Answers
Answer:
Option (C) Metal + Dilute Nictric Acid
Explanation:
The complete question is:
During which reaction dihydrogen gas is not produced under normal conditions? Select the proper choice from the given multiple choices.
(A) Metal + dilute Sulphuric Acid
(B) Metal + dilute Hydrochloric Acid
(C) Metal + dilute Nitric Acid
(D) Metal + Water
Solution:
Let M be a metal
Lets check the option one-by-one.
Option (A)
Metal + Sulphuric Acid is a displacement reaction where Metal releases Hydrogen gas.
M + H₂SO₄ → MSO₄ + H₂
Option (B)
Metal with dilute HCl also releases the Hydrogen gas just like the above.
Option (C)
When metal reacts with nitric acid the oxides of Nitrogen are formed as Nitric acid is strong oxidising agent. In this case Hydrogen gas is not formed.
Option (D)
When Metal reacts with water,and Metal Hydroxide is formed Hydrogen gas is released.
Therefore, the correct option is option (C)
