Answer

Answer:

solution A solution B Does a precipitate form when A and B are mixed? empirical formula of precipitate
silver nitrate sodium sulfate yes $\ce{Ag2SO4}$
potassium hydroxide iron(II) chloride yes $\ce{Fe(OH)2}$
manganese(II) bromide nickel(II) acetate no

Explanation:

Step1: Write reaction for silver nitrate and sodium sulfate

$\ce{2AgNO3(aq) + Na2SO4(aq)\rightarrow Ag2SO4(s)+ 2NaNO3(aq)}$; silver sulfate is insoluble.

Step2: Write reaction for potassium hydroxide and iron(II) chloride

$\ce{2KOH(aq)+FeCl2(aq)\rightarrow Fe(OH)2(s) + 2KCl(aq)}$; iron - (II) hydroxide is insoluble.

Step3: Write reaction for manganese(II) bromide and nickel(II) acetate

$\ce{MnBr2(aq)+Ni(CH3COO)2(aq)\rightarrow Mn(CH3COO)2(aq)+NiBr2(aq)}$; all products are soluble.
