Chemistry of Metals and Alloys Questions

Multiple choice physics semiconductors integrated circuits & microprocessor integrated chips semiconductor devices

Which of the following is used for the fabrication of Integrated circuits?

  1. Semiconductors

  2. Metals

  3. Insulators

  4. Alloys.
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

An integrated circuit is an electronic circuit formed on a small piece of semiconducting material, which performs the same function as a larger circuit made from discrete components. A semiconductor such as silicon can be controlled to conduct much or little. This allows making transistors that control each other.

Multiple choice chemistry pure substances and mixtures: separation of mixtures mixtures: examples and properties types of solutions all about mixtures

Among the following, bronze is a/an example of :

  1. an element

  2. a mixture

  3. a compounds

  4. all of these
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Bronze is a alloy, it is composed of the mixture of copper and tin. It was made before 3000 bc, though its use in artifacts did not become common until much later. The proportions of copper and tin varied widely (from 67 to 95 percent copper in surviving artifacts).

Multiple choice reactions of haloarenes haloalkanes and haloarenes chemistry

Which of the following reaction involves copper metal?

  1. Wurtz reaction

  2. Wurtz-Fittig reaction

  3. Ullmann reaction

  4. Frankland reaction

Option C is correct.

Multiple choice chemistry d and f block elements solid solutions formation of complex compounds and constituent of catalysts general characteristics of first transition series

Stainless steel contains:

  1. Cu and Zn

  2. Cu and Sn

  3. Pb and Sn

  4. Fe, C, Cr and Ni
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Stainless steel is a metal alloy made up of steel mixed with elements such as chromium, nickel, molybdenum, silicon, aluminium, and carbon. 


Iron mixed with carbon to produce steel is the main component of stainless steel. Chromium is added to make it resistant to rust.

Multiple choice chemistry d and f block elements solid solutions formation of complex compounds and constituent of catalysts general characteristics of first transition series

Which of the following set of metals can form alloy.

  1. $Cu$ and $Au$
  2. $Li$ and $Na$
  3. $Fe$ and $Hg$

  4. All of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Metals combined with other substances to make them stronger, harder, lighter, or better in some other way. An alloy like this will form only if the atoms of the base metal and those of the alloying agent are of roughly similar size. In most substitution alloys, the constituent elements are quite near one another in the periodic table. 

Corinthian bronze, is an alloy of copper with gold or silver.
Almost all metals can form amalgams with mercury, the notable exceptions being iron, platinum, tungsten, and tantalum.
