Which of the following will decompose to produce litharge
Correct answer: A. Pb20
- A. Pb20
- B. Pb2O4
- C. PbO2
- D. All of the above
Explanation
Litharge (PbO) is the most common and stable oxide of lead in its lower oxidation state (+2). Pb2O, with its two lead atoms bonded to a single oxygen atom, can decompose relatively easily upon heating, releasing free lead and forming the desired litharge:Pb2O (heat) --> Pb + PbOTherefore, considering the individual properties and decomposition tendencies of the listed lead oxides, Pb2O (option a) stands out as the only one that readily decomposes to produce litharge.

About Transition Elements
Transition elements are identified by their partially filled d subshells in atoms or common ions. The topic covers the electronic structure of d-block elements, including the filling order of 4s and 3d orbitals, variable oxidation states and the distinction between transition elements and elements with completely filled d subshells.
