Why do the boiling points and melting points of the halogens increase steadily from F_2 to I_2? Why is there an increase in boiling points with larger alkaline molecules? Noble gases have very low boiling points. Explain why. Why is CH_3I have a higher boili...
What is the strongest intermolecular force observed for noble gases? Based on intermolecular forces, which of these substances would have the highest boiling point? What intermolecular force is responsible for the fact that ice is less dense than liquid water? Does an ionic bond have a dipole?
When the precursors have low solubility in water, the pH can also be altered to increase the solubility of the substances. This can be done by altering to acidic conditions with acids such as nitric or hydrochloric acid or to basic conditions with bases such as ammonium or sodium hydroxide. ...

12 electrons per molecule of ethanol. It is non-toxic and its boiling point is relatively high compared to methanol. Ethanol and the higher alcohols have the drawback that their C-C bond rupture for 100% electro- oxidation to carbon dioxide is difficult in the presence of electro-catalyst in...

Why do elements in the same family generally have similar properties? Explain why the noble gases do not react with other elements? Why do elements form compounds? A. Why do the group 8A elements rarely react with other elements? B. Why do we no longer accept Dalton's st...
"Covalent bonds are simple molecular substances consisting of molecules that are held together by weak forces, so these substances have a low melting and boiling point." Explain this concept. Also, what makes bonds stable? Explain why a carbon atom ...
than their boiling point, dispersed in an aqueous solution, subsequently polymerized after dissolution of an appropriate concentration of a heavy salt (e.g., CsCl) in water to equalize densities of droplets and solution. By applying an adequate pressure, the ...
