Consider a galvanic cell that operates at 298 K and is based on the following redox reaction: Fe(s) + Sn2+(aq) → Fe2+(aq) + Sn(s) E° = 0.30 V If the cell is initially at standard conditions ([Sn2+] = [Fe2+] = 1.00 M), what are the concentrations of Sn2+ and Fe2+ when the cell potential has fallen 10% to 0.27 V?

there is none because earth is stationary and flat.

< > according to newton's third law of motion, forces always act in equal but opposite pairs. another way of saying this is for every action, there is an equal but opposite reaction.< >

hey there!

mass = 6.75 g

volume =   9 cm³

therefore:

d = mass / volume

d   = 6.75 / 9

d = 0.7 g/cm³

answer b

the right answer is c i just did the question.
