Questions and Answers

1.

John Dalton is best known for proposing the Atomic Theory, which states that
- A.
  
  Atoms are indivisible and indestructible.
- B.
  
  Atoms have different shapes and sizes.
- C.
  
  Atoms combine in fixed ratios.
- D.
  
  Atoms are made up of protons, neutrons, and electrons.
Correct Answer
A. Atoms are indivisible and indestructible.

Explanation
John Dalton's Atomic Theory proposed that atoms are indivisible and indestructible, forming the basis of modern chemistry by suggesting that elements consist of distinct, unbreakable particles with unique properties. While subsequent discoveries revealed atomic structure, Dalton's theory laid the foundation for understanding the fundamental nature of matter.

Dalton's Law of Partial Pressures states that
- A.
  
  The total pressure of a mixture of gases is equal to the sum of their partial pressures.
- B.
  
  The total pressure of a mixture of gases is always less than the sum of their partial pressures.
- C.
  
  The total pressure of a mixture of gases is always greater than the sum of their partial pressures.
- D.
  
  The total pressure of a mixture of gases remains constant regardless of their partial pressures.
Correct Answer
A. The total pressure of a mixture of gases is equal to the sum of their partial pressures.

Explanation
Dalton's Law of Partial Pressures states that in a mixture of non-reacting gases, the total pressure exerted is equal to the sum of the partial pressures of the individual gases.

According to Dalton's Law of Multiple Proportions
- A.
  
  Elements can combine in multiple ways to form different compounds.
- B.
  
  The mass of one element is always an integer multiple of the mass of another element in a compound.
- C.
  
  The volume of a gas is inversely proportional to its pressure.
- D.
  
  The pressure of a gas is directly proportional to its temperature.
Correct Answer
A. Elements can combine in multiple ways to form different compounds.

Explanation
Dalton's Law of Multiple Proportions states that when two elements combine to form multiple compounds, the ratio of the masses of one element that combine with a fixed mass of the other element can be expressed in small whole numbers. This implies that elements can combine in different ratios to form distinct compounds, which laid the foundation for understanding the atomic nature of matter and the concept of multiple compounds between the same elements.

Dalton's Law of Definite Composition states that
- A.
  
  Compounds are composed of atoms of different elements.
- B.
  
  All samples of a given compound have the same proportion of elements by mass.
- C.
  
  The density of a gas is directly proportional to its molar mass.
- D.
  
  Atoms combine to form molecules in simple whole-number ratios.
Correct Answer
B. All samples of a given compound have the same proportion of elements by mass.

Explanation
Dalton's Law of Definite Composition states that in a given compound, the elements are always combined in fixed and consistent mass proportions, meaning that different samples of the same compound will have the same element-to-element mass ratio. This principle contributed to the understanding of the consistent and predictable nature of chemical compounds.

John Dalton was the first scientist to explain the behavior of gases using the concept of
- A.
  
  Avogadro's Law
- B.
  
  Boyle's Law
- C.
  
  Charles's Law
- D.
  
  Dalton's Law
Correct Answer
D. Dalton's Law

Explanation
John Dalton was the first to explain the behavior of gases using his own law, Dalton's Law of Partial Pressures.

Rate this question:
6.

The law that states "The total mass of substances present at the end of a chemical reaction is the same as the mass of substances present before the reaction" is called
- A.
  
  Law of Conservation of Mass
- B.
  
  Law of Multiple Proportions
- C.
  
  Law of Definite Composition
- D.
  
  Law of Definite Proportions
Correct Answer
A. Law of Conservation of Mass

Explanation
The Law of Conservation of Mass states that in a closed system, the total mass of substances before a chemical reaction is equal to the total mass of substances after the reaction. This principle reflects the idea that atoms are neither created nor destroyed in chemical reactions; they are rearranged to form new compounds. As a result, the total mass remains constant, illustrating the fundamental principle of mass conservation in chemical processes.

Rate this question:

Dalton's Atomic Theory was proposed in which century
- A.
  
  16th
- B.
  
  17th
- C.
  
  18th
- D.
  
  19th
Correct Answer
C. 18th

Explanation
John Dalton proposed his Atomic Theory in the early 19th century, specifically around 1803.

Rate this question:
8.

According to Dalton, which of the following statements about atoms is NOT true
- A.
  
  Atoms of different elements have different masses
- B.
  
  Atoms of the same element are identical in mass and properties
- C.
  
  Atoms cannot be subdivided, created, or destroyed
- D.
  
  Atoms combine in whole-number ratios to form compounds
Correct Answer
A. Atoms of different elements have different masses

Explanation
Dalton's original atomic theory did not include the subatomic particles like protons, neutrons, and electrons. This understanding came later with the advancement of atomic research.

  Law of Definite Composition
- C.
  
  Law of Multiple Proportions
- D.
  
  Law of Conservation of Mass
Correct Answer
A. Dalton's Law of Partial Pressures

Explanation
This law states that when two elements form more than one compound, the ratios of the masses of one element that combine with a fixed mass of the other are in small whole numbers.
