Answer questions a-c about the bronsted acid-base reaction below using the identifying letters a-d below each structure. the pka's for the acids of interest are: phenol (pka = 9.9), and carbonic acid (pka = 6.4). a) the stronger acid is b) its conjugate base is c) the species that predominate at equilibrium are (two letters, e. g. ac)

a  H2CO3 b HCO3- and c H+ and HCO3-

Explanation:

As the pKa value of phenol is more than that of carbonic acid(H2CO3), the carbonic acid will have high Ka value than that of phenol.

  The acid that contain high Ka value act as stong acid.From that point of view H2CO3 is a strong acid than phenol as the Ka value of carbonic acid is greater than that of phenol.

  The conjugate base of H2CO3 is bicarbonate ion(HCO3-)

c The species that predorminates at equilibrium are H+ and HCO3-

answer; i do believe the correct answer is (river); /// good luck

answer: any goods being imported from another country may be subject to issued by the federal government are tariffs

explanation:  

tariffs are a tax on anything that are imported from abroad. government use them to protect and boost their local industries and the thought is that they encourage consumers to buy local instead of importing and they will hope will protect jobs and economy in the country that implements them
