Arun Sharma answered |
Amphoteric metal oxides react with both acids as well as bases to produce salt and water.
Aluminium oxide is an amphoteric oxide because it reacts with acids as well as bases and form salts and water.
Al2O3 + 6HCl → 2AlCl3 + 3H2O (Basic nature)
Aluminium Hydrochloric Aluminium Water
oxide acid chloride
Al2O3 + 2NaOH → 2NaAlO2 + H2O (Acidic nature)
Aluminium Sodium Sodium Water
oxide Hydroxide aluminate

- b)Presence of free electrons
- c)Its high polishing
- d)Its chemical inertness
Correct answer is option 'B'. Can you explain this answer?
The lustre of a metal is due to:
a)
Its high density
b)
Presence of free electrons
c)
Its high polishing
d)
Its chemical inertness
|
Rohini Seth answered |
The lustre of a metal is due to presence of free electrons.
It has to do with the way light and electrons on the surface of metals interact. The outer electrons in a metal are almost not bound to any individual atom, thus are relatively free, and are concentrated on the surface. These electrons (electron density) tend to oscillate at a collective frequency.

Which allotrope of carbon conducts electricity?
a)
Graphite
b)
Diamond
c)
Fullerene
d)
Both Graphite and Diamond

Most Abundant Non-Metal on Earth:
Explanation:
Oxygen is the most abundant non-metal on Earth. It makes up around 21% of the Earth's atmosphere, and it is also found in the Earth's crust, oceans, and other compounds like water and rocks. Oxygen is essential for life as it is a key component of the air we breathe and is necessary for the respiration of living organisms.
Other Options:
Let's take a look at the other options and why they are not the most abundant non-metal on Earth:
a) Sulphur - Sulphur is a non-metal, but it is not the most abundant on Earth. Although it is found in large quantities in the Earth's crust and oceans, it is not as abundant as oxygen.
c) Silicon - Silicon is a non-metal that is found in the Earth's crust, but it is not as abundant as oxygen. It is often found in rocks and minerals like quartz and sand, but it is not as essential to life as oxygen.
d) Phosphorus - Phosphorus is a non-metal that is found in the Earth's crust, but it is not as abundant as oxygen. It is often used in fertilizers and is an important component of DNA, but it is not as essential to life as oxygen.
Conclusion:
In conclusion, oxygen is the most abundant non-metal on Earth. It is essential for life and is found in the Earth's atmosphere, crust, oceans, and other compounds.

EduRev UPSC answered |
(d) (i) and (iv)
Explanation: Aluminum is ductile and has a high electrical conductivity, which makes it unsuitable for utensil production. Aluminium has a high melting point and good heat conductivity. Copper, steel (an alloy of iron), and aluminium are the most popular metals used to make utensils. Due to their ability to conduct heat, copper and aluminium are the most used materials.
