.
• So, required oxide formula will be Z₂O₃.
• The required balance chemical equation is -

           4Z⁺³  +  3O₂  →   2Z₂O₃
