Calculate the pH and percent ionization of a HC2H3O2 solution with a concentration of 0.500 M. (Ka = 1.8 x10-5)

I can not see the file

Explanation:

the ozone layer acts as a filter for the shorter wavelength and highly hazardous ultraviolet radiation (uvr) from the sun, protecting life on earth from its potentially harmful effects. when the sky is clear, there is an inverse relationship between stratospheric ozone and solar uvr measured at the earth's surface.

catya your not at all which answer i've seen you do this on another question!
