The best answer is no bc the question ask "Would the two as yet undiscovered element A+1 and D+2" don't sound right
<span />
Hello,
I believe that your answer would be <span>B. water freezes
</span>Hope this helps
Explanation:
He used just the right amount of matter in water to get it to evaporate at a normal temperature and to condense into clouds for rain.
The first reaction from the scale Cl2 + BaF2 is <span>decomposition, remember! that H20 should be broken down.
The third one is </span><span> metal ion substitution
The last one is decomposition again.
</span><span>The second one is </span>H2 + Cl2 has been combined in order to synthesize <span> 2HCl, so that's the answer.</span>
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.
