Multiple choice chemistry mix and separate dry methods of separation process of separating components of a mixture method of separation

Winnowing is the process used to separate particles of ____________.

  1. heavier and lighter weight

  2. only two heavier particles

  3. only two lighter paticles

  4. None of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The process of separation of lighter particles from heavier particles; with the help of wind; is called winnowing. This method is used for separating grains from husk.
Hence option A is correct.

Multiple choice chemistry mix and separate different types of mixtures homogenous and heterogenous mixtures all about mixtures

Salt, sugar, and many other substances dissolve in water to form :

  1. homogenous mixture

  2. heterogenous mixture

  3. Ionic compound

  4. molecular compound

A Correct answer
Explanation

A mixture is a material system made up of two or more different substances which are mixed but are not combined chemically. A homogeneous mixture is a type of mixture in which the composition is uniform and every part of the solution has the same properties. Salt, sugar, and many other substances dissolve in water to form homogeneous mixtures.

Which of the following is a homogeneous solution?

  1. Muddy water

  2. Bread

  3. Concrete

  4. A solution of sugar in water

D Correct answer
Explanation

The solution in which the concentration of solute is the same in every part of the solution is known as a homogeneous solution, sugar is completely soluble in water and forms homogeneous solution.

A true solution is a homogeneous mixture of solute and solvent. Chalk powder in water is a heterogeneous mixture. Hence chalk powder is not a true solution.

  1. True

  2. False
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

A true solution has solute completely dissolved in the solvent. In case of chalk powder, it does not completely dissolve in water. Hence chalk powder in water is a heterogeneous mixture & is not a true solution.

Substance that is able to get dissolved in solvent is said to be:

  1. solute

  2. insoluble

  3. solvent

  4. soluble
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Soluble substances are those that easily dissolve in a solvent, such as water, and include sugar, salt, alcohol and some dish-washing detergents. In chemistry, solubility of a substance is a quantitative term that refers to the amount of substance that can dissolve in a given volume of a solvent.
