What substance is made when limestone and clay are heated together?
Limestone, CaCO3 decomposes into quicklime, CaO, and carbon dioxide, CO2, when heated. The reaction is: CaCO3 + heat --> CaO + CO2.
What substances are created when calcium carbonate is heated very strongly in an open crucible?
Calcium carbonate thermally decomposes when heated to form calcium oxide powder and carbon dioxide gas. The word equation: calcium carbonate --> calcium oxide + carbon dioxide As a symbol equation: CaCO3 --> CaO + CO2
What happens when Hg oxide is heated?
When mercuric oxide is strongly heated in a hard glass tube, it decomposes, globules of mercury collect in the cooler part of the tube and oxygen gas is evolved. It may be collected over mercury in a pure and dry state.
