Consider the complex ion [CO(NH3)6]3+. Which response contains all of the following statements that are true, and no false statements?

I. It is paramagnetic.
II. It is a high spin complex.
III. It is a low spin complex.
IV. It has octahedral geometry.
V. It does not exist as geometric isomers.

a. III, IV, and V
b. II, IV, and V
c. land II
d. land IV
e. III and IV

III, IV, and V

Explanation:

The complex [CO(NH3)6]3+ is a diamagnetic complex. It a low spin d^6 complex. Most d^6 complexes are low spin due to the higher crystal field stabilization energy of the low spin over the high spin arrangement.

d^6 metal complexes are known to be octahedral (a coordination number of 6 leads to octahedral geometry). Octahedral complexes does not have geometric isomers rather, may exist as the fac or her stereo isomers.

the electron configuration that you gave me has 16 electrons ergo it has 16 protons ergo it is the element sulfur.

a gas, having a molecular weight of 13 kg/kmol and a kinematic viscosity of 0.25 cm2/s, flows through a pipe 0.25 m internal diameter and 5 km long at the rate of 0.4 m3/s and is delivered at atmospheric pressure.
