Write balanced complete ionic equation for MgS(aq)+CuCl2(aq) = CuS(s)+MgCl2(aq)

oee [108]

The balanced chemical ionic equarion of MgS(aq)+CuCl2(aq) = CuS(s)+MgCl2(aq) would be as follows:

Mg2+ + S2- + Cu 2+ + 2 Cl- ==> CuS + Mg2+ + 2 Cl-

Therefore, the net equation would be:

Cu 2+ + S 2- ===> CuS

Hope this helps.

An x-ray beam with wavelength 0.170 nm is directed at a crystal. As the angle of incidence increases, you observe the first stro

xeze [42]

The distance between the scattering planes in the crystal is d = 0.95 A°

Explanation:

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 $\times$ d $\times$ sin(62.5) = 1 $\times$ 1.7 A°

d = 0.95 A°

The distance between the scattering planes in the crystal is d = 0.95 A°
