Question

An ore of zinc when reacts with dilute hydrochloric acid produce a gas with smell of rotten egg. Name the ore. write the steps involve during the extraction of metal (Zn) from it's ore​

Answer 1

Answer: Zn + HCl —> ZnCl2 + H2

Explanation: when zinc reacts with hydrochloric acid it gives zinc chloride and hydrogen gas . This can be tested by bringing the test tube close to a flame and a pop sound will be heard .

Extraction of zinc from its ore:

Reduction of oxide ore : process of conversion of metal oxide ore into metal . It can be done by heating the oxides with suitable reducing agents like carbon in the form of coke .

ZnO+ C (coke) —> Zn + CO

Sometimes displacement reactions also reduce metal oxides to metals

Answer 2

Answer: it’s zinc blende

Explanation:

It’s zinc blende because

Zinc blende is a sulphide Ore, so the sulphur gas produced due to the reaction with sulphide ore gives a smell of rotten egg
