Ca + 2 H2O ------> Ca(OH)2 +
H2
If we have 4 moles of Ca and 4 moles of water – how much
Calcium Hydroxide can we make? What would be the limiting reagent
and what would be the one in excess?
Which has the greater octahedral field splitting energy?
(Δo)
[Cr(H2O)6]2+ or [Cr(H2O)6]3+ Blank 1. Fill in the blank, read
surrounding text.
[Fe(NO2)6]3- or [FeCl6]3- Blank 2. Fill in the blank, read
surrounding text.
(Please Note: There was typo that was corrected in the formula.
If you answered using either [Fe(NO2)6]2+ or [Fe(Cl6)6]2+ and were
correct, you will still receive full credit).
Na4[V(CN)4(OH)2] or Na4[Ta(CN)4(OH)2]
: carbonyl(CO) is strong field ligand so [Ni(CO)4] should have
square planar shape but by the experiment [Ni(CO)4] is
tetrahedral.Explain this statement.
For each of the transition metal complex ions
(a) [Ti(NH3)6]2+
(b) [Cr(H2O)4(OH)2]1-
(c) trans–[Pt(CN)2(en)2]2+
(i) Draw the structure of the transition metal complex ion. Show
the charge on the
complex.
(ii) Determine the number of d electrons.
(iii) Draw the ground state arrangement of the d electrons in the
ground state.
(iv) Calculate the LFSE (in units of Δo or ΔT) for each
complex.
Given the following balanced equation Ca3P2 + 6
H2O ----> 3 Ca(OH) + 2 PH3. a) What is the
theoretical yield (in grams) of PH3 produced from 125g
each of Ca3P2 and H2O? b) What is
the limiting reagent? c) What is the percent yield if only 38.9g of
PH3 are produced?
Choose the most likely pattern for the crystal field diagram for
the complex
trans–[Ni(NH3)2(CN)4]2–
where CN– produces a much stronger crystal field than
does NH3.?
From the answer the pattern show it is a square planer. Could
anyone explain it? why is not octahedral?
Consider the four coordinate complexes [FeCl4]2-, [Ni(CN)4]2- or
[AuCl4]-.
a. Which of these complexes do you expect to be square planar?
Why?
b. Explain why this geometry is preferred using a crystal field
splitting diagram and words.
