Question 1
1 / -0

Zirconium is used in:

A
poison ivy lotion

B
sand papers

C
ceramics

D
all of above

Solution

Zirconium $$(Zr)$$ slightly resembles Titanium $$(Ti)$$ in poison case. it is also used as a poison. It is used in making sandpaper and ceramics.
Zirconium is the main element in cubic zirconia, which has the formula $$ZrO_2$$. Also, zirconium carbonate $$(ZrCO_3)$$ binds to urushiol, the active ingredient in poison ivy oil.
Question 2
1 / -0

A manufacturer has to produce wires made of different varieties of metals. Which among the following metal cannot be taken into consideration for this purpose?

A
Gold

B
Silver

C
Aluminium

D
Zinc

Solution

Zinc is an exception among metals and does not show ductility and low thermal and electrical conductivity.
Question 3
1 / -0

Which of the following statements are correct?

A
All metals are ductile

B
All non metals are ductile

C
Generally metals are ductile

D
Some metals are ductile

Solution

The property by the virtue of which metals can be drawn into thin wires is called ductility. Generally, metals are ductile. For example, copper.
Non-metals are non-ductile as they cannot be drawn into wires.
Question 4
1 / -0

Apart from most metals, which of these materials can show ductility?

A
Plastics

B
Alloys

C
Chewing gums

D
All of these

Solution

Some plastics and some alloys have the property of getting drawn into wires. Chewing gum is also very flexible and shows ductility.
Question 5
1 / -0

Aluminium foil used for wrapping____

A
food

B
clothes

C
plastic

D
wires

Solution

Aluminum is a metal. Metals are malleable and ductile, and they can be drawn into thin sheets, and wires respectively. As aluminum is malleable, thin foil can be made out of it. These foils have the property to keep the food warm. Hence, it is used for wrapping food.
Question 6
1 / -0

Electric wires, coils, and machines are made of metals. Which of the following metal cannot be used for them?

A
copper

B
silver

C
iron

D
sodium

Solution

Electric wires, coils and machines are made of hard metals. Sodium is a very soft metal which can be cut through knife hence it cannot use to prepare electric wires, coils and machines.
Question 7
1 / -0

Which is the correct statement regarding malleability?

A
Malleability is the physical property of non-metals

B
Malleability is the chemical property of metals

C
Malleability is the physical property of metals

D
Malleability is the chemical property of non-metals

Solution

Malleability is a physical property of metals. A malleable material can be flattened into thin sheets by hammering or rolling. Solid metal can bend or be hammered into other shapes without breaking.

Hence, the correct option is $$C$$
Question 8
1 / -0

Select the objects from the following which have a characteristic shine known as lustre _____________.

A
wooden bowls.

B
towel and toys.

C
shirts and scarfs.

D
brass utensils.

Solution

Brass utensils are made up of metals. We know that metals have a characteristic shine known as lustre. Rest all the other objects mentioned are made from non-metals hence don't have lustre.
Question 9
1 / -0

The density of non metals is _____ when compared with metals.

A
high

B
same

C
low

D
none of the above

Solution

The density of non-metals is low when compared with metals as metals are solids and non-metals are liquids and gases (Generally solids are more denser than liquids and gases).
Hence, option C is correct.
Question 10
1 / -0

Nature of oxides of non-metal is :

A
Acidic

B
Basic

C
Amphoteric

D
Neutral

Solution

The oxides of non-metal are acidic in nature as oxide of non-metal reacts with water to form acid.

Example : $$CO_2 + H_2O \rightarrow H_2CO_3$$
