The net ionic equation is
Ag⁺(aq) +Cl⁻(aq) → AgCl(s)
Explanation
AgNO₃ (aq) + KCl (aq)→ AgCl(s) +KNO₃(aq)
from above molecular equation break all soluble electrolyte into ions
Ag⁺(aq) +NO₃⁻ (aq) + K⁺(aq) +Cl⁻(aq) → AgCl (s) + K⁺(aq) + No₃⁻(aq)
cancel the spectator ions in both side of equation =K⁺ and NO₃⁻ ions
The net ionic equation is therefore
= Ag⁺(aq) + Cl⁻(aq) → AgCl(s)
Certain conditions provide less than 10% yield of NH3 at equilibrium. Which statement describes this equilibrium?
This equilibrium has a low yield of NH3 and can be improved by adjusting the conditions and using the principles of Le Chatelier.
This equilibrium can be described as an equilibrium with a low yield of NH3. The fact that less than 10% yield of NH3 is obtained suggests that the forward reaction (N2(g) + 3H2(g) -> 2NH3(g) + energy) is not favored under the given conditions. To increase the yield of NH3, the conditions can be adjusted to shift the equilibrium towards the product side.
The Le Chatelier's principle can be applied to achieve a higher yield of NH3. One possible way is to increase the concentration of the reactants (N2 and H2) or decrease the concentration of the product (NH3). Another way is to increase the temperature, as this reaction is exothermic. By increasing the temperature, the equilibrium will shift in the reverse direction to consume the excess energy.
In summary, this equilibrium is characterized by a low yield of NH3, which can be improved by adjusting the conditions and using the principles of Le Chatelier.

(2) an isotope (4) a compound
Any substance composed of two or more elements that are chemically combined in a fixed proportion is known as a Compound. Thus, it's D.
Elements may be defined as any substance that cannot be disintegrated into more superficial substances by standard chemical processes.
In chemistry, an isomer may be defined as those molecules which the same molecular formulas, but different arrangements of atoms.
An Isotope may be defined as an atom that bears the same atomic number and chemical identities but possesses a different atomic mass.
A solution may be defined as a homogeneous mixture of one or more solutes disbanded in a specific solvent.
Therefore, the correct option for this question is D.
