A chemical reaction between 19.68g of Calcium nitrate and Sulfuric acid was carried out so as to produce 15.18g of Calcium Sulfate and Nitric Acid. Calculate the percentage yield of Calcium sulfate produced. Molor Masses:
Ca = 40 g/mol
N = 14 g/mol
O = 16 g/mol
S = 32 g/mol

i'm wiling to try and you : )

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.
