Ab reacts with c2 to yield ac and b. 2ab+c2--> 2ac+2b the molar mass of ab is 75.0 g/mol, the molar mass of ac is 60.0 g/mol, and the molar mass of b is 50.0 g/mol. a) what is the theoretical yield (in grams) of ac from the reaction of 41.0 g of ab? b)if the reaction produced 16.5 g of ac, what was the percent yield?

hey there!

boiling point is the temperature at which the vapor pressure of the liquid equals atmospheric pressure. the vapor pressure of solvent molecules is decreased when a solute is added, so a higher temperature is required to increase the number of solvent molecules in the gas phase above the liquid.

at the freezing point, the vapor pressures of the solid and liquid are equal; a lower temperature is needed to reduce the number of solvent particles above the liquid.

hope this 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.
