Answer:
ask only one question not this much
question :What is the difference between a mineral and an ore ?
-Minerals are naturally occurring inorganic solids with a crystalline structure and a definite range of chemical formula. Ores are concentrations of minerals in rock that are high enough to be economically extracted for use. ... All rocks are made of minerals.
question : Which metal is extracted from cinnabar ore ?
- Mercury
Extraction of Mercury. Most of the world's mercury is obtained from its main ore, cinnabar or vermillion with the chemical structure mercury sulphide (HgS).
question : Name one ore of sodium. Name the sodium compound present in this ore and write its chemical formula.
-The ore of sodium is rock salt. The sodium compound present in this ore is sodium chloride. The chemical formula of the ore is NaCl
question : How is sodium metal extracted ? Explain with the help of equation of the reaction involved.
-Sodium is extracted by electrolytic reduction of molten sodium chloride. On passing electricity through molten sodium chloride, decomposition occurs and sodium metal and chlorine gas are formed. ... These chloride ions are oxidised to chlorine gas. Chlorine gas is produced at the anode.
question :Name three other metals which are extracted in a manner similar to sodium.
-Potassium, calcium and aluminium are highly reactive metals like sodium and are also placed on the top of the reactivity series.
