A molecule is considered polar if it has an overall dipole moment. The dipole moment of the compound depends if the compound has polar bonds and if the geometry of the compound will permit a net dipole moment. Bond dipole moments occur due to differences in electronegativity....
When chlorine dissolves in water, it produces hypochlorous acid (HOCl) and hydrochloric acid (HCl). The HCl is certainly not good for you, but the toxicity is primarily due to direct oxidation of biomolecules, not to acidity. Carlisle et al.describeit this way: Upon inhalation, Cl2first reac...
One BrCl molecule has a covalent bond where chlorine is more electronegative (electron-greedy) than bromine. This causes ashift in electron density towards chlorine, resulting in a slight negative dipole. Thus bromine obtains a slight positive dipole because it is lacking electron density. ...
Why would sodium react more readily with chlorine? Explain why ionization of water is endothermic. Why does the centrifuge tube need to be filled with ice when performing a sublimation? Why is glass called a supercooled liquid? How would you prepare 1.00 L of a 0.5 M solution of NiCl2 f...
These microbes are removed by “airing”the water and by adding a chemical substance called chlorine氯to the water. This kills all the microbes in the water. After this the water can be safely used for drinking. The third stage is the distribution of the purified water to homes, hospitals,...
Why are trace gases called trace gases? Why is methane such a potent greenhouse gas? What causes trace gases? Why is chlorine a gas at room temperature? Why do metals tarnish? Why is pressure low in capillaries? Suppose that a (small) charged conductor is connected to the ground. Explain...
What are inert gases called? How many noble gases are there? Why is chlorine a nonmetal? Why do ions form covalent bonds (polyatomic ions) if they already have complete valence shells due to their ionizing? Why do elements in the same group of the periodic table have similar properties?
