Which consequence results when a large deposit of calcium carbonate is heated strongly?

A)Increased oxide availability for slagging
B)Molecular lattice rigidity improvement occurs
C)Hydrogen bonding becomes proportionally stronger
D)Stabilization against thermal chain scission

💡 Explanation

Heating decomposes CaCO3 via thermal decomposition to CaO and CO2. The *thermal decomposition* process yields more calcium oxide, therefore its reactivity increases for impurity removal in metallurgy, rather than strengthening lattices or affecting H-bonding.
