Hydrochloric acid reacts with a metal 'A' to form a gas 'B' which burns with a 'pop' sound. Sodium hydroxide solution also reacts with the same metal A on heating to form the same gas B
Name A & B
Write chemical reaction of metal A with -
(a) Hydrochloric acid

(b) Sodium hydroxide soln

Q. Hydrochloric acid reacts with a metal X to form a gas Y which burns with a 'pop' sound. Sodium hydroxide solution also reacts with the same metal X (on heating) to form the same gas Y.
(a) Name X and Y
(b) Write the chemical equation of the reaction of metal X with (i) hydrochloric acid, and (ii) sodium hydroxide solution.

Q.

The metal X reacts with dilute hydrochloric acid to form a gas Y.The metal X also reacts with sodium hydroxide solution (on heating) to form the same gas Y.When a lighted matchstick is applied,this gas burns by producing a 'pop' sound.

(a) Name two metals which could behave like X.

(b) Name the gas Y.

Q. Which of the given metals produces hydrogen gas on reacting with hydrochloric acid as well as sodium hydroxide solution?​

Q.

Name the gas produced when aluminium foil reacts with :

(a) dilute hydrochloric acid.

(b) sodium hydroxide solution.

Q. An organic compound C(molecular formula C2 H4 O2) reacts with sodium metal to form a compound B and evolves a gas which burns with a pop sound.Compound C on treatment with an alcohol A in presence of an acid forms a sweet smelling compound S(molecular formula C4 H8 O2).On addition of sodium hydroxide to C it also gives B and water.S on treatment with Sodium Hydroxide solution gives back B and A.
Identify A,B,C and and write chemical equation for all the four reactions involved.
