Hi friends thanks for your suggetsions. I think steve's suggestion is for elemental analyis like N or S but not for Pd. For this what I was planing and JohnWW...
With a metal such as Pd, you may have trouble completely digesting the Pd, especially if the sample is a large percentage of Pd (like a solubilized Pd-ligand...

Hi folks Can anyone explain what type of forces you need to include in a molecular mechanics calculation of the defect energy when a Ca(2+) ion in the solid...
First, what computer program are you using to compute molecular mechanics. These are empirical programs, and you have to know what core potentials to plug into...
There are NO "molecular mechanics" involved, because it is a purely ionic compound, existing as a crystalline salt. Just off the top of my head, I think CaO...

Here's some information from Wikopedia on hard water. Soft water also contains calcium, but not as much. Hard water makes better whiskey, possibly why they...
Brian is of course correct. Some "temporary" hard water, as we call it in the U.S., has water-soluble calcium bicarbonate, Ca(HCO3)2. This water can be...
