Answer:
The total mass of four moles of helium (He) is 16.0104 grams.
Explanation:
Answer:
[Ni(CN)4]2- square planar
[NiCl4]2- tetrahedral
Explanation:
For a four coordinate complex such as [Ni(CN)4]2- and [NiCl4]2-, we can decide its geometry by closely considering its magnetic properties. Both of the complexes are d8 complexes which could be found either in the tetrahedral or square planar crystal field depending on the nature of the ligand.
CN^- being a strong field ligand leads to the formation of a square planar diamagnetic d8 complex of Ni^2+. Similarly, Cl^- being a weak field ligand leads to the formation a a tetrahedral paramagnetic d8 complex of Ni^+ hence the answer given above.
Answer:
So she is very anxious because she has to wait 345600 seconds
Explanation:
60 second = 1 minute
60 minute = 1 hour
1 hour has 3600 seconds (60*60)
24 hour = 1 day
3600 second * 24 hours =
1 day has 86400 seconds so in four days
86400 * 4 = 345600
