If there is 4 of CH2CI2, then there is 8 of CI. There is already 2 in each one and there is 4 sets so 2x4=8

Calculate the unit cell edge length for an 87 wt% Ag- 13 wt% Pd alloy. All of the palladium is in solid solution, and the crysta
Goryan [66]

Answer:

Explanation:

   Since the crystal structure is FCC , every unit cell will have 4 atoms . If a be the edge length

average density = 4 x average atomic no / volume of unit cell x N

N is avogadro no or 6.02 x 10²³

average atomic no

= 100 / (87/107.9 +13/106.4) = 107.72

average density = 100 / (87/10.49 + 13/12.02)

= 10.667

10.667 = (4 x 107.72 )/ (a³x 6.02 x 10²³)

a³ = 4 x 107.72 / (10.667 x  6.02 x 10²³)

= 6.71 x 10⁻²³

a = 4.063 x 10⁻⁸ m

Trichloroacetic acid (CCl3CO2H) is a corrosive acid that is used to precipitate proteins. The pH of a 0.050-M solution of trichl
Nataly [62]

Answer:

Ka = 0.16

Explanation:

HClO₄ is a strong acid and it will dissociate completely to give hydrogen ion and the conjugate base.

The pH of HClO₄ will be calculated as:

pH = -log[H⁺]

pH = -log[0.04] = 1.4

The trichloroacetic acid is a weak acid and it will not dissociate completely.

The dissociation will be:

                CCl_{3}COOH---> CCl_{3}COO^{-} + H^{+}

Initial                     0.05                       0                         0

Change                -x                          +x                           +x

Equilibrium       0.05-x                     x                              x

Ka = \frac{[H^{+}][ClO_{4}^{-}]}{[HClO_{4}]}

As pH of the acid = 1.4 it means the concentration of hydrogen ion is 0.04.

Therefore

x = 0.04

Putting values

Ka = \frac{(0.04)(0.04)}{0.05-0.04}=0.16
