The substance not likely to contain CaCO3 is :
Correct answer: A. Calcined gypsum
- A. Calcined gypsum
- B. Sea shells
- C. Dolomite
- D. A marble statue
Explanation
The correct answer is Calcined gypsum. Gypsum is CaSO4 . 2H2O, which does not contain CaCO3. Sea shells contain calcium carbonate (CaCO3). Dolomite is composed of calcium magnesium carbonate, and marble statue consists of CaCO3. Therefore, they are likely to contain CaCO3.

About s-Block and p-Block Elements
The s and p blocks are studied through their valence-shell configurations, periodic trends and characteristic chemical properties. Work covers the reactions of Group I and Group II elements, the behaviour of Group IV elements, and how atomic size, ionization energy, electronegativity and metallic character change across periods and down groups.
