Assertion & Reason Test: Metals & Non-metals - Question 1
Save

Directions: In the following questions, a statement of assertion (A) is followed by a statement of reason (R).
Mark the correct choice as:

Assertion (A): When a piece of copper metal is added to dilute sulphuric acid, the solution turns blue.

Reason (R): Copper reacts with dilute sulphuric acid to form blue copper (II) sulphate solution.

Detailed Solution for Assertion & Reason Test: Metals & Non-metals - Question 1

When a piece of copper metal is added to dilute sulphuric acid, then it shows no reaction at normal temperature. It is because, copper reacts only with heated sulphuric ac to form blue copper (W) sulphate solution and reason is  
false as copper cannot displace hydrogen , as it is less reactive than it

Directions: In the following questions, a statement of assertion (A) is followed by a statement of reason (R).
Mark the correct choice as:
Assertion (A): Metals are sonorous.
Reason (R): They are generally brittle in the solid state; they break into pieces when hammered.

Detailed Solution for Assertion & Reason Test: Metals & Non-metals - Question 2

Metals are sonorous, malleable and ductile while non-metals are brittle.

Directions: In the following questions, a statement of assertion (A) is followed by a statement of reason (R).
Mark the correct choice as:
Assertion (A): Gas bubbles are observed when sodium carbonate is added to dilute hydrochloric acid.
Reason (R): Carbon dioxide is given off in the reaction.

Detailed Solution for Assertion & Reason Test: Metals & Non-metals - Question 3

Gas bubbles are observed when sodium carbonate is added to dilute hydrochloric acid as CO2 gas is released.

Assertion & Reason Test: Metals & Non-metals - Question 4

Directions: In the following questions, a statement of assertion (A) is followed by a statement of reason (R).
Mark the correct choice as:

Assertion (A): In alumino thermite process, the metals like iron melts due to the heat evolved in the reaction.

Reason (R): The reaction is:

Fe2O3 + 2Al → Al2O3 + 2Fe
Detailed Solution for Assertion & Reason Test: Metals & Non-metals - Question 4

Large amount of heat is evolved which melts iron and can be used for welding.

Assertion & Reason Test: Metals & Non-metals - Question 5
Save

Directions: In the following questions, a statement of assertion (A) is followed by a statement of reason (R).
Mark the correct choice as:

Assertion (A): Usually the sulphide ore is converted to oxide before reduction.

Reason (R): Reduction of oxides occurs easier.
Detailed Solution for Assertion & Reason Test: Metals & Non-metals - Question 5

Usually the sulphide ore is converted to oxide before reduction as oxides are easier to reduce.

Assertion & Reason Test: Metals & Non-metals - Question 6
Save

Directions: In the following questions, a statement of assertion (A) is followed by a statement of reason (R).
Mark the correct choice as:
Assertion (A): A mineral is called ore, when metal is extracted from it conveniently and economically.

Reason (R): All ores are minerals but all minerals are not ores.
Detailed Solution for Assertion & Reason Test: Metals & Non-metals - Question 6

Minerals are naturally occurring chemical substances in the earth’s crust obtained by mining. But a mineral is called an ore only when the metal can be extracted from it conveniently and economically. Thus, all ores are minerals but all minerals are not ores.

Assertion & Reason Test: Metals & Non-metals - Question 7
Save

Directions: In the following questions, a statement of assertion (A) is followed by a statement of reason (R).
Mark the correct choice as:
Assertion (A): While the extraction of copper, one of the steps involved is

Cu2S + 2Cu2 O → 6Cu + SO2

Reason (R): In this reaction Cu2S is the reducing agent whereas Cu2O is the oxidising agent.
Detailed Solution for Assertion & Reason Test: Metals & Non-metals - Question 7

The reaction shown is a redox reaction where Cu₂S (copper(I) sulfide) is being oxidized to copper metal (Cu), and Cu₂O (copper(I) oxide) is being reduced to copper metal (Cu).

  • Cu₂S is the reducing agent because it loses sulfur and gains oxygen in the form of Cu₂O.
  • Cu₂O is the oxidizing agent because it accepts electrons from Cu₂S and gets reduced to copper metal.
Assertion & Reason Test: Metals & Non-metals - Question 8
Save

Directions: In the following questions, a statement of assertion (A) is followed by a statement of reason (R).
Mark the correct choice as:
Assertion (A): In the metallurgy of Al, purified Al2O3 is mixed with Na3AlF6 or CaF2.

Reason (R): It lowers the melting point of the mixture and brings conductivity.
Detailed Solution for Assertion & Reason Test: Metals & Non-metals - Question 8

In the metallurgy of aluminium, purified Al2O3 is mixed with Na3AlF6 or CaF2 which lowers the melting point of the mixture and brings conductivity.

Assertion & Reason Test: Metals & Non-metals - Question 9
Save

Directions: In the following questions, a statement of assertion (A) is followed by a statement of reason (R).
Mark the correct choice as:

Assertion: Different metals have different reactivities with water and dilute acids.

Reason: Reactivity of a metal depends on its position in the reactivity series.
Detailed Solution for Assertion & Reason Test: Metals & Non-metals - Question 9

Both assertion (A) and reason (R) are true and reason (R) is the correct explanation of assertion (A). The metals placed at the top of the series are most reactive.
