Question

Which of the following chemical reactions is a single displacement reaction?

A. 2Na + O2→
Na2O
B. 2A1 + 3Zn(NO3)2 2AI(NO3)3 + 3Zn​
C. Pb(NO3)2 + 2KBr → PbBr2 + 2KNO3
D. 2Fe(OH)3 Fe2O3 + 3H2O

Answer 1

B. 2A1 + 3Zn(NO3)2 --> 2AI(NO3)3 + 3Zn​

Step-by-step explanation:

Answer 2

B. 2A1 + 3Zn(NO3)2 --> 2AI(NO3)3 + 3Zn​

Step-by-step explanation:

In the chemical equation, you can see that 2Al replaced 3Zn with (NO3)3 in the product, thus it is a single displacement reaction.
