Question

Metals which are extracted by heating, electrolysis and by reduction with carbon respectively are a. Copper, magnc::sium, zinc b. Mercury, aluminium, lead c. Mercury, sodium, calcium d. Both a and b

Answer 1

Mercury sodium and calcium

A's sodium is highly reactive it even reacts at room temperature

Answer 2

Option D is the correct answer to the question. Thus, copper, magnesium, zinc, mercury, aluminum, and lead are the metals that are extracted by heating, electrolysis, and by reduction with carbon respectively.

• The approach used to extract metals from the ore wherein they're observed relies upon their reactivity.
• For example, reactive metals inclusive of aluminum are extracted with the aid of using electrolysis, at the same time as a much less-reactive steel inclusive of iron can be extracted with the aid of using discount with carbon or carbon monoxide.
• The metals low withinside the reactive collection are very much less reactive.
• The oxides of such metals may be decreased to metals with the aid of using heating by myself e.g. mercury is received from its ore, cinnabar (HgS), with the aid of using the manner of heating.
• Metals like iron, zinc, lead, etc. arise as sulfides or carbonates in nature.
• First the ore is transformed into its oxide shape. This is performed with the aid of using both roastings or with the aid of using calcination.
• The steel oxide is decreased to steel with the aid of using the usage of appropriate lowering agent inclusive of Carbon.
