carbon dioxide
calcium oxide (quicklime)
CaCO3 > CaO + CO2
When limestone is heated under pressure, it forms marble. This process, known as metamorphism, occurs when the mineral calcite in the limestone recrystallizes into the interlocking calcite crystals that compose marble.
it is the decomposition reaction, CaCO3 = CaO + CO2
Glass is made from a mixture of sand, soda ash, and limestone that is heated until it melts. The molten mixture is then poured into molds or shaped by blowing to create various glass products.
When lead nitrate is heated strongly, it decomposes to form lead oxide, nitrogen dioxide gas, and oxygen gas.
When lead nitrate is strongly heated, it decomposes to produce nitrogen dioxide gas (NO2), which is a brown gas with a sharp, acrid odor.
quicklime is formed when lmesone is heated
Carbon Dioxide (CO2)
The balanced chemical equation for limestone (calcium carbonate, CaCO3) being heated strongly in air is: CaCO3(s) → CaO(s) + CO2(g)
This is a thermal decoposition: CaCO3 --------CaO + CO2
CaCO3 -----> CaO + CO2 - Calcium carbonate has a MWt of 100 so 50 g is half a mole so 0.5 moles of CaO MWt 56 and so 28g produced and Carbon Dioxide is MWt 44 so 22g produced.
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 calcium carbonate (limestone, CaCO3) breaks down, carbon dioxide (CO2, gas) and calcium oxide (CO, solid) are formed
when natural gas is strongly heated, hydrogen(H) and carbon(C) are obtained.
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.
