Question

classify the following reaction: cl₂ + zni₂ → zncl₂ + i₂. combustion synthesis decomposition single displacement double displacement

Explanation:

Step1: Recall reaction - type definitions

A combustion reaction involves a substance reacting with oxygen to produce heat and light. A synthesis reaction is when two or more substances combine to form one product. A decomposition reaction is when one compound breaks down into two or more simpler substances. A single - displacement reaction is of the form $A + BC
ightarrow AC + B$, where one element replaces another in a compound. A double - displacement reaction is of the form $AB+CD
ightarrow AD + CB$, where the cations and anions of two different compounds exchange places.

Step2: Analyze the given reaction

The reaction is $\mathrm{Cl}_{2}+\mathrm{ZnI}_{2}
ightarrow\mathrm{ZnCl}_{2}+\mathrm{I}_{2}$. Here, chlorine ($\mathrm{Cl}_{2}$) is an element that replaces iodine ($\mathrm{I}$) in the compound $\mathrm{ZnI}_{2}$. It follows the pattern $A + BC
ightarrow AC + B$ where $A=\mathrm{Cl}_{2}$, $B = \mathrm{I}$, and $C=\mathrm{Zn}$.

Answer:

single displacement
