Which of the following reactions shows that the formation of SO2 releases 296.8 kJ/mol?
O A. S(s) + O(g) → SO2(g) + 296.8 kJ
O B. S(s) + O2(g) → SO2(g) + 296.8 kJ
O C. S(s) + 20(g) + 296.8 kJ → SO2(9)
O D. S(s) + O2(g) + 296.8 kJ → SO2(g)

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.
