Give reason (1) Sodium is stored under kerosen. (2) copper is used as connecting wires (3) Phosphorus is stored in water
Answers
Explanation:
sodium is stored under kerosene because it is higly reactive.
copper is used in wires as its is ductile and a good conductor of electricity
phosphorus also reacts with air like sodim therefore its kept in water.
Explanation:
1) Sodium is highly reactive element it reacts with atmospheric oxygen when kept open so it is stored under kerosene so that it will not be able to come in contact with oxygen
2)Copper is an excellent conductor of electricity; no other metal can compete with it in terms of electrical conductivity. The wires made of this reddish metal are capable of carrying comparatively more electric current per diameter of wire.
3)White phosphorus is highly reactive, and spontaneously ignites at about 30°C in moist air. It is usually stored under water, to prevent exposure to the air.
