At each end of wthe container there is a piston. Piston A has a smaller area than piston B.
(a) 0
Rebekah pushes on the pedal. This produces a force of 200 N on
piston A.
Calculate the pressure that piston A exerts on the liquid.
Give the unit.

How can one make a supersaturated solution? (apex)

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.

Is this correct if not can u correct me
