the chemical formula is different from the empirical formula in
a) co₂.
b) h₂o.
c) h₂o₂.

Explanation:

• For the first question: In atomic orbitals, the s - orbital has a magnetic quantum number \(m_l = 0\). According to the Pauli exclusion principle, each orbital can hold a maximum of 2 electrons (with opposite spins).
• For the second question: The empirical formula gives the simplest whole - number ratio of atoms in a compound. For \(H_2O_2\), the ratio of \(H:O\) is \(1:1\) (simplest ratio), while the chemical formula is \(H_2O_2\). For \(CO_2\), the ratio of \(C:O=1:2\) (already the simplest ratio, so empirical formula is same as chemical formula). For \(H_2O\), the ratio of \(H:O = 2:1\) (already the simplest ratio, so empirical formula is same as chemical formula).

Answer:

• First question: C. two electrons.
• Second question: C. \(H_2O_2\).
