Answer 1

Answer: (A), (C), (D)

The correct options are
A

Gold is the most malleable metal while platinum is the most ductile one.

C

Gold, silver, platinum are used to make ornaments.

D

Zinc reacts with dilute hydrochloric acid to produce zinc chloride and water

Gold is the most malleable metal while platinum is the most ductile one.

Gold, silver, and platinum are used to make ornaments as they maintain their metallic lustre for a long time because they do not react with oxygen and moisture present in the atmosphere.

Zinc reacts with dilute hydrochloric acid to produce zinc chloride and hydrogen gas.
