Answer : The correct answer is C) protons

The positively charged particle found in nucleus are protons . They need to be kept separated as if the protons of two different particles are brought together , due to same charge they will repel each other.

If electrons are considered , they carry negative charge on them and they are present outside nucleus . Neutron have no charge on it although they are present in nucleus .

Quarks are present in both neutrons and protons . They carry both positive and negative charges .

Hence we can say protons are the positively charges particles which need to be separated .

The process by which the movement of internal bonds converts one type of what organic compound into another is
nevsk [136]

Answer: It's is called Reaarrangement

Explanation:

Rearrangement is a chemic reaction in which an atom or group of atoms bond migrate from one carbon atom to another. The movement involves two adjacent atoms and move over a large distance. It is important in functional group transformation.

Reaarrangement can be classified based on the atom or group of atoms it migrate.

Nucleophilic rearrangement which involves the migration of atoms with electron pairs.

Electrophilic migration involved the migration of atom or groups without electron pair.

Free radical involves the atom or group of atoms moving with a lone pair of electron.

Calculate the concentration of IO−3 in a 1.65 mM Pb(NO3)2 solution saturated with Pb(IO3)2 . The Ksp of Pb(IO3)2 is 2.5×10−13 .
lara31 [8.8K]

Answer:

See explaination

Explanation:

1) Pb(NO3)2 => Pb2+ + 2 NO3-

[Pb2+] = [Pb(NO3)2] = 7.56 mM = 7.56 x 10-3 M

Pb(IO3)2 <=> Pb2+ + 2 IO3-

Ksp = [Pb2+][IO3-]2 = 2.5 x 10-13

7.56 x 10-3 x [IO3-]2 = 2.5 x 10-13

[IO3-] = 5.75 x 10-6 M ≈ 5.8 x 10-6 M

(2) [Pb2+] = 1.7 x 10-6 M

Ksp = [Pb2+][IO3-]2 = 2.5 x 10-13

1.7 x 10-6 x [IO3-]2 = 2.5 x 10-13

[IO3-] = 3.83 x 10-4 M

[IO3-]from Pb(IO3)2 = 2 x [Pb2+]

= 2 x 1.7 x 10-6 = 3.4 x 10-6 M

[IO3-]from NaIO3 = [IO3-] - [IO3-]from Pb(IO3)2

= 3.83 x 10-4 - 3.4 x 10-6

= 3.80 x 10-4 M

NaIO3 => Na+ + IO3-

[NaIO3] = [IO3-]from NaIO3

= 3.80 x 10-4 M ≈ 3.8 x 10-4 M
