How many milliliters of 3.0 M H2SO4 are needed to make 450 mL of 0.10 M H2SO4?
never [62]

Answer:  97.2223 ml

Explanation:

The rule that we will use to solve this problem is:

M2*V1 = M2*V2 where:

M1 is the initial concentration = 3.5 m

V1 is the initial volume = 0.25 l = 250 ml

M2 is the final concentration = 9 m

V2 is the final volume that we need to find

Substitute with the givens in the above equation to get V2 as follows:

3.5*250 = 9*V2

V2 = <em><u>97.2223 ml</u></em>

Will strontium bromide and potassium sulfate give a precipitate
antiseptic1488 [7]

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:

Sr(Br)_2(aq)+K_2SO_4(aq)\rightarrow 2KBr(aq)+SrSO_4(s)

Note: (aq) stands for aqueous and (s) stands for solid and here it's precipitate.
