Question

write the chemical equation for the following metals which are obtained from their compounds by reduction process . metal which is low in reactivity series

Answer 1

➶➶➶➶➶[ ANSWER ]➷➷➷➷➷


The metals that lies in the bottom of the reactivity series are reduced by heating.

EXAMPLE:-


2HgO------->2 Hg +O2.

Answer 2

Metal X is obtained simply by heating their oxides with carbon. e.g., mercury is obtained from cinnabar.

(ii) Metals in the middle of activity series can be obtained by heating with carbon, e.g.,

(iii) Metal high in the reactivity series are obtained by electrolytic reduction of molten ores e.g., in NaCl
