Mixture perfectly uniform in its composition and properties throughout its bulk is called :

chemistry pure substances and mixtures: separation of mixtures mixtures: examples and properties types of solutions all about mixtures

  1. homogeneous mixture

  2. heterogeneous mixture

  3. both A and B

  4. none of the above

Show answer
Correct Option: A
Explanation:

Mixture perfectly uniform in its composition and properties throughout its bulk is called homogeneous mixture, e.g., solution of alcohol in water, dust free air etc.

Sulphuric acid is added to water. What will you get ?

chemistry pure substances and mixtures: separation of mixtures mixtures: examples and properties types of solutions all about mixtures

  1. Element

  2. Mixture

  3. Compound

  4. None of these

Show answer
Correct Option: B
Explanation:

We will get a homogeneous mixture which will be an aqueous solution of sulphuric acid and water making the acid dilute as no reaction takes place between sulphuric acid and water.

Among the following, bronze is a/an example of :

chemistry pure substances and mixtures: separation of mixtures mixtures: examples and properties types of solutions all about mixtures

  1. an element

  2. a mixture

  3. a compounds

  4. all of these

Show answer
Correct Option: B
Explanation:

Bronze is a alloy, it is composed of the mixture of copper and tin. It was made before 3000 bc, though its use in artifacts did not become common until much later. The proportions of copper and tin varied widely (from 67 to 95 percent copper in surviving artifacts).

Sulphur powder and iron filings is an example of :

chemistry pure substances and mixtures: separation of mixtures mixtures: examples and properties types of solutions all about mixtures

  1. homogenous mixture

  2. heterogeneous mixture

  3. compounds

  4. All of the above

Show answer
Correct Option: B
Explanation:

Mixture with different compositions and different properties at different locations in the mixture is called heterogeneous mixture.

Mixture with different compositions and different properties at different locations in the mixture is called a :

chemistry pure substances and mixtures: separation of mixtures mixtures: examples and properties types of solutions all about mixtures

  1. homogeneous mixture

  2. heterogeneous mixture

  3. Both A and B

  4. None of the above

Show answer
Correct Option: B
Explanation:

Heterogeneous mixture is a mixture that consists of physically different parts each with different properties.

Tap water is:

chemistry composition of matter classification of mixtures mixtures: examples and properties types of solutions

  1. compound

  2. a mixture

  3. an element

  4. none of these

Show answer
Correct Option: B
Explanation:

Tap water is not the pure form of water, it contains a large number of salts, elements, bacteria and other impurities,

so, tap water is considered as a mixture.

Identify the mixture from the following:

chemistry separation of substances classification of mixtures mixtures: examples and properties types of solutions

  1. Oxygen

  2. Carbon dioxide

  3. Hydrogen

  4. Air

Show answer
Correct Option: D
Explanation:

The mixture consists of constituents in indefinite proportion. It may change over time. Air has 78% Nitrogen, 21% Oxygen and 1% other constituents such as $CO _2$, water vapour etc. About 100 years ago the proportion of $CO _2$ in the air was about 0.029% and now it is 0.035%. Thus we see that it's proportion has changed.

Which of the following is a mixture?

chemistry separation of substances classification of mixtures mixtures: examples and properties types of solutions

  1. Water

  2. Oxygen

  3. Carbon dioxide

  4. Air

Show answer
Correct Option: D
Explanation:

A mixture consists of constituents in indefinite proportion. It may change over time. Air has 78% Nitrogen, 21% Oxygen and 1% other constituents such as CO2, water vapour etc. About 100 years ago proportion of CO2 in air was about 0.029% and now it is 0.035%. Thus we see that it's proportion has changed. Therefore, air is a mixture.

A substance that cannot be separated into other kinds of matter by any physical process is known as :

chemistry separation of substances classification of mixtures mixtures: examples and properties types of solutions

  1. element

  2. compound

  3. solution

  4. mixture

Show answer
Correct Option: A
Explanation:

Elements are the fundamental particles of all kinds of matter. They can't be separated by any physical or chemical means.
