Answer:
Partial pressure for each of the three gases, in the mixture is 15 atm
Explanation:
Remember that the total pressure of a mixture, is the sum of partial pressures from the gases contained in the mixture.
Our total pressure = 45 atm
The 3 gases have the same pressure, so we can propose this equation:
3x = 45 atm
where x is the partial pressure for each of the three gases.
x = 45/3 → 15 atm
This is a difficult task because zinc is much more active than copper and could hardly be passivated. ... The sur- face immediately turns white (the color of copper(I) iodide) and the yellow-brown color of iodine quickly fades. Rinse the coin with water, brighten it with polish and cloth and begin the whole process again.N

Answer:
was difficult to place isotopes of elements as they have the same chemical properties but different atomic masses. It was not possible to predict how many elements could be discovered between two heavy elements as the rise in atomic mass is not uniform.
