Question

Mark ‘True’ if the statement is true and ‘False’ if it is false.​
(a) Generally, non-metals react with acids.​(b) Sodium is a very reactive metal.
(c) Copper displaces zinc from zinc sulphate solution.
(d) Coal can be drawn into wires.

Answer 1

(a)Correct answer - False

Non-metals do not react with acids, but metals do react with acids to produce hydrogen gas.​

(b) Correct answer - True​

Sodium is a very reactive metal as it vigorously reacts with water and oxygen, so it is stored in kerosene. ​

(c) Correct answer - False​

• Copper is less reactive as compared to zinc. ​

• Thus, copper cannot displace zinc from zinc sulphate solution.​

(d)Correct answer - False​

Coal is made up of carbon which is a non-metal. ​

So, coal cannot be drawn into wires. Hence, non-ductile.​
