Atrial of this decomposition experiment, using different quantities of reactants than those listed in the question above produced the following data: volume of o2 produced at room conditions: 280 ml barometric pressure: 740 torr temperature of water: 24oc temperature of o2: 25oc vapor pressure due to water at 24oc: 22.4 torr for the conditions listed above, calculate the volume of o2(g) produced at standard conditions of temperature and pressure. (enter your answer in liters)

Answer asap need to be answered 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.
