Answer
a. Double replacement.
b. Combination.
c. Combustion.
d. Single replacement.
e. Decomposition.
Work Step by Step
- See Table 7.3 to identify the patterns for each type of reaction.
a. $AB + CD \longrightarrow AD + CB$
$A = Cu$, $B = O$, $C = H$, $D = Cl$
b. $A + B \longrightarrow AB$
$A = Al$, $B = Br$
c. This type of reaction occurs when a hydrocarbon $(C_xH_y)$ reacts with oxygen $(O_2)$, to produce carbon dioxide $(CO_2)$ and water.
d. $A + BC \longrightarrow AC + B$.
$A = C$, $B = Fe$ and $C = O$
e. $AB \longrightarrow A + B$
As we can see, one single reactant gives two different products as a result of this reaction. Thus, it is classified as a decomposition reaction.
