During a laboratory experiment 3.81g of NaHCO3 was thermally decomposed to generate 2.86 grams of carbonic acid (H2CO3). Calculate the percent yield of carbonic acid for the reaction. Show all work for the calculation (10 points). NaHCO3 → Na2CO3 + H2CO3

H2CO3

Explanation:

tahts hard hope u find the answer :)

there are two significant figures.

c is having 4 valence electrons and is bonded to three hydrogens and one sulphur atom, therefore, the number of bond pair is equal to four. as all the valence electrons are used in forming the bonds so, there is no lone pair left on carbon.

s is having 6 valence electrons and is bonded to one other sulfur atom and one carbon atom, therefore, the number of bond pair is equal to 2. as only two valence electrons are used in forming the bonds so, four electrons are left. therefore, two lone pairs are present on s.
