Answer:
No. of electrons of the element
Limestone (CaCO₃) is the second most abundant mineral on Earth after SiO₂. For many uses, it is first decomposed thermally to quicklime (CaO). MgO is prepared similarly from MgCO₃.
AT 871°C CaCO 3 needs about 1 hour for complete decomposition.
<h3>
At what temperature Caco3 decompose to Cao?</h3>
At any temperature higher than 835°C, the value of Δ G ∘ will be negative and the decomposition reaction will be spontaneous.
AT 871°C CaCO 3 needs about 1 hour for complete decomposition.
Calcium carbonate decomposes on heating to give calcium oxide and carbon dioxide.
