Homework Answers
1.) The correct option is option D. ie the conjugate acid is H2PO4-.
2.) In V2O5 the oxidation state of V is +5 it means V has lost 3 electrons from d shell and 2 electrons from s shell having no or zero electrons in d orbital. The correct option js option D.
3.) The correct option is option D. Option D represents the correct electronic configuration for transition elements.
