Question 1

Explain how lines are produced in an emission spectra

Answer 1

Each line results from a transition between definite energy levels. Excited electrons can fall down to lower energy level releasing a photon of light

Question 2

Combined equation E =

Answer 2

E = LHC/ λ

Question 3

Pauli’s Exclusion Principle

Answer 3

If a box contains two electrons one must be pointing up and the other pointing down

Question 4

State the definition of a ligand

Answer 4

Ligands are negative ions or unchanged molecules with one or more non-bonding pairs of electrons

Question 5

An example of a monodentate ligand

Answer 5

Cl-

Question 6

An example of a bidentate ligand

Answer 6

Oxalato

Question 7

What is the definition of a buffer?

Answer 7

A buffer solution is one in which the pH remains approximately constant when small amounts of acid or base or water are added.

Question 8

The formula to calculate ∆S is

Answer 8

∆S = ΣS(products) - ΣS(reactants)

Question 9

The formula to calculate ∆G is

Answer 9

∆G=∆H - T∆S
