⇝ Question :-

Identify X,Y, Z and M and write the corresponding chemical equations.

when,

• A metal M reacts with a substance X to produce a gas Y that burns with a pop sound.

• X also reacts with a metal carbonate to produce a gas Z that turns lime water milky.

• When X reacts with the base Ca(OH)2 it forms the corresponding sulphate salt M.

⇝ Chemical Equations :-

⇝ Explanation :-

• We know that Hydrogen gives pop up sound on burning therefore the gas Y should be Hydrogen (H₂.)

• We know that carbon dioxide turns Lime water milky therefore the gas Z should be Carbon dioxide (CO₂).

• We Know that when Metals react with acids produces Hydrogen therefore substance X should be an Acid.

• Given that when X reacts with Ca(OH)₂ it forms corresponding sulphate therefore the acid should be Sulfuric acid (H₂SO₄).

• As Given When H₂SO₄ reacts with Ca(OH)₂ it forms Metal Sulphate and in reactants the only metal is calcium (Ca) so in product the metal M will be calcium (Ca).
