What is the chemical equation for limestone being heated strongly in air?

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


50g of limestone were heated strongly so that all of the limestone turned into the products?

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.

when natural gas is strongly heated, hydrogen(H) and carbon(C) are obtained.


What rock is squeezed and heated to form 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.
