Question

An element x on reaction with dilute hcl acid evolves a gas that burns with a pop sound while a compound y on reaction with dilute acid evolves a gas that turns lime water milky

Answer 1

The element x on reacting with HCl gives a gas that burns with a pop sound.

So, we know that hydrogen is a gas that burn with a pop sound.

A compound y on reaction with dilute acid evolves a gas that turns lime water milky.

So the gas which is evolved is carbon dioxide because that gas turns lime water milky.

See brother, there is no trace or evidence given about the elements so the name of those elements cant be determined. But yes the element x is a metal because metal reacts with acid and give out hydrogen and a salt.

And the element y is a compound of a metal which gives metal salt, carbon dioxide and water.

The element x could be Na.

The element y could be Na2CO3.

Hope my answer helped you if yes then please mark it as brainliest.

Answer 2

X is metal and Y is metalcarbonate.
