Question

Heating limestone at a temperature of 1070 K we get________.

Answer 1

Heating limestone at a temperature of $1070\mathrm{K}$

• When limestone (${\mathrm{CaCO}}_3$) is heated at a temperature of $1070\mathrm{K}$ we get quick lime($\mathrm{CaO}$).
• Reaction showing the formation of quicklime
  $\underset{\mathrm{Calcium}\mathrm{carbonate}}{{\mathrm{CaCO}}_3\left(\mathrm{s}\right)}\stackrel{1070\mathrm{K}}{\to }\underset{\mathrm{Calcium}\mathrm{oxide}}{\mathrm{CaO}\left(\mathrm{s}\right)}+\underset{\mathrm{Carbon}\mathrm{dioxide}}{{\mathrm{CO}}_2\left(\mathrm{g}\right)}$
• Calcium oxide can be produced by the thermal decomposition of materials like limestone or seashells that contain Calcium carbonate.

Hence, by heating limestone at a temperature of $1070\mathrm{K}$ we get quicklime.
