Alumina is a finely-ground mineral composed of oxide and sulfide minerals. It is a black, brittle mineral that occurs naturally in various locations worldwide. It is also utilized in the production of glass and porcelain. Furthermore, alumina is safe to use in cosmetics as it does not contai...
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 pur...
Alternatively he may suggest using mouthwashes, toothpastes or filling materials that contain fluoride, calcium and phosphates. When decay reaches the dentin, there is no turning back. A small cavity can be repaired with either an amalgam filling (composed of silver and other metals) or a ...
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 ...
The melting point of the substance is described as the temperature at which the substance changes from its solid form to the liquid form. At the melting point, the solid and the liquid form of the substance exist in equilibrium. Answer and Explanation: The Magnesium oxide(MgO) and Calcium ...
