Predict the products formed from the following set of reactants. FeSe(s) + HCl(aq) → A)Se( s)+ FeCl ₂( aq) B)SeCl ₂( s)+ Fe( s)+ H ₂( g) C)FeH ₂( s)+ SeCl ₂( l) D)H ₂Se( g)+ Fe( s)+ Cl ₂( g) E)H ₂Se( g)+ FeCl ₂( aq)

Question

Quizplus · Accepted Answer

The reaction between FeSe and HCl will produce hydrogen selenide gas (H2Se) and iron chloride (FeCl2). The balanced equation is:
FeSe(s) + 2HCl(aq) → H2Se(g) + FeCl2(aq)
However, the options given have different chemical formulas for hydrogen selenide. Option E has the correct formula of H2Se(g) and also includes FeCl2(aq) as a product.
