A metal cylinder contains 1 mol of nitrogen gas at STP. What will happen to the pressure if
another mole of gas is added to the cylinder but the temperature does not change?

Then pressure will double

Explanation:

PV = nRT

P = nRT / V

If all other variables are kept constant, P will be proportional to n i.e

P1 / n1 = P2 / n2

n = 1

P1 = P

n2 = 2

P2 =?

P1 / n1 = P2 / n2

P /1 = P2/2

Cross multiply

P2 = 2P

Therefore, if an additional 1mole of the gas is added, the pressure will double

- aluminum and copper chloride.

- the chloride ion to separate the aluminum from the oxygen so that the aluminum can react with the copper ions (and the water molecules).
