When a mixture of ph3, p2, and h2 comes to equilibrium at 873 k according to the reaction
2ph3(g)←−→p2(g)+3h2(g)kp = 398 at 873 k,
where pp2 = 0.414 atm and ph2 = 0.827 atm .

- 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).

it forms an anion that has a larger radius. anions have a negative charge and are larger than the original atom.
