PPM = Parts Per Million.

1 ppm = 0.0001%

A homogenous mixture is characterized by identical composition.

liquid molecules forming a gas and gas molecule forming a liquid are equal in number

the reaction would shift to favor the side with the most moles of gas. (apex).

Nickel is a metallic solid in the group of transition metals.

Strong Intermolecular Forces attract the molecules

volume increases

solid, liquid, gas phases in equilibrium

Examples: silver, gold, copper, aluminium.

Ammonia solution is a weak base.

The units for the gas constant of 0.0821 are liter-atmospheres/mole-Kelvin

Molality (m) is defined as moles of solute per kg of solvent.Thus, 2 moles/6 kg = 0.33 molal or 0.3 m.
