Magnesite (Magnesium carbonate) is calcined to obtain magnesia, which is used to make refractory bricks. Write the decomposition reaction.

Text Solution

Verified by Experts

Magnesite is a carbonate of magnesium . Magnesite when heated at `800^@C` to `100^@C` at the `CO_2` content in it driven off. The residue so obtained is known as calcined magnesite.
