Question
The charge on the complex ion in the compound Mg_2 [FeCl_6] is ___________. The oxidation number of chromium in [Cr(NH_3)_4Cl_2]Cl is___________. The correct name for [Ni(NH_3)_6](NO_3)_3 is ____________. Triphenylphosphine is often given the abbreviated formula PPh_3. The correct name for [Rh(PPh_3) (Valance Bond Theory) Magnetic measurements indicate that [Co(OH_2)_6]^2+ has 3 unpaired electron Therefore. the hybridization of the metal's orbitals in [Co(OH_2)_6]^2+ is ____________ In metallic hydrides, the oxidation number of hydrogen is considered to be ______________. How many ligands are there in the coordination sphere of [Co(en)_2Cl_2]? ______________. The correct formula for potassium diaquatetrachloromolybdate (III) is ____________. The total number of d electron(s) associated with the metal ion in [Cr(NH_3)_6]^3+ is/are ________ The oxidation state of silicon in SiO_4^4- is _________. An example of a molecular hydride is __________Explanation / Answer
Answer 1. The iron must be +2 charge in compound Mg[FeCl6].
Answer 2: The counter ion in [Cr(NH3)4Cl2] is Cl while Cl is -1 therefore the overall charge of the complex is +1.
Using the formula:
metal oxidation state = overall complex charge - ligand charge
Oxidation state of Cr = +1 - (4 x NH3 + 2xCl) = +1 - (-2) = +3.
Answer 3: The name pronounced will be Hexaaminenickel(II) nitrate(V).
Answer 6: The oxidation number of hydrogen is considered to be Zero because the oxidation state of a simple ion like hydride is equal to the charge on the ion.
Answer 8: The correct formula for potassium diaquatetrachloromolybdate (III) will be K[Mo(H2O)2Cl4].
Answer 10: The oxidation state of silicon in (SiO4)4- is +4.
Answer 11: The example of molecular hydride are H2O, HF, PH3.
