For a concentration cell with non-zero voltage, how would you expect the voltage of the cell to change as temperature increases? assume that the multimeter leads are connected so that measured voltages are positive. hint: carefully consider the nernst equation! this question is not as simple as it seems!

How have the greenhouse gasses increased from the year 2000 to 2018

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.
