chemistry metals chemical properties and uses of metals and non-metals introduction to metals physical properties of non-metals

  1. Fine duct of aluminium - Paints and Lacquers

  2. Reducing agent in the manufacture of dye-stuffs, paints, etc. - copper dust

  3. For cutting tools and crushing machines - Chrome steel

  4. For making cables, automobiles and aeroplane parts - Nickel steel

Show answer
Correct Option: B
Explanation:

The fine duct of aluminium is used in paints and lacquers. For cutting tools and crushing machines chrome steel is used.

For making cables, automobiles and aeroplane part – nickel steel is used. But copper dust is not used as a reducing agent in the manufacture of dyestuffs and paints. So this second is the mismatch.

Correct option is B.

Iron is used in construction of bridges and houses.

chemistry metals chemical properties and uses of metals and non-metals introduction to metals physical properties of non-metals

  1. True

  2. False

Show answer
Correct Option: A
Explanation:

There are many different types of steels available today. Each type is made with iron combined with different elements including carbon, silicon, and nickel among others. Steel is an important component in every structure, in every type of construction. Therefore Buildings, bridges, skyscrapers, and other types of construction would not be complete if it does not include iron in its framework.

________ is called a space age metal and used in military jets and spacecrafts.

chemistry metals chemical properties and uses of metals and non-metals introduction to metals physical properties of non-metals

  1. Zinc

  2. Platinum

  3. Copper

  4. Titanium

Show answer
Correct Option: D
Explanation:

TItanium is known as the space age metal and  is expected to replace most of the metals used around the industries. However, its expensive and difficult mining process is keeping it from being used so commonly as aluminium or steel. Titanium is found to be stronger, durable and corrosion resistive in comparison to steel. It has the highest strength to weight ratio of all the metals. All these properties, along with its light weight, make it an ideal metal for space crafts and military jets. It is also used in making highly water - resistant diving watches.
