The number of ligands which are directly bonded to the metal is known as

Which of the following sets of ligands does $NOT$ contain an ambident ligand?

What is the number of moles of donor atoms present in one mole of oxalate ion?

Generally,a group of atoms can function as a ligand if:

An excess of $AgNO_3$ is added to $100 \ mL$ of a $0.05 \ M$ solution of tetraaquadichloridochromium$(III)$ chloride. The number of moles of $AgCl$ precipitated will be . . . . . . $\times 10^{-3}$. (Nearest integer)

Consider the following complex $[Co(NH_3)_5CO_3]ClO_4$. The coordination number,oxidation number,number of $d-$ electrons,and number of unpaired $d-$ electrons on the metal are respectively:
