Answer:
3) an applied electric current
Explanation:
An electric source is used in an electrolytic cell.
Answer:
See explanation
Explanation:
According to chemistry libretexts(2020); "The rms velocity is directly proportional to the square root of temperature and inversely proportional to the square root of molar mass. Thus quadrupling the temperature of a given gas doubles the rms velocity of the molecules. ... As the temperature of a gas is increased, the velocity of the molecules is also increased."
Hence considering two gases for which the Vrms of the particles of one is high and that of the other is low, we can conclude that the gas having the higher Vrms is at a higher temperature than the gas having a lower Vrms according to the foregoing.
Because it is made up of sodium, a metal, and carbon, a nonmetal.
