In an atom, the first energy level can hold

Chemistry
1 answer:
Pepsi [2]3 years ago
3 0

Answer:

2, 8, 18

Explanation:

The number of orbitals for any level of interest n is calculated by a formula o = n^2. Since each orbital contains a maximum of 2 electrons, we can calculate the total number of electrons in an nth orbital by e = 2n^2.

  • As a result, the first energy level for n = 1 can hold a maximum of 2n_1^2 = 2\cdot 1^2 = 2 electrons,
  • The second energy level can hold a maximum of 2n_2^2 = 2\cdot 2^2 = 8 electrons,
  • The third energy level can hold a maximum of 2n_3^2 = 2\cdot 3^2 = 18 electrons.

What is the equilibrium constant, KC if the reaction is a gas phase reaction? (Ans.: Gas: KC = 0.328 dm3/mol)
valentina_108 [34]

Answer:

Equilibrium constant Kc = Qc = quotient of reactant(s) and product(s)

Kc = [C]x[D]y..../[A]m[B]n..... = 0.328dm3/mol, where [C]x[D]y is the product and [A]m[B]n is the reactant(Both in gaseous states)

Explanation:

When a mixture of reactants and products of a reaction reaches equilibrium at a given temperature, its reaction quotient always has the same value. This value is called the equilibrium constant (K) of the reaction at that temperature. As for the reaction quotient, when evaluated in terms of concentrations, it is noted as Kc.

That a reaction quotient always assumes the same value at equilibrium can be expressed as:

Qc (at equilibrium) = Kc =[C]x[D]y…/[A]m[B]n…

This equation is a mathematical statement of the law of mass action: When a reaction has attained equilibrium at a given temperature, the reaction quotient for the reaction always has the same value.
