calcium oxide (quicklime) and carbon dioxide
it is the decomposition reaction, CaCO3 = CaO + CO2
The surface of limestone crumbles when heated because heat causes the moisture and other volatiles in the limestone to evaporate rapidly, leading to a process known as thermal spalling. This rapid evaporation creates pressure within the limestone, leading to the breakdown of its structure and causing it to crumble.
its heated with something
Acid rain, which is formed from the reaction of carbon dioxide and water in the atmosphere, can dissolve the calcium carbonate in limestone statues through a chemical process known as carbonation. This leads to the breakdown and erosion of the limestone over time.
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.
quicklime is formed when lmesone is heated
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.
No. Limestone changes to Marble when it undergoes intense heat and pressure.
When limestone (CaCO3) is heated, calcium oxide is produced!
Heating of limestone is a decomposition reaction as limestone decomposes to give calcium oxide and carbon dioxide.
Limestone and sand stone are both sedimentary rocks, and marble is made out of limestone when heated . :) Hope that helped.
