In the manufacture of steel by open hearth process, the slag obtained is:
Correct answer: D. All
- A. CaSiO3
- B. FeSiO3
- C. MnSiO3
- D. All
Explanation
This option of all is correct because during the steelmaking process, various oxides such as CaO, FeO, MnO, SiO2, and others are present in the slag. The exact composition can vary depending on the specific conditions of the process and the composition of the raw materials used.

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.
