That will make a difference. If you are on a 7-10 regimen with the amoxicillin, it will probably be another couple of days before oyu start to tell a difference. You evidently have a sinus infection. The throat soreness may be due to it beginning to drain....post nasal drip can cause sore throats.
Water is about 33% ionic. Linus Pauling discusses the ionic character of water in his famous The Nature of the Chemical Bond at pages 100-101. Pauling says as a first approximation water should be considered as having contributions from four resonance structures: 37% $\ce{H-O-H}$. 24% $\ce{(H-O)- ~H+}$. 24% $\ce{H+ ~(O-H)-}$.
Specifically, what type of chemical bond is found within a water molecule? What type of bond forms between adjacent water molecules? Explain how these two bonds are different from one another.
