Why does the vapor pressure of water decrease when NaCl is added to it? Use atomic or molecular properties to explain why calcium oxide has a much higher melting point (2580 degrees Celsius) than potassium fluoride (858 degrees Celsius). ...
Indicate which type of bonding would be expected for the following materials and provide sound rationale for your answers: a) Solid Xenon (Xe) b) Calcium fluoride (CaF2) c) Rubber d) Tungsten (W) What is the entropy of pure...
And the most surprising link is that not only do we barely absorb the calcium in cow’s milk (especially if pasteurized), but to make matters worse, it actually increases calcium loss from the bones. What an irony this is! Here’s how it happens. Like all animal protein, milk acidifie...
The structure of fluorite (CaF_2) may be considered as a simple cubic arrangement of fluoride ions with the charge balancing Ca^2+ ions being located in cubic holes. One half-cell in a voltaic cell is constructed from a silver wire electrode in a 0.25 M solution of ...
