Answer:
Precipitate formation
Step-by-step explanation:
Chemical change:
The changes, that occur due to change in the composition of a substance and result in a different compound is known as chemical change.
These changes are irreversible
These changes occur due to chemical reactions
Chemical reaction:
Cl₂(g) + 2NaBr(aq) → 2NaCl(s) + Br₂(g)
when chlorine react with sodium bromide, sodium chloride and bromine gas is formed. The formation of solid sodium chloride is actually indication of chemical change because precipitates are formed during chemical reaction.
The given reaction is single displacement reaction.
Single replacement:
It is the reaction in which one elements replace the other element in compound.
AB + C → AC + B
