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.

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.
