Limestone is obtained by mining.
when limestone is heated with clay it forms cement.
If limestone is heated in air calcium oxide (lime) forms. If limestone is heated under pressure of rock layers, marble forms.
Marble is a metamorphic(characterized by change of form) limestone. When the limestone is heated and pressure is put on it, the calcite(CaCO3) in it melts. If the limestone was pure before heat or pressure was applied to it, a white marble will be obtained. If it had hematite or haematite(iron oxide, Fe2O3) or clay in it, reddish marble will be obtained.
when limestone is heated strongly the product you get out of it is quick lime
its heated with something
when limestone is heated a gas is produced which is carbon dioxide and solid calcium oxide is produced.
It is obtained from cinnabar. Cinnabar is first heated and the product obtained is heated again which is mixed with cinnabar again. Hence mercury is obtained as a product.
quicklime is formed when lmesone is heated
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.
Limestone, CaCO3 decomposes into quicklime, CaO, and carbon dioxide, CO2, when heated. The reaction is: CaCO3 + heat --> CaO + CO2.
Most substances expand when heated.
By digging with a spoon.
when natural gas is strongly heated, hydrogen(H) and carbon(C) are obtained.
No. Limestone changes to Marble when it undergoes intense heat and pressure.
When limestone (CaCO3) is heated, calcium oxide is produced!
Heat will not change limestone to sandstone. Heat and pressure could change limestone to marble however.
Heating of limestone is a decomposition reaction as limestone decomposes to give calcium oxide and carbon dioxide.
when substance heated,their intermolecular bonding is break at required temperature,there for molecules are free to move;thus substances are expand when heated.
because in a blast furnace the limestone removes unwanted substances as slag.
it's shaken not stirred
