Question

30.The type of chemical reaction represented by the following equation is....HBr + NaOH ---> H2O + NaBrSelect one:a. decomposition. b. double displacement.c. single displacement.d. synthesis.

Answer 1

b. Double displacement.

Step-by-step explanation:

It is a double displacement reaction, because in this case, hydrogen atom in HBr is replaced by a sodium atom (from NaOH), and the sodium atom (in NaOH) is replaced by another H atom from HBr molecule, to form H2O.
