Question
_________ is used for making electric switches of various kinds, taps, statues, household utensils, and shells of ammunition rounds.
- Bronze
- Brass
- Both a and b
- None of these
Hint:
The large molecules made from the repeated smaller units are known as polymers. These smaller units are known as monomers. These monomers share electrons and form covalent bonds with each other to form the polymer and release water molecules or any other molecule like carbon dioxide as a byproduct.
The correct answer is: Brass
Brass is used for making electric switches of various kinds, taps, statues, household utensils, and shells of ammunition rounds.
