Calculate a shm for this equation. round to the
nearest whole number
naoh(aq) + hcl(aq) → h2o(1) + nacl(aq)
son = 49.8 j/mol k
ska = 56.5 j/mol k
sko = 69.91 j/mol k
suci = 115.5 j/mol k
a san = | i jk

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.
