Answer: b. the number of electrons

Explanation: $4p^3$

1. 4 is the principal quantum number which describes the size of the orbital. It is represented by n.

2. The electrons are present in p sub shell also called as azimuthal quantum Number: This quantum number describes the shape of the orbital. It is represented as 'l'. The value of l ranges from 0 to (n-1). For p orbital, l=1.

3. The p subshell contains 3 electrons.

Be sure to answer all parts. find the molar solubility of bacro4 (ksp= 2.1 × 10−10) in (a) pure water × 10 m (b) 1.6 × 10−3 m na

Vlad [161]

A) in pure water :

by using ICE table:

According to the reaction equation:

BaCrO4(s) → Ba^2+(aq) + CrO4^2-(aq)

initial 0 0

change +X +X

Equ X X

when Ksp = [Ba^2+][CrO4^2-]

by substitution:

2.1 x 10^-10 = X* X

∴X = √2.1 x 10*-10

∴X = 1.4 x 10^-5

∴ the solubility = X = 1.4 X 10^-5

B) In 1.6 x 10^-3 m Na2CrO4

by using ICE table:

According to the reaction equation:

BaCrO4(s) → Ba^2+(aq) + CrO4^2-(aq)

initial 0 0.0016

Change +X +X

Equ X X+0.0016

when Ksp = [Ba^2+][CrO4^2-]

by substitution:

2.1 x 10^-10 = X*(X+0.0016) by solving for X

∴ X = 1.3 x 10^-7

∴ solubility =X = 1.3 x 10^-7
