A gravimetric analysis was performed according to the following equation: BaCl2(aq) + 2AgNO3(aq) → Ba(NO3)2(aq) + 2AgCl(s) 2.00g of BaCl2 was dissolved into water and an excess of AgNO3 was added. How many grams of the AgCl do you expect to collect? {Ba: 137.33 g/mol; Cl: 35.45 g/mol; Ag: 107.87 g/mol}

explanation:

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.
