Answer:

Explanation:
When copper metal is dipped into an aqueous solution of
, copper nitrate (
) is formed. This is type of displacement reaction because copper metal displaces silver from its salt. As only one ion is being displaced, therefore, it is a single displacement reaction.
Copper displaces silver as it is more reactive than silver. This can be confirmed by position of copper and silver in reactivity series. Elements above in the reactive series displaces elements present below from their salts.
The molecular equation is as follows:

Now, write the ionic equation as follows:

Cancel the common terms,

Answer:
it would have caused organisms to move in search of food and better conditions.
Answer:
![[Cl^-]=232.3\frac{mgCl^-}{L}](https://tex.z-dn.net/?f=%5BCl%5E-%5D%3D232.3%5Cfrac%7BmgCl%5E-%7D%7BL%7D)
Explanation:
Hello,
In this case, we can represent the chemical reaction as:

In such a way, since the mass of the obtained silver chloride is 93.9 mg, we can compute the chloride ions in the ground water by using the following stoichiometric procedure whereas the molar mass of chloride ions and silver chloride are 35.45 g/mol and 143.32 g/mol respectively:

Finally, for the given volume of water in liters (0.100L), we compute the required concentration:
![[Cl^-]=\frac{23.2mgCl^-}{0.100L}\\](https://tex.z-dn.net/?f=%5BCl%5E-%5D%3D%5Cfrac%7B23.2mgCl%5E-%7D%7B0.100L%7D%5C%5C)
![[Cl^-]=232.3\frac{mgCl^-}{L}](https://tex.z-dn.net/?f=%5BCl%5E-%5D%3D232.3%5Cfrac%7BmgCl%5E-%7D%7BL%7D)
Best regards.
