Question

what type of reaction is shown below? check all that apply.
$\ce{c_{10}h_{8} + 12o_{2} -> 10co_{2} + 4h_{2}o}$
$\square$ synthesis
$\square$ decomposition
$\square$ combustion

Accepted Answer

# Brief Explanations:
1. **Synthesis Reaction**: A synthesis reaction is when two or more substances combine to form a single product (form: $ A + B
ightarrow AB $). The given reaction has multiple products ($ CO_2 $ and $ H_2O $), so it is not synthesis.
2. **Decomposition Reaction**: A decomposition reaction is when a single compound breaks down into simpler substances (form: $ AB
ightarrow A + B $). The given reaction has a reactant ( $ C_{10}H_8 $) reacting with $ O_2 $, not a single compound breaking down, so it is not decomposition.
3. **Combustion Reaction**: A combustion reaction involves a substance reacting with oxygen ($ O_2 $) to produce carbon dioxide ($ CO_2 $) and water ($ H_2O $), often releasing energy. The reaction $ C_{10}H_8 + 12O_2
ightarrow 10CO_2 + 4H_2O $ fits this: a hydrocarbon ($ C_{10}H_8 $) reacts with $ O_2 $ to form $ CO_2 $ and $ H_2O $.
