Concept explainers
(a)
Interpretation:
To determine the formula of diamminetetraaquachromium(II) chloride.
Concept introduction:
Coordination compounds are those in which a transition metal atom is bonded to a ligand which can be neutral, cation or anion. The
A ligand is an atom or a group of atoms or an anion that has an unshared pair of electrons and thus it can act as a Lewis base. It can donate its pair of electrons to the metal atom to form a coordinate bond with the transition metal atom.
(b)
Interpretation:
To determine the formula of tetrachlorosulfatocadmium(III).
Concept introduction:
Coordination compounds are those in which a transition metal atom is bonded to a ligand which can be neutral, cation or anion. The transition metal element is enclosed within a bracket and a charge is present on the ion to balance the charge present on the ligands.

- Quantum mechanics. Explain the basis of approximating the summation to an integral in translational motion.arrow_forwardQuantum mechanics. In translational motion, the summation is replaced by an integral when evaluating the partition function. This is correct becausea) the spacing of the translational energy levels is very small compared to the product kTb) the spacing of the translational energy levels is comparable to the product kTc) the spacing of the translational energy levels is very large compared to the product kTarrow_forwardDon't used Ai solutionarrow_forward
