When Q is equal the initial concentration of the products / the initial concentration of the reactants.
so, Q = [Ag]*[Cl-] and we neglected [AgCl] as it is solid
∴ Q = 10^-6 * 10^-5
= 10^-11
now we will compare the value of Q with the value of Keq:
when Q = Keq so, the system is in equilibrium
and when Q > Keq so, the reaction will go forward (shift to right) to achieve equilibrium.
and when Q< Keq so, the reaction will go left (shift to left) to achieve equilibrium.
when Q = 10^-11 and Keq = 10^20
∴Q< Keq
and the reaction will shift to left.

4. Most likely C
Explanation:
In chemical changes molecules in the reactants interact to form new substances, which mean means are broken up to form new bonds. No atoms are created or destroyed while undergoing the chemical change. In a physical change more like a state of change meaning shape, size or anything that effects how the object looked before then no new substances are formed.
The periodic table is named as such as it is split into groups with the same number of electrons in the outer shell. These groups can also be called periods which is where the table gets its name from.
