Answer:
- the interplanar spacing for this set of planes is 0.0603 nm
- the atomic radius for a rhodium atom is 0.0707 nm
Explanation:
Part (a) the interplanar spacing for this set of planes
Applying Bragg's law
![d = \frac{n \lambda}{2sin \theta}](https://tex.z-dn.net/?f=d%20%3D%20%5Cfrac%7Bn%20%5Clambda%7D%7B2sin%20%5Ctheta%7D)
where;
d is the distance between set of planes
λ is the wavelength of monochromatic x-radiation = 0.0711 nm
n is the reaction order = 1
θ is the diffraction angle = 36.12°
![d = \frac{1(0.0711)}{2*sin(36.12)} \\\\d = 0.0603 nm](https://tex.z-dn.net/?f=d%20%3D%20%5Cfrac%7B1%280.0711%29%7D%7B2%2Asin%2836.12%29%7D%20%5C%5C%5C%5Cd%20%3D%200.0603%20nm)
Part (b) the atomic radius for a rhodium atom.
![d = \frac{a}{\sqrt{3^2 +1^2+1^2}} \\\\0.0603 = \frac{a}{\sqrt{11}} \\\\a = 0.0603 *\sqrt{11} \\\\a = 0.19999 nm](https://tex.z-dn.net/?f=d%20%3D%20%5Cfrac%7Ba%7D%7B%5Csqrt%7B3%5E2%20%2B1%5E2%2B1%5E2%7D%7D%20%5C%5C%5C%5C0.0603%20%3D%20%5Cfrac%7Ba%7D%7B%5Csqrt%7B11%7D%7D%20%5C%5C%5C%5Ca%20%3D%200.0603%20%2A%5Csqrt%7B11%7D%20%5C%5C%5C%5Ca%20%3D%200.19999%20nm)
Also, a = 2R√2
R = a/(2√2)
R = 0.19999/(2√2)
R = 0.0707 nm
Answer:
Volume of CaCl2 contained in the solution is 0.0198L
Explanation:
Explanation is contained in the picture attached.
A particle<span> is a minute fragment or quantity of matter. In the physical sciences, a </span>particle<span> is a small localized object to which can be ascribed several physical or a</span> chemical<span> properties such as volume or mass.</span>
The accepted concentration of chlorine is 1.00 ppm that is 1 gram of chlorine per million of water.
The volume of water is
.
Since, 1 gal= 3785.41 mL
Thus, ![2.29\times 10^{4} gal=2.29\times 10^{4}\times 3785.41 mL=8.66\times 10^{7}mL](https://tex.z-dn.net/?f=2.29%5Ctimes%2010%5E%7B4%7D%20gal%3D2.29%5Ctimes%2010%5E%7B4%7D%5Ctimes%203785.41%20mL%3D8.66%5Ctimes%2010%5E%7B7%7DmL)
Density of water is 1 g/mL thus, mass of water will be
.
Since, 1 grams of chlorine →
grams of water.
1 g of water →
g of chlorine and,
of water →86.6 g of chlorine
Since, the solution is 9% chlorine by mass, the volume of solution will be:
![V=\frac{100}{9}\times 86.6 mL=9.62\times 10^{2} mL](https://tex.z-dn.net/?f=V%3D%5Cfrac%7B100%7D%7B9%7D%5Ctimes%2086.6%20mL%3D9.62%5Ctimes%2010%5E%7B2%7D%20mL)
Thus, volume of chlorine solution is 9.62\times 10^{2} mL.
