A tetrahedral site in a close-packed lattice is formed by four spheres at the corners of a regular tetrahedron. This is equivale

nt to placing the spheres at alternate corners of a cube. In such a close-packed arrangement the spheres are in contact and if the spheres have a radius r, the diagonal of the face of the cube is 2r. The tetrahedral hole is inside the middle of the cube. Find the length of the body diagonal of this cube and then find the radius of the tetrahedral hole.

Answer:

Now length of body diagonal of this cube = √3×√2×r =2.45r

Explanation:

a) length of body diagonal of this cube = √3×√2×r = 2.45 r

it can solved as following

length of body diagonal = √3a   (where a is edge length of cube)

length of face diagonal = √2a

But length of face diagonal = 2r

Therefore a = 2r /√2  = √2×r

Now length of body diagonal of this cube = √3×√2×r

Assuming acid strength relates directly to number of O atoms bonded to the central atom, rank H₂N₂O₂ [or (HON)₂]; HNO₃ (or HONO₂
Elenna [48]

For Less number of oxygen atoms will be less acidic. Therefore, the rank will be.... So there is 1 oxygen atom bonded to each of the 2 nitrogen atoms.

For HNO3 or {HONO}2. So there are 3 oxygen atoms bonded to the nitrogen.

For HNO2 or HONO. So there are 2 oxygen atoms bonded to the nitrogen.

Less number of oxygen atoms will be less acidic. Therefore, the rank will be...

HNO3>HNO2>H2N2O2

Acid strength is the tendency of an acid, symbolized by the chemical formula, to dissociate into a proton, and an anion, The dissociation of a strong acid in solution is effectively complete, except in its most concentrated solutions.

The strength of a weak organic acid may depend on substituent effects. The strength of an inorganic acid depends on the atom’s oxidation state to which the proton may be attached. Acid strength is solvent-dependent. For example, hydrogen chloride is a strong acid in an aqueous solution but is a weak acid when dissolved in glacial acetic acid.

How many distinct dichlorination products can result when isobutane is subjected to free radical chlorination?
Elenna [48]

Answer:

c. 3

Explanation:

Dicholorination of tertiary alkane ( i.e. isobutane) is a halogenation reaction which makes it possible to replace the alkyl functional group with halogenated chlorine.

When Isobutane is subjected to free radicals chlorination, three distinct dichlorination can be formed.

The mechanism of the formation of these products can be seen in the image attached below.
