0.02 g of calcium carbonate (CaCO₃)
Explanation:
To solve the question we use the Avogadro's number using the following reasoning:
if 1 moles of calcium carbonate contains 6.022 × 10²³ units of calcium carbonate
then X moles of calcium carbonate contains 12.044 × 10²³ units of calcium carbonate
X = (1 × 12.044 × 10²³) / 6.022 × 10²³ = 2 moles of calcium carbonate
mass = number of moles × molecular weight
mass of calcium carbonate (CaCO₃) = 2 / 100 = 0.02 g

Answer: Electrons in bonding orbitals stabilize the molecule because they are between the nuclei. They also have lower energies because they are closer to the nuclei. Antibonding orbitals place less electron density between the nuclei. The nuclear repulsions are greater, so the energy of the molecule increases.
