Answer: Option (A) is the correct answer.

Explanation:

Viscosity is defined as the ability of a liquid to resist its flow. When a substance has high viscosity then it is known as a viscous substance.

Also, more is the mass of a substance more will be its resistance to move from one place to another.

  • Mass of hexane is 86.18 g/mol
  • Mass of CH_3OCH_2CH_3 is 60.09 g/mol
  • Mass of CH_3CH_2OCH_2CH_3 is 74.12 g/mol
  • Mass of CH_3CH_2OH is 40.06 g/mol

Mass of HOCH_2CH_2OH is 62.07 g/mol

Therefore, out of the given options viscosity of hexane is the greatest.

Answer:

E. HOCH_2CH_2OH

Explanation:

Hello,

In this case, the tendency to form hydrogen bonds (bridges) provides a substance more viscous character as long as the intermolecular forces strengthen, in such a way, the substance with the highest tendency to form the aforesaid bonds is the ethylene glycol, HOCH_2CH_2OH, due to its two hydroxiles in its structure.

Best regards.

Paha777 [63]

Answer:

ionize

Explanation:

Acids are chemical substances that lose/donate their hydrogen ion (H+) when they react with water. This property of acids is termed IONIZATION. In a chemical reaction involving acids and bases, acids release their proton or hydrogen ion (H+) in the presence of water solutions to form a conjugate base, which is usually an anion.

For example, in the chemical reaction;

HX + H20 -------> X- + H30+

HX is the acid because it loses its electron to water and forms the anion, X-, which is the conjugate base. Hence, it can be said that acid HX ionizes in water.

Talja [164]

The mass of solute per 100 mL of solution is abbreviated as (m/v). Mass is not technically the same thing as weight, but the abbreviation (w/v) is also common. 262 grams of sucrose are needed to make 655 mL of a 40.0% (w/v) sucrose solution

<h3>Define Solute</h3>

A solute is a material that dissolves in a solution. The amount of solvent present in fluid solutions is greater than the amount of solute. The two most common examples of solutions in daily life are salt and water. Salt is the solute because it dissolves in water.

<h3>forms of ratios for product concentration or yield:-</h3>
  • w/v:- Weight by volume or weight per volume are the terms used. Any solid compound's concentration in a liquid can be calculated using it. It is measurable in gm/ml.
  • Weight by weight ratio is referred to as w/w.It is employed to determine the final yield of the compound obtained from the starting compound. as in —mg/—gm.

       It provides the real yield of the substance or item.

  • Volume/volume. It is used to specify a liquid's composition or percent in a liquid compound.

using w/v we can calculate the weight of sucrose:-

40.0% means 40 g sucrose/ 100 g solution

40.0g sucrose x (655/100)=grams of sucrose

262  grams of sucrose are needed to make 655 mL of a 40.0% (w/v) sucrose solution.
