For the reaction n2(g) + 3h2(g) 2nh3(g), what will happen if more ammonia gas is added? a.)there will be a shift toward the products. b.)the value for keq will change. c.)there will not be a shift in equilibrium. d.)there will be a shift toward the reactants.

The correct answer is option d.

Explanation:

Any change in the equilibrium is studied on the basis of Le-Chatelier's principle.Whenever we increase the concentration of any species in an equilibrium ,there is a shift in an equilibrium in the direction where decrease in concentration is taking place.

So, when we add ammonia gas into the system , equilibrium will get shift in backward direction that is towards reactants.

since the atomic number is the number of protons in the nucleus, as we move to the left on the periodic table, the electrostatic pull between the nucleus and the valence electron shell decreases. as we move down a group (vertical column), the valence shell energy level gets further and further from the nucleus.

how do models compare to real-world objects?

d. most models represent a real-world object in a simpler way.
