Match the following (a) a non-metal that exists in two forms (i) Chlorine (b) a non-metal which is liquid at room temperature (ii) Zinc (c) a metal which is constituent of brass and bronze (iii) Carbon (d) a non-metal used for disinfecting water (iv) Bromine (e) a metal used in electroplating (v) Copper Correct Answer (a) - (iii), (b) - (iv), (c) - (v), (d) - (i), (e) - (ii)
Explanation:
Chlorine:
- Chlorine is the non-metal that possesses the quality of killing germs present in the water. Hence, it is used for disinfecting water.
Zinc:
- Zinc is the metal commonly used in electroplating.
- Electroplating is the process of metal coating on another piece of metal through an electrodeposition process.
Carbon:
- Carbon is non-metal that exists in 2 forms and shows allotropism.
- Allotropism is the property of some chemical elements in which the element exists in two different forms in the same physical states and those forms are the allotropes of elements.
- Diamond and graphite are 2 allotropes of carbon.
Bromine:
- Bromine is the only non-metal that is liquid at room temperature.
- It is a thick, reddish-brown liquid that evaporates to an orange vapor at standard temperature & pressure.
- While sulfur and carbon are the non-metals which is solid at room temperature.
Copper:
- Copper is a metal.
- Brass & bronze are copper-based alloys.
- Brass is a metal alloy that is made up of copper and zinc.
- Bronze is a metal alloy that is made up of copper and tin.
- Alloy is a substance that combines more than one metal or mixes metal with other non-metallic elements.
Therefore, the correct answer is (a) - (iii), (b) - (iv), (c) - (v), (d) - (i), (e) - (ii).
