Multiple choice chemistry separation of substances substances and mixtures formation of mixtures and types of mixtures based on states types of mixtures

The constituents of the mixture are easily seen with naked eyes. Then the mixture is ____________.

  1. Homogenous

  2. Heterogenous

  3. Both (a) and (b)

  4. None of these
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The homogenous mixture consists of different components which are uniformly distributed in the solution and it can't be seen with naked eyes.

The heterogeneous mixture consists of two or more parts which have different compositions. These have visible boundaries of separation between the different constituents and can be easily seen even with naked eyes.

The example of heterogeneous mixture is:

  1. Water and stone.

  2. Water and lemon juice.

  3. Water and alcohol.

  4. Water and sugar.
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

A heterogeneous mixture is simply any mixture that is not uniform in composition. Two immiscible liquids form heterogeneous mixtures.

In given examples, water & lemon juice, water & alcohol, water & sugar result in uniform composition forming homogeneous mixture.
$\therefore$ Water and stone is a heterogeneous mixture.

A mixture refers to the physical combination of two or more substances on which the chemical identities are retained and are mixed in the form of solutions, suspensions, and colloids.

  1. True

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

A mixture is indeed a physical combination of two or more substances where each retains its own chemical identity. They can exist as solutions, suspensions, or colloids.

Vinegar is a solution of acetic acid in water, it is:

  1. a homogeneous solid in liquid mixture

  2. a heterogeneous liquid in liquid mixture

  3. a homogeneous liquid in liquid mixture

  4. none of these
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
Vinegar is homogenous solution because it is a completely uniform solution of liquid in liquid type of mixture (acetic acid in water)
Multiple choice chemistry separation of substances substances and mixtures formation of mixtures and types of mixtures based on states types of mixtures

Unlike gases, can all liquids in liquid mixtures form solutions.

  1. True

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

No, not all liquids in liquids mixture form solutions

we know that "like dissolve like", so, the liquids which have same polarity only form solutions.
for example: water and oil have different polarity and hence they do not form solution.

Which pair is a miscible liquid mixture?

  1. Ethylalcohol and water

  2. Mercury and alcohol

  3. Benzene and water

  4. Carbondisulphide and water
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
Water is polar and has hydrogen bonding. Since, ethyl alcohol has oxygen atom it also undergoes hydrogen bonding when mixed with water. Also, ethyl alcohol is polar due to high electro-negativity of $O$, due to which it mixes with water. Hence, ethyl alcohol and water are a pair of miscible liquid mixture. 
Multiple choice chemistry non-metals dihydrogen fuel dihydrogen as a fuel introduction to hydrogen

In which of the following way, the transportation of hydrogen gas do not take place?

  1. Liquid

  2. Gas

  3. Compressed gas

  4. Pressurized gas
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The transportation of hydrogen gas is done in heavy metal cylinders and it can also be transported in liquid form. In order to transport large amounts of hydrogen it must be either pressurized and delivered as a compressed gas, or liquefied.

  1. Solids

  2. Liquid

  3. Gas

  4. Both B and c
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Lubricants can be solid, liquid, or gas, but liquids are the most common and generally considered the most effective for reducing friction in machinery.

Multiple choice surface tension physics surface energy of a liquid work done in stretching a liquid surface: surface energy of a liquid properties of matter

Two drops of a liquid are merged to from a single drop. In this process-

  1. Energy is released

  2. Energy is absorbed

  3. Energy remains constant

  4. First B then A
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

It is nature of free surface to always minimize the surface tension; Hence when two bubble fuse then energy is released due to decrease in surface Tension.

Multiple choice surface tension physics surface energy of a liquid work done in stretching a liquid surface: surface energy of a liquid properties of matter

Potential energy of a molecule on the surface of a liquid is as compared to another molecule inside of the liquid is

  1. More

  2. Less

  3. Both a and b

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

Due to surface Tension, Potential energy of a molecule at free surface is more than the molecules inside the liquid.
