Which of the following is not an characteristics of metal?

• Malleability

• High conductivity

• Ductile

• None of them

1 kg of iron occupies LESS SPACE compared to 1 kg of sponge. Why

• Iron has less density than sponge

• Iron and sponge have equal density

• Iron has more density than sponge

• none of them

Answer explanation

Density = mass/volume

=> Volume (Space) = Mass/density

Iron has higher density than sponge.

With the same of mass (1kg)

=> Sponge has more space than iron

Which of the following elements produce basic oxides upon reacting with oxygen?

• Chlorine

• Sulfur

• Sodium

• Hydrogen

Answer explanation

Metal reacts with oxygen to form basic oxide.

Zinc granules give H₂ gas when treated with dilute solution of:

• FeO

• HCl

• NaCl

• All of them

Answer explanation

Metal reacts with acid to form salt and hydrogen.

It's a displayed hydrogen reaction.

Zn + 2HCl => ZnCl2 + H2

Give name of a metal is so soft which can be cut with a knife:

• Iron

• Copper

• Calcium

• Sodium

Answer explanation

Sodium is silver white color metal with malleable and ductile property. It is the metal that can easily be cut with a knife.

Most of metals which occur in their native state in nature:

• are very reactive

• do not form any compound

• are not reactive

• are moderately reactive
