Bromide gives away 1 electron (valency of 1) and Ca wants to gain 2 electrons (valency of 2) therefore 2 Br ions are needed
Answer:
B)The octet of carbon atom remains incomplete in the molecule.
Explanation:
The distance between the scattering planes in the crystal is d = 0.95 A°
<u>Explanation</u>:
The Bragg's equation is given by
2d sinθ = nλ
where,
d is the distance between the scattering planes in the crystal.
θ is the angle of diffraction.
n is the order of diffraction.
λ is the wavelength of X rays.
Given λ = 0.17 nm = 1.7 A°, angle = 62.5
2
d
sin(62.5) = 1
1.7 A°
d = 0.95 A°
The distance between the scattering planes in the crystal is d = 0.95 A°
