Answer:
The equilibrium will shift to the reactants and increase the concentration of CH3COOH
Explanation:
According to Le Chatelier's principle when a system at equilibrium is subjected to a change in temperature, pressure, concentration etc then the equilibrium will shift in a direction to undo the effect of the induced change.
The given reaction is:
CH3COOH ↔ CH3COO-(aq) + H+(aq)
CH3COONa exists as ions i.e. CH3COO- and Na+. Therefore, addition of CH3COONa will introduce more CH3COO- ions into the system as a result the equilibrium will shift to the left i.e. towards the reactants and will produce more of CH3COOH

Answer:
argon-40
Explanation:
The relative atomic mass of Argon is 39.948. This is very close to the mass of argon-40. Usually, the relative atomic mass of an element is the sum of the percentage abundance of each isotope in nature multiplied by its mass. The result of this sum is normally biased towards the isotope with the highest abundance. In the case of argon, argon-40 must have the highest abundance, hence the value of the relative atomic mass.
Argon-40 is the most abundant isotope of argon in nature because the reported atomic mass of argon is closer to 40 atomic mass units.
Given that argon has three naturally occurring isotopes: argon-36, argon-38, and argon-40, compare their masses to determine which one is most likely to contribute the most to the average atomic mass of argon.
The atomic mass of argon is typically given as approximately 39.95 atomic mass units (u). This value is a weighted average of the masses of the different isotopes of argon, taking into account their relative abundance in nature.
Argon-36 has a mass of approximately 36 atomic mass units.
Argon-38 has a mass of approximately 38 atomic mass units.
Argon-40 has a mass of approximately 40 atomic mass units.
Since the reported atomic mass of argon is closer to 40 atomic mass units, it suggests that argon-40 is the most abundant isotope of argon in nature.
