Gaaffii 1

Which of the following is NOT a conjugate acid-base pair?

  1. A.HNO3/NO3−\mathrm{HNO_3/NO_3^-}
  2. B.H2SO4/HSO4−\mathrm{H_2SO_4/HSO_4^-}
  3. C.NH3/NH2−\mathrm{NH_3/NH_2^-}
  4. D.H3O+/OH−\mathrm{H_3O^+/OH^-}
Deebii fi ibsa ilaalaa

Deebii: D H3O+/OH−\mathrm{H_3O^+/OH^-}

Maaliif

A conjugate acid-base pair must differ by exactly one proton (H+). H3O+ and OH- differ by two protons, as the conjugate base of H3O+ is H2O, and the conjugate base of H2O is OH-.

Gaaffii 2

Which of the following is correct?

  1. A.1L=1dm3\mathrm{1L=1dm^3}
  2. B.1L=10dm3\mathrm{1L=10dm^3}
  3. C.10L=1dm3\mathrm{10L=1dm^3}
  4. D.1L=1m3\mathrm{1L=1m^3}
Deebii fi ibsa ilaalaa

Deebii: A 1L=1dm3\mathrm{1L=1dm^3}

Maaliif

By definition of metric units of volume, 1 liter (L) is exactly equal to 1 cubic decimeter (dm^3).

Gaaffii 3

Commercially, liquid vegetable oils are converted to solid fats such as margarine by:

  1. A.Hydrogenation
  2. B.Hydration
  3. C.Saponification
  4. D.Oxidation
Deebii fi ibsa ilaalaa

Deebii: A Hydrogenation

Maaliif

Catalytic hydrogenation adds hydrogen across carbon-carbon double bonds in unsaturated liquid vegetable oils, raising their melting point to produce semi-solid or solid fats like margarine.

Gaaffii 4

What is the chemical name for Aspirin?

  1. A.Acetyl salicylic acid
  2. B.Salicylic acid
  3. C.Methyl salicylate
  4. D.Sodium salicylate
Deebii fi ibsa ilaalaa

Deebii: A Acetyl salicylic acid

Maaliif

Aspirin is the common trade name for acetylsalicylic acid, which is synthesized by the acetylation of salicylic acid.

Gaaffii 5

Which of the following statement(s) is (are) true of an ideal liquid-liquid solution? I. It obeys PV = nRT II. It obeys Raoult's law III. Solute-solute, solvent-solvent, and solute-solvent interactions are very similar. IV. Solute-solute, solvent-solvent, and solute-solvent interactions are quite different.

  1. A.I, II and III
  2. B.I, II and IV
  3. C.II and III
  4. D.II and IV
Deebii fi ibsa ilaalaa

Deebii: C II and III

Maaliif

An ideal solution obeys Raoult's law over all concentrations because the intermolecular forces between unlike molecules (solute-solvent) are identical in strength to those between like molecules (solute-solute and solvent-solvent). PV = nRT is the ideal gas law, not applicable to liquids.

Gaaffii 7

In a reaction, A + B →\rightarrow product, the rate is doubled when the concentration of B is doubled, and the rate increases by a factor of 8 when the concentrations of both the reactants (A and B) are doubled, the rate law for the reaction can be written as:

  1. A.Rate = K[A][B]
  2. B.Rate = K[A][B]2^2
  3. C.Rate = K[A]2^2[B]
  4. D.Rate = K[A]2^2[B]2^2
Deebii fi ibsa ilaalaa

Deebii: C Rate = K[A]2^2[B]

Maaliif

Doubling [B] doubles the rate, meaning the reaction is first-order with respect to B. Doubling both [A] and [B] increases the rate by a factor of 8 (2^x × 2^1 = 8), which gives x = 2, so the rate law is Rate = k[A]^2[B].
