Rank the following compounds in order of decreasing acid strength using periodic trends. rank the acids from strongest to weakest. to rank items as equivalent, overlap them. hcl ; h2s ; hi ; lih

Answer

Hi,

Ranking these compounds in order of decreasing acid strength applying periodic trend will be; HI, HCL, H2S; LiH

Explanation

When ranking these compounds according their acid strength we use the acid association constant (pKa) of each compound at room temperature and observer them.When the constant is lower, the more the acidic the compound is.In the above case, comparing the pKa values;

HI= -10

HCL= -8

H2S=7

LiH=42

Hope this helps!

sup bro, im dumb, but this is what i found xd

"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"
