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

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:

The given chemical reaction is:

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.

The given chemical reaction is:

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

The given chemical reaction is:

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

every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. therefore, there must be the same number of atoms of each element on each side of a chemical equation.
