Question

explain with a suitable example the metal usd yo reduce the following a)oxides of less reactive metals

Answer 1

The less reactive metals which are quite low in metal reactivity series are extracted by the reduction of their oxides by heat alone.
    Example - Extraction of mercury from Cinnabar

Answer 2

Oxides of less reactive metals are reduced simply by heating those oxides.

Explanation:

• Usually metals are reduced to obtain the pure metal from its oxide compound.

• The metals like mercury, platinum, gold have less reactivity to oxygen and hence it just need to be heated to reduce its oxide to obtain the pure metal.

• Example  $Hg + O \rightarrow Hg + O_2$ (in presence of heat).

• The metals like Lead, Zinc, Iron, Copper are moderate reactive metals.

• These metals when exposed to oxygen form those respective metals oxides.

• These metals oxides are reduced by heating them with the carbon atom.

• Example $ZnO + C\rightarrow Zn + CO$ (in presence of heat).
