Based on the understanding of the mechanism of a single displacement reaction, which of the following chemical equations represent a single displacement reaction? Select all that apply. A. NaCl + AgNO3 → NaNO3 + AgCl
B. Cu + AgNO3 → CuNO3 + Ag
C. 2NaBr + Cl2 → 2NaCl + Br2
D. F2 + 2NaBr → 2NaF + Br2
E. KOH + HCl → KCl + H2O

B. Cu + AgNO3 → CuNO3 + Ag

C. 2NaBr + Cl2 → 2NaCl + Br2

D. F2 + 2NaBr → 2NaF + Br2

Explanation:

There are several types of reactions in chemistry, of which one of them is the SINGLE DISPLACEMENT REACTION. Single displacement reaction is that reaction in which only one element in a compound is displaced/replaced by another element.

The following reactions given in this question are examples of single displacement reactions;

- Cu + AgNO3 → CuNO3 + Ag

- 2NaBr + Cl2 → 2NaCl + Br2

- F2 + 2NaBr → 2NaF + Br2

* In the first reaction, silver (Ag) is displaced by copper (Cu)

* In the second reaction, bromine (Br) is displaced by chlorine (Cl)

* In the third reaction, bromine (Br) is displaced by fluorine (F)
