The balanced chemical equation for limestone (calcium carbonate, CaCO3) being heated strongly in air is: CaCO3(s) → CaO(s) + CO2(g)
simply it breaks out due to forming of carbon dioxide in the gaps if it takes place in an close atmosphere with high pressure than turns into marble.
Limestone is the rock that is squeezed and heated to form marble. The high pressures and temperatures cause the limestone to recrystallize and become the metamorphic rock known as marble.
Heating limestone causes it to undergo thermal decomposition, releasing carbon dioxide gas. This process forms calcium oxide, also known as quicklime, as a residue.
i will ask a friend
Carbon Dioxide (CO2)
The balanced chemical equation for limestone (calcium carbonate, CaCO3) being heated strongly in air is: CaCO3(s) → CaO(s) + CO2(g)
carbon dioxide calcium oxide (quicklime) CaCO3 > CaO + CO2
This is a thermal decoposition: CaCO3 --------CaO + CO2
its heated with something
calcium carbonate (limestone)
When heated, limestone forms two different things. It forms both calcium oxide and carbon dioxide. This occurs because limestone is made up of calcium carbonate.
simply it breaks out due to forming of carbon dioxide in the gaps if it takes place in an close atmosphere with high pressure than turns into marble.
when natural gas is strongly heated, hydrogen(H) and carbon(C) are obtained.
quicklime is formed when lmesone is heated
