In an electrochemical cell, Q = 0.010 and K = 855. What can you conclude about Ecell and Ecell? a) Ecell is positive and Ecell is negative. b) Ecell is negative and Ecell is positive. c) Ecell and Ecell are both negative. d) Ecell and Ecell are both positive.

explanation:

detials on each model with digrams

the answer would be a

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation
