Indicate what type, or types of reaction ech of the following represents:
(a)Ca + Br2 -> CaBr2
(b)Ca(OH)2 + 2HBr -> CaBr2 + 2H2O
(c)C6H12 + 9O2 -> 6CO2 +6H2O

Respuesta :

Answer:

For a: The reaction is a type of synthesis reaction.

For b: The reaction is a type of double displacement reaction

For c: The reaction is a type of combustion reaction.

Explanation:

  • For a:

The given chemical reaction is:

[tex]Ca+Br_2\rightarrow CaBr_2[/tex]

The above reaction is a type of synthesis reaction because calcium and bromine are combining in their elemental state to form a calcium bromide compound.

  • For b:

The given chemical reaction is:

[tex]Ca(OH)_2+2HBr\rightarrow CaBr_2+2H_2O[/tex]

The above reaction is a type of double displacement reaction because here exchange of ions takes place.

  • For c:

The given chemical reaction is:

[tex]C_6H_{12}+9O_2\rightarrow 6CO_2+6H_2O[/tex]

The above reaction is a type of combustion reaction because a hydrocarbon is reacting with oxygen gas to produce carbon dioxide and water molecule.
