Why is MgF_2 polar? Why Boiling point of water is more than hydrogen fluoride(HF)? Why do metals conductivity rate reduces with increase in temperature? Sodium metal is soft whereas sodium chloride is very hard. Explain why. Why does decomposed aspirin melt faster?
Why do we use a minimum amount of solvent to dissolve the solid that is to be recrystallized? Why do alcohols dissolve in concentrated HCl? why are alkyl halides insoluble in concentrated HCl? Explain why methyl alcohol is soluble in water in all proportions, while stearyl alcohol CH3(CH2)16...
Polar compounds are formed when the constitute atoms do not share electrons equally, thus a form of opposite charges on different sides. Nonpolar compounds, on the other hand, are formed when the atoms share the electrons equally, thus the electrons are evenly distributed with the molecule having...
The stochastic boundedness of the random events does not imply the probability of random variables converging at some point but the other way round is absolutely true, that is, the convergence of random variables in probability do imply stochastic boundedness....
Why do we use UV-Vis spectroscopy?Explain why UV-B radiation can be damaging to us and our environment if it reaches the earth in higher quantities than it does now.Explain why it is beneficial to us to have UV-A radiation reach the surface of the earth....
Why do ionic compounds have high melting points? Explain why a liquid should not be distilled to dryness. Why is MgF_2 polar? Discuss mixed melting points and why they are useful. Explain why KNO_3 will not dissolve in hexane (C_6H_{14}) ? Why is activated carbon useful duri...
Why is MgF_2 polar? Why are Group 7A (17) elements found in many compounds but not Group 8A (18) elements? Why don't molecular compounds conduct electricity, but ionic compounds do? Why do atoms hybridize? Why are there so many more carbon compounds than the number of compounds made up...

Does MgF2 or MgO have bigger lattice energy? Explain.Why do ionic compounds have high melting points?Why is the melting point of iron greater than that of sodium?Will 10% MgO increase the strength of a sample of 90% SiO2?Why is the melting point of an element lower than its boiling ...
Why do we not include a term for the solid in a solubility product expression? Why does sugar dissolve well in water? Why does a solute dissolve only to a particular extent in water? Why would SO2 go down in solubility when temperature increases?
