Write a formulae equation to represent the combustion of carbon to form carbon dioxide and the thermal decomposition of magnesium carbonate

Explanation:

Balanced equation to represent the combustion of carbon to form carbon dioxide;

C (s) + O₂ (g) → CO₂ (g)

Balanced equation to represent the thermal decomposition of magnesium carbonate

MgCO₃ (s) → MgO (s) + CO₂ (g)

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.
