The crystal structure of barium fluoride BaF₂ and magnesium fluoride MgF₂ is cubic and tetragonal lattice respectively.
There are difference between the cubic and tetragonal lattice of any crystal. For cubic lattice a = b = c and α = β = γ = 90⁰ and for tetragonal lattice a = b ≠ c and α = β = γ = 90⁰ (where a, b and c are the edge length of the lattice and α, β, γ angle of the crystal lattice).
The difference of the structure depends on the size of the ions present in the compound. In BaF₂, the ions are Ba²⁺ and F⁻. In MgF₂, the ions are Mg²⁺ and F⁻.
Although the size of the anion in both the crystal is same, there is a huge difference between the size of the cation, which affect the crystal lattice of the compound.
Answer:
to protect peoples teeth against cavities

Answer: Option (b) is the correct answer.
Explanation:
The given reaction is as follows.
In this reaction, potassium ions form bond with sulfate ions and results in the formation of potassium sulfate. Similarly, hydroxide ions combine with hydrogen ions to result in the formation of water.
Thus, we can conclude that it is a double replacement reaction occurs because potassium ions bond with sulfate ions to form a salt.
Answer:
A) XY3
In both of the atom, they want to have 8 valence electrons on the outer shell so they can become stable.
It will shrink, and eventually deflate because of the lack of kinetic energy.
