Answer: In a compound with molecular formula
,the valency of Y and X are 2 and 3 respectively.
Explanation:
For formation of a neutral ionic compound, the charges on cation and anion must be balanced. The cation is formed by loss of electrons by metals and anions are formed by gain of electrons by non metals.
The given compound is
where X and Y combine and their oxidation states or valencies are exchanged and written in simplest whole number ratios. Thus the oxidation state or valency of X is 3 and that of Y is 2.
Answer:
The energy released from food was once energy from the sun that was captured by plants in the chemical process that forms plant matter (from air and water). Food provides animals with the materials they need for body repair and growth and the energy they need to maintain body warmth and for motion.

Explanation:
Oxides and their hydroxide counterparts made possible the industrial innovations we live in. Indeed, steel is a member of this family. Earth's crust contains them in vast quantities, making them the second most common element.
On a molecular scale, you would find that each oxygen atom is coupled with metal or semimetal atoms that fill in the gaps between them in oxide minerals. Oxides are divided into two groups: simple oxides, with a single metal or semimetal added, and complex oxides, where several metals can be incorporated into the molecule's structure. Hydroxides, on the other hand, are composed of metal ions attached to a highly reactive hydroxide ion (OH). Minerals formed by hydroxide are softer and less dense than oxides and usually form at lower temperatures.
