Question

Indicate what type, or types, of reaction each of the following represents. (Select all that (a) B(OH) 3(aq) + 3 HBr(aq)-BBr3(aq) + 3 H2O() pply) a acid-base combustion double displacement O neutralization O oxidation-reduction O precipitation D single-displacement (b) 2 KIO3(s) 2 KI(s) + 32(g) combustion double displacement neutralization oxidation-reduction single-displacement (c) Fe(NO3) 2(aq) + H2SO4(aq) FeSO4(s) + 2 HNOy(aq) acid-base double displacement neutralization precipitation single-displacement MacBook Air 0 F3 888 F esc 8 3 4 6 2

Explanation / Answer

a) Since reaction consists of an acid ie HBr and base

B(OH) 3, it is acid - base neutralisation reaction.

b) here I is reduced from +5 ( in KIO3) to - 1 in KI and oxygen is oxidized from - 2 to 0.

So, it is a oxidation - reduction reaction.

c) in this reaction, there occurs exchange of species between two compounds ie Fe takes up sulfate from H2SO4 AND hydrogen takes up NO3- from FeNO3-. So it is double displacement reaction.
