Answer:
.
Explanation:
Magnesium chloride and silver nitrate reacts at a ratio:
.
In reality, the nitrate ion from silver nitrate did not take part in this reaction at all. Consider the ionic equation for this very reaction:
.
The precipitate silver chloride is insoluble in water and barely ionizes. Hence, isn't rewritten as ions.
Net ionic equation:
.
Calculate the initial quantity of nitrate ions in the mixture.
.
Since nitrate ions do not take part in any reaction in this mixture, the quantity of this ion would stay the same.
.
However, the volume of the new solution is twice that of the original nitrate solution. Hence, the concentration of nitrate ions in the new solution would be of the concentration in the original solution.
.
Answer:
Explanation:
Number of molecules of water =
= Avogadro's number =
Number of moles is given by
The number of moles of water is .
Answer : The mass of is, 295.323 grams
Solution :
First we have to calculate the moles of .
Now we have to calculate the moles of NaBr.
The balanced chemical reaction is,
From the balanced reaction we conclude that
As, 2 moles of react with 2 moles of
So, 2.87 moles of react with 2.87 moles of
Now we have to calculate the mass of NaBr.
Therefore, the mass mass of is, 295.323 grams
