Answer:
The MAD of city 2 is less than the MAD for city 1, which means the average monthly temperature of city 2 vary less than the average monthly temperatures for City 1.
Explanation:
For comparing the mean absolute deviations of both data sets we have to calculate the mean absolute deviation for both data sets first,
So for city 1:
Now to calculate the mean deviations mean will be subtracted from each data value. (Note: The minus sign is ignored as the deviation is the distance of value from the mean and it cannot be negative. For this purpose absolute is used)
The deviations will be added then.
So the mean absolute deviation for city 1 is 24 ..
For city 2:
Now to calculate the mean deviations mean will be subtracted from each data value. (Note: The minus sign is ignored)
The deviations will be added then.
So the MAD for city 2 is 11.33 ..
So,
The MAD of city 2 is less than the MAD for city 1, which means the average monthly temperature of city 2 vary less than the average monthly temperatures for City 1.

Explanation:
It really depends what salt silver cation makes in the context of this problem. In this problem, we have a single displacement reaction in which copper metal displaces silver cation from a salt to produce silver metal. Based on the charge of the anion in the salt, we may have differently balanced chemical equations.
Since silver cation mostly makes insoluble salts and we need a soluble one for a single displacement reaction, we'll use silver nitrate as our example, as it's the most common soluble silver salt. We have the following reaction:
Notice that 1 mole of copper reacts to produce 2 moles of silver. This may be mathematically written as:
Express moles as a ratio between mass and molar mass:
Rearrange the equation for the mass of silver metal:
Substitute the given data:
It’s called neutralization. The alkali has neutralized the acid by taking away the H+ ions and then turning them into water.
