Answer:
Barium nitrate or silver nitrate based on the anion our solute contains
Explanation:
I assume the situation is that currently the solute is soluble in water and you wish to make it insoluble.
It really depends on the soluble material you have, however, let's look at some specific cases.
- We have a salt in our solution. Addition of any of the three reagents will produce a double displacement reaction, that is, our cation will be replaced by another cation, either sodium, barium or silver cation.
- According to the solubility rules, all sodium salts are soluble, so sodium nitrate won't precipitate our anion.
- In case our solute contains sulfate, carbonate or phosphate, we may use barium nitrate to precipitate it, as barium sulfate, barium carbonate and barium phosphate are insoluble.
- In case our solute contains chloride, then silver nitrate is the way to go to precipitate it in an insoluble form of AgCl. Similarly, silver would form precipitates with carbonate, phosphate, iodide, bromide and slightly soluble silver sulfate (barium is the choice for sulfate, however).
It has mass and takes up space is correct.
Answer:
The one element is substituted in place of other element in compound.
Explanation:
Single replacement:
It is the reaction in which one elements replace the other element in compound.
AB + C → AC + B
For example:
Consider the reaction between zinc and silver nitrate. In this chemical reaction the zinc is substituted in place of silver in silver nitrate compound.
Chemical equation:
2AgNO₃ + Zn → ZnNO₃ + 2Ag
The starting material consist of compound ( AgNO₃) and pure element (Zn).
After reaction a new compound ( ZnNO₃) and pure element (Ag) is generated.
The correct answer is D<span>) remains hazardous for a long time. Nuclear waste stays radioactive for many centuries.
