2CuI (s) + I₂ (aq) → 2 Cu⁺² (aq) + 4 I⁻ (aq)
When writing an equilibrium expression, we use the following values:
A (aq) + 3B (aq) → 2C (aq) + 2D (aq)
The numbers were arbitrary molar equivalents and the uppercase letters are the molecules in the reaction. The species used in the equilibrium expression but all be in the same state, e.g., solid, liquid, aqeuous.
Kc = [C]²[D]² / [A][B]³
We write the formula by taking the concentration of the products, each to the power of their molar equivalent, and multiply them together. We then divide the products by the concentration of the reactants, also to the power of their molar equivalent.
Going back to the initial equation given, we can now write a Kc expression.
Kc = [Cu⁺²]²[I⁻]⁴ / [I₂]
It should be noted that the CuI (s) in the reaction was left out of the Kc expression. Pure solids and liquids are left out of the expression and only the aqueous species are included. The reason being that, in this case, solid CuI does not affect the amount of reactant at equilibrium. Therefore, we just leave the concentration for [CuI] = 1, and remove it from the expression.

Answer:
His first law states that every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force. This is normally taken as the definition of inertia. ... The amount of the change in velocity is determined by Newton's second law of motion.
