Answer: option a. nuclear fusion.

Nuclear fusion is the union of atoms leading to a new bigger atom.

Nuclear fission refers to the split of atoms.

Nuclear energy is the energy resulting from nuclear reactions.

Answer: The correct answer is option (a).

Explanation:

Nuclear fission and nuclear fusion both are types of nuclear reactions.

In nuclear fission , splitting of a large atom into smaller atom takes place with release of energy in large amount.

In nuclear fusion , two small atoms combine with each other to form a large atom with release in energy in large amount

The energy released in both the nuclear fission and fusion is termed as nuclear energy.

Hence, the correct answer is option (a).

Amphetamine (C9H13N)(C9H13N) is a weak base with a pKbpKb of 4.2. You may want to reference (Pages 710 - 713) Section 16.8 while
Soloha48 [4]

Answer:

pH = 10.38

Explanation:

  • C9H13N ↔ C9H20O3N+  +  OH-

∴ molar mass C9H13N = 135.21 g/mol

∴ pKb = - log Kb = 4.2

⇒ Kb = 6.309 E-5 = [OH-][C9H20O3N+] / [C9H13N]

∴ <em>C</em> sln = (205 mg/L )*(g/1000 mg)*(mol/135.21 g) = 1.516 E-3 M

mass balance:

⇒ <em>C</em> sln = 1.516 E-3 = [C9H20O3N+] + [C9H13N]......(1)

charge balance:

⇒ [C9H20O3N+] + [H3O+] = [OH-]; [H3O+] is neglected, come from water

⇒ [C9H20O3N+] = [OH-].......(2)

(2) in (1):

⇒ [C9H13N] = 1.516 E-3 - [OH-]

replacing in Kb:

⇒ Kb = 6.3096 E-5 = [OH-]² / (1.516 E-3 - [OH-])

⇒ [OH-]² + 6.3096 E-5[OH] - 7.26613 E-8 = 0

⇒ [OH-] = 2.3985 E-4 M

∴ pOH = - Log [OH-]

⇒ pOH = 3.62

⇒ pH = 14 - pOH = 14 - 3.62 = 10.38

Explain the regiochemical outcome for chlorination of bromobenzene.
Wittaler [7]

Answer:

See explanation

Explanation:

In a chemical reaction, a particular reaction path may be favoured due to the fact that it is energetically more favourable(lower energy sigma complex is formed).

The more the resonance structures produced in a particular reaction pathway, the more energetically favourable it is.

In the chlorination of bromobenzene, ortho attack and para attack are preferred because each of these pathways involves a sigma complex with__4________resonance structures. Attack at the meta position involves formation of a sigma complex with only____3_______ resonance structures. The reaction will proceed more rapidly via the_____lower_______ energy sigma complex, so attack takes place at the ortho and para positions in preference to the meta position.
