If a certain compound has a formula A3B2, what is the valency of elements A and B?
Answers
Explanation:
The valency of element A is 3, that is, oxidation state of element A is A^{3+}. The valency of element B is 2, that is, oxidation state of element B is B^{2-}.
This means that 2 atoms of A reacts with 3 atoms of B.
Therefore, the reaction will be as follows.
Answer:
The valency of element A is 2 and that of element B is 3.
Explanation:
The given compound is A₃B₂. This means that three atoms of element A and 2 atoms of element B combine to form the compound.
The valency of element A is satisfied by combining with 2 atoms of element B.
The valency of element B is satisfied by combining it with 3 atoms of element A.
We know that while forming a compound, the valencies of the elements are cross-multiplied. So, to get a compound A₃B₂, the valency of element A must be 2, and the valency of element B must be 3.
Element: A B
Valency: 2 3
The reaction will be as follows:
3A + 2B → A₃B₂
Therefore, the valency of elements A and B is 2 and 3 respectively.
