a. Combination.
b. Double replacement.
c. Decomposition.
d. Single replacement.
e. Combustion.
Work Step by Step
- See Table 7.3 to identify the patterns for each type of reaction.
a. $A + B \longrightarrow AB$
$A = H$, $B = Br$
b. $AB + CD \longrightarrow AD + CB$
$A = Ag$, $B = NO_3$, $C = Na$, $D = Cl$
c. $AB \longrightarrow A + B$
As we can see, $H_2O_2$ is divided between $H_2O$ and oxygen molecules.
d. $A + BC \longrightarrow AC + B$.
$A = Zn$, $B = Cu$ and $C = Cl$
e. This type of reaction occurs when a hydrocarbon $(C_xH_y)$ reacts with oxygen $(O_2)$, to produce carbon dioxide $(CO_2)$ and water.
