explain why the crystal structure of barium fluoride, BaF2, differs from that of magnesium fluoride, MgF2
Leto [7]

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.

Chlorofluorocarbons such as CCl2F and CCI,F, have been linked to ozone depletion in Antarctica. In 1994, these gases were found
Ilya [14]

Answer:

a) molarity of CCl3F = 1.12 × 10^-11 mol/dm³

Molarity of CCl2F2 = 2.20 × 10^-11 mol/dm³

B) molarity of CCL3F = 7.96 × 10 ^-13 mol/dm³

Molarity of CCl2F2 = 1.55 × 10^-12 mol/dm³

Explanation:

Using the ideal gas equation:

PV = nRT
