What Do You Know About Chemistry? - Quiz

Chemistry is a branch of science showing the interaction and relationship between two elements of compounds. Let’s find out what you know about chemistry with the short quiz.

Questions and Answers

1.

What kind of science is chemistry?
- A.
  
  Spiritual
- B.
  
  Psychological
- C.
  
  Physical
- D.
  
  Historical
Correct Answer
C. pHysical

Explanation
Chemistry is a physical science because it deals with the study of matter and its properties, as well as the changes it undergoes during chemical reactions. It involves the understanding of the composition, structure, and behavior of substances at the atomic and molecular level. Chemistry relies on principles and theories from physics to explain the behavior of atoms and molecules, making it a branch of physical science.

In Chemistry, what is majorly dealt with?
- A.
  
  Arts and culture
- B.
  
  Biological materials
- C.
  
  Chemical and Matter
- D.
  
  Spirit and mind
Correct Answer
C. Chemical and Matter

Explanation
Chemistry is a branch of science that primarily deals with the study of chemicals and matter. It focuses on the composition, properties, structure, and reactions of substances. This includes understanding the behavior of atoms, molecules, and ions, as well as their interactions and transformations. Therefore, the correct answer is "Chemical and Matter."

3.

Which of these is not a type of chemical reaction?
- A.
  
  Decomposition Reaction
- B.
  
  Acid Base reaction
- C.
  
  Combustion Reaction
- D.
  
  Degeneration Reaction
Correct Answer
D. Degeneration Reaction

Explanation
Degeneration reaction is not a type of chemical reaction. Decomposition reaction involves the breakdown of a compound into simpler substances, acid-base reaction involves the transfer of protons between acids and bases, and combustion reaction involves the rapid combination of a fuel with oxygen to produce heat and light. However, degeneration reaction is not a recognized type of chemical reaction.

What is formed when two are more chemical elements are chemically bond together?
- A.
  
  Space
- B.
  
  Environment
- C.
  
  Vacuum
- D.
  
  Compound
Correct Answer
D. Compound

Explanation
When two or more chemical elements are chemically bonded together, a compound is formed. A compound is a substance that consists of two or more different elements chemically combined in a fixed ratio. The elements in a compound are held together by chemical bonds, which can be either ionic or covalent. Compounds have unique properties that are different from the properties of their individual elements.

In chemistry, what can never be broken down into simpler forms either by physical or chemical means?
- A.
  
  Atom
- B.
  
  Protons
- C.
  
  Gases
- D.
  
  Elements
Correct Answer
D. Elements

Explanation
Elements are substances that cannot be broken down into simpler forms by physical or chemical means. They are the fundamental building blocks of matter and are composed of only one type of atom. Each element has its own unique set of properties and characteristics, which distinguish it from other elements. Elements are the basic components of all matter and are represented by symbols in the periodic table.

What is the simplest and smallest form of a matter ?
- A.
  
  Atom
- B.
  
  Molecules
- C.
  
  Element
- D.
  
  Compound
Correct Answer
A. Atom

Explanation
An atom is the simplest and smallest form of matter because it is the basic unit of a chemical element. Atoms are made up of protons, neutrons, and electrons. They cannot be broken down further without losing their unique properties. Molecules, elements, and compounds are composed of multiple atoms bonded together in different ways, making them more complex and larger in size compared to individual atoms.

7.

One of these is not a branch of chemistry?
- A.
  
  Organic chemistry
- B.
  
  Inorganic chemistry
- C.
  
  Analytic chemistry
- D.
  
  Quantitative chemistry
Correct Answer
D. Quantitative chemistry

Explanation
Quantitative chemistry is not a branch of chemistry. It is a sub-discipline within analytical chemistry that focuses on the measurement and quantification of chemical substances and their properties. It involves the use of mathematical and statistical methods to analyze and interpret experimental data. In contrast, organic chemistry, inorganic chemistry, and analytical chemistry are all recognized branches of chemistry that study different aspects of chemical compounds and reactions.

8.

How many elements are in the periodic table?
- A.
  
  180
- B.
  
  134
- C.
  
  118
- D.
  
  140
Correct Answer
C. 118

Explanation
The periodic table consists of all the known chemical elements, arranged in order of their atomic numbers. As of now, there are 118 confirmed elements in the periodic table. Each element is represented by a unique symbol and has its own distinct properties.

In Chemistry, Oxygen is used for the following except:
- A.
  
  Oxidizing
- B.
  
  Combustion
- C.
  
  Reduction
- D.
  
  Metal Cutting
Correct Answer
C. Reduction

Explanation
Oxygen is commonly used for oxidizing, combustion, and metal cutting processes. However, it is not used for reduction reactions. Reduction involves the gain of electrons or a decrease in the oxidation state of a substance, while oxygen is typically involved in oxidation reactions where it loses electrons or increases its oxidation state. Therefore, oxygen is not used for reduction.

Where does the word “chemistry” comes from?
- A.
  
  Chemplast
- B.
  
  Alichem
- C.
  
  Chemcast
- D.
  
  Alchemy
Correct Answer
D. Alchemy

Explanation
The word "chemistry" comes from the term "alchemy." Alchemy was a medieval practice that aimed to transform base metals into gold and discover a universal panacea. It also involved the study of various substances and their properties. Over time, alchemy evolved into modern chemistry, which focuses on the composition, structure, properties, and reactions of substances. Hence, the word "chemistry" is derived from its predecessor, alchemy.
