J. J. Thomson discovered electron by performing an experiment using cathode ray tubes. High voltage across is applied across two electrodes at that causes a beam of particles to flow from the the negatively-charged electrode that is cathode to the positively-charged electrode that is anode. Properties of the particles, are tested using two oppositely-charged electric plates around the cathode ray. The cathode ray was deflected away from the negatively-charged electric plate and towards the positively-charged plate. This indicated that the cathode ray was composed of negatively-charged particles. And these negatively charged particles are called electrons.
Answer : The volume of required is, 60 L
Explanation :
First we have to calculate the moles of
Now we have to calculate the moles of
The balanced chemical reaction will be:
From the balanced chemical reaction we conclude that,
As, 1 mole of completely react with 2 moles of
So, 0.3 mole of completely react with moles of
Now we have to calculate the volume of required.
Therefore, the volume of required is, 60 L

Phase diagram is a graphical representation of the physical states of a substance under different conditions of temperature and pressure. A typical phase diagram has pressure on the y-axis and temperature on the x-axis. In addition, two states of the substance coexist in equilibrium on the lines or curves
