Calculate the total quantity of heat required to convert 25.0 g of liquid ccl4(l) from 35.0°c to gaseous ccl4 at 76.8°c (the normal boiling point for ccl4). the specific heat of ccl4(l) is 0.857 j/(g ∙ °c) its heat of fusion is 3.27 kj/mol and its heat of vaporization is 29.82 kj/mol.

Answer asap need by wednesday morning explain how a buffer works, using an ethanoic acid/sodium ethanoate system including how the system resists changes in ph upon addition of a small amount of base and upon addition of a small amount of acid respectively. include the following calculations in your i. calculate the ph of a solution made by mixing 25cm3 0.1m ch3cooh and 40cm3 0.1m ch3coo-na+. [ka = 1.74 x 10-5 m] ii. calculate the ph following the addition of a 10cm3 portion of 0.08 m naoh to 500cm3 of this buffer solution. iii. calculate the ph following the addition of a 10cm3 portion of 0.08 m hcl to 200cm3 of the original buffer solution.
