I believe the answer would be c?? I’m not too sure though
As thermal energy increases and there is more particle movement.
- Thermal energy is the energy possessed by the system or object due to the movement of its particles.
- For example kinetic energy of the particles
- Higher the motion of the particles more will be the thermal energy of the system or object and vice-versa
- It is also termed as heat energy of a system or object
- The higher the thermal energy, the higher will be the temperature and vice versa.
So, from this, we can conclude that as thermal energy increases and there is more particle movement.

This problem is requiring the empirical formula for CaCO₃, which is its molecular formula, and turns out to be equal, this is A. CaCO3 according to the following:
<h3>Empirical formulas:</h3><h3 />
In chemistry, molecular formulas show both the actual type and number of atoms in a chemical compound, based on the elements across the periodic table and the subscripts standing for the number of atoms in the compound.
However, the empirical formula is a reduced expression of the molecular one, which shows the minimum number of atoms in a compound after simplifying to the smallest whole numbers.
In such a way, since the given compound is CaCO₃ and both Ca and C have a one as their subscript, it is not possible to simplify any further and therefore the empirical formula equals the molecular one this time, making the answer to be A. CaCO3.
