Metals react with acids to produce _____________ gas.

(a) Name one metal which reacts with dilute hydrochloric acid to produce hydrogen gas.

(b)Name one metal which does not react with dilute hydrochloric acid.

Name a gas which is always produced when a reactive metal reacts with a dilute acid. Write a chemical equation supporting your answer.

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.

Name the gas evolved when a metal reacts with a dilute acid.

it is said that metals react with acids to produce hydrogen gas. then how can hydrogen gas be produced when a metal reacts with sodium hydroxide(base)??
