Re: Determining Oxidation [ENDORSED]
The cation is neutrally charged the Chlorate anion has a charge of -1, the cyano ligand has a -1 charge, the ethylenediamine ligand is neutral, and the Chloride ligand has a -1 charge. These add up to -3 so to make the cation neutral the metal must have a charge of +3.

Re: Atomic absorption of energy
When an electron goes to a higher energy level the electron absorbs energy. When the electron goes back down to a lower energy level, the energy becomes more negative as it is becoming less excited. When it goes to a lower energy level it emits a photon, in other words the difference in the energy i...

Re: Uncertainty
In the new workbooks, the answer is different. In the key it says the uncertainty in position is 3.2x10^-32 m. But with the calculations you gave the answer is different. But the question is still the same. What is the right answer?
