Agalvanic cell cr(s)cr2 (aq) | sn2*(aq)sn(s) is constructed using a completely immersed cr electrode that weighs 34.7 g and a sn electrode immersed in 500 ml of 1.00 m sn2(aq) solution. a steady current of 0.0758 a is drawn from the cell as the electrons move from the cr electrode to the sn electrode (a) which reactant is the limiting reactant in this cell? enter symbol (b) how long does it take for the cell to be completely discharged? (c) how much mass has the sn electrode gained when the cell is completely discharged? (d what is the concentration of the sn2+(aq) when the cell is completely discharged? assume that the limiting reactant is 100% reacted.

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

this is not my own answer, this is an answer for the same question by the user blahblahmali. i do not claim ownership of this account.

space exploration has led to the development and technological improvement of many everyday items. (if this answer is wrong i will find the right answer) : )

1 is the answer to this problem

it can be observed without changing the identity of the object.

it depends on what substance you're talking about as well as many other factors. in quantum mechanics, the observation of particles affects the observers ability to measure certain properties. for example: you can know the velocity of a particle, but you can't know it's position; or you can know it's position, but not it's velocity. it's like trying to find out where a grain of sand is by throwing other grains of sand at it. once you find out where it is, it's been moved. it's also like trying to find an answer to the question of whether or not a tree falling in a forest makes a sound if nobody is there to hear it. paradoxically, the only way to find out is to be there and hear it.
