Answer: The equations are written below.
Explanation:
Single displacement reaction is defined as the reaction in which more reactive element displaces a less reactive element from its chemical reaction.
[tex]AB+C\rightarrow CB+A[/tex]
Element C is more reactive than element A.
Double displacement reaction is defined as the reaction in which exchange of ions takes place.
[tex]AB+CD\rightarrow CB+AD[/tex]
Decomposition reaction is defined as the reaction in which a large substance breaks down into smaller substances.
[tex]AB\rightarrow A+B[/tex]
Synthesis reaction is defined as the reaction in which smaller substances combine in their elemental state to form a larger substance.
[tex]A+B\rightarrow AB[/tex]
For the given options:
- Option 1: Iron (III) bromide reacting with ammonium sulfide to produce iron (III) sulfide and ammonium bromide
The balanced chemical equation follows:
[tex]Fe_2(SO_4)_3+3(NH_4)_2S\rightarrow Fe_2S_3+3(NH_4)_2SO_4[/tex]
This is considered as double displacement reaction.
- Option 2: Calcium oxide reacting with diphosphorus pentoxide to produce calcium phosphate
The balanced chemical equation follows:
[tex]3CaO+P_2O_5\rightarrow Ca_3(PO_4)_2[/tex]
This is considered as synthesis reaction.
- Option 3: Magnesium chloride reacting with silver nitrate to produce magnesium nitrate and silver chloride
The balanced chemical equation follows:
[tex]MgCl_2+2AgNO_3\rightarrow 2AgCl+Mg(NO_3)_2[/tex]
This is considered as double displacement reaction.
- Option 4: Sodium carbonate reacting with sulfuric acid to produce sodium sulfate, carbon dioxide and water
The balanced chemical equation follows:
[tex]Na_2CO_3+H_2SO_4\rightarrow Na_2SO_4+CO_2+H_2O[/tex]
This is considered as double displacement reaction.
- Option 5: Iron(II) sulfide reacting with hydrochloric acid to produce iron (II) chloride and hydrogen sulfide
The balanced chemical equation follows:
[tex]FeS+2HCl\rightarrow FeCl_2+H_2S[/tex]
This is considered as double displacement reaction.
Hence, the reactions are written above.
