A barium hydroxide solution is prepared by dissolving 3.33 g of Ba(OH)2 in water to make 29.9 mL of solution. What is the concentration of the solution in units of molarity? concentration:
M
The barium hydroxide solution is used to titrate a perchloric acid solution of unknown concentration. Write a balanced chemical equation to represent the reaction between barium hydroxide and perchloric acid.
chemical equation:

If 15.1 mL of the barium hydroxide solution was needed to neutralize a 7.97 mL aliquot of the perchloric acid solution, what is the concentration of the acid?
concentration: M

it’s previous models   because when i picked that son of a gun’s answer it was wrong look for previous models because they might make it a different letter  

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.

explanation:

0.07 g/cm³

1.37 g/cm³
