Rank the following compounds in order of decreasing acid strength using periodic trends. Rank the acids from strongest to weakest. a. HCl
b. H2S
c. HBr
d. BH3

HBr > HCl > H2S > BH3

Explanation:

In many acids, the magnitude of electronegativity of the nonmetal determines the strength of the acid. The less electronegative the non-metal is, the stronger the acidity of the acid.

This is because the less electronegative the nonmetal is, the more easily the H-X bond is broken since it is longer and weaker.

This explains the order of acid strength shown in the answer above.

a pan containing water is placed in a positio n where it is exposed to a 10 mile per hour wind. the pan contains a uniform depth of 1.27 cm of water, is quite wide, and has a length of 2.44 m in the wind direction. the water in the pan is at a constant temperature of 15.5 °c.
