Ammonia can be produced via the chemicalreaction
\rm n_2 (g) + 3 h_2 (g) \rightleftharpoons 2 nh_3 (g)
during the production process, the production engineer determinesthe reaction quotient to be q_2 = 3.56ã10â4. ifk_2 = 6.02ã10â2, what can besaid about the reaction?
1)the reaction has reached equilibrium.
2)the reaction is not at equilibrium and willproceed to the left.
3)the reaction is not at equilibrium and willproceed to the right.
4)the reaction is not at equilibrium, but it isnot possible to determine whether the reaction needs to proceedright or left to reach equilibrium.

3)The reaction is not at equilibrium and willproceed to the right.

Explanation:

The reaction quotient of an equilibrium reaction measures relative amounts of the products and the reactants present during the course of the reaction at  particular point in the time.

It is the ratio of the concentration of the products and the reactants each raised to their stoichiometric coefficients. The concentration of the liquid and the gaseous species does not change and thus is not written in the expression.

Q < Kc , reaction will proceed in forward direction.

Q > Kc , reaction will proceed in backward direction.

Q = Kc , reaction at equilibrium.

Given that:

Q =

K =

Since, Q < K , reaction is not at equilibrium and will proceed to right, in forward direction.

assuming that your periodic table has eighteen columns, you should highlight   the four elements in the third column from the left of the table.

neutral atoms of elements after calcium contain d electrons. the energy of d orbitals of a particular main shell lies between the energy of the s and p orbitals of the next main shell. for example, electrons in the have energy higher than those in the orbital while lower than those of the orbital.

by the aufbau principle, electrons fill orbitals one at a time, starting from those of the lowest energy. the orbital is therefore filled right after orbitals and before orbitals.  

potassium has electron configuration and calcium . the s orbital of a main shell holds a maximum of two electrons. the next element would thus have the electron configuration and satisfy the requirements.

a neutral atom of the element contains three electrons on top of the most recent noble gas element. it should thus be placed in the third column of the periodic table. both scandium and yttrium would satisfy the conditions. an aufbau diagram indicates that the 4f orbital is filled before the 5d. however, it appears that exceptions exists for both lanthanum and actinium. neutral atoms of the two d-block elements also demonstrate the and should be highlighted as well.
