The balanced equation will be :
To calculate the moles, we use the equation:
moles of
According to stoichiometry :
2 moles of require = 3 moles of
Thus 0.544 moles of require=
of
Mass of
Thus 131 g of bromine is required.
Answer:- Yes, strontum bromide and potassium sulfate gives a precipitate of strontium sulfate.
Explanations:- As per the solubility rules, all compounds of alkali metals are soluble.
Sulfate of most of the alkaline earth metals like Ca, Ba and Sr are insoluble.
A double displacement reaction takes place when strontium bromide and potassium sulfate are mixed and a precipitate of strontium sulfate is formed:
Note: (aq) stands for aqueous and (s) stands for solid and here it's precipitate.
