  1. Antoine Lavoisier

  2. John Dalton

  3. Dmitri Mendeleev

  4. Robert Boyle


Correct Option: A
Explanation:

Antoine Lavoisier is widely regarded as the father of modern chemistry due to his groundbreaking work on combustion and the law of conservation of mass.

What is the basic unit of matter?

  1. Atom

  2. Molecule

  3. Compound

  4. Element


Correct Option: A
Explanation:

An atom is the basic unit of matter and consists of a nucleus containing protons and neutrons, surrounded by electrons.

What is the periodic table?

  1. A tabular arrangement of chemical elements

  2. A classification of chemical compounds

  3. A list of chemical reactions

  4. A diagram of chemical structures


Correct Option: A
Explanation:

The periodic table is a tabular arrangement of chemical elements, organized by their atomic number, electron configuration, and recurring chemical properties.

What is the law of conservation of mass?

  1. Mass can be created or destroyed in chemical reactions.

  2. Mass can be converted from one form to another.

  3. Mass remains constant in chemical reactions.

  4. Mass increases in chemical reactions.


Correct Option: C
Explanation:

The law of conservation of mass states that the total mass of the reactants in a chemical reaction is equal to the total mass of the products.

What is the difference between an atom and a molecule?

  1. An atom is a single unit of an element, while a molecule is a combination of two or more atoms.

  2. An atom is a combination of two or more elements, while a molecule is a single unit of an element.

  3. An atom is a positively charged particle, while a molecule is a negatively charged particle.

  4. An atom is a neutral particle, while a molecule is a charged particle.


Correct Option: A
Explanation:

An atom is the basic unit of an element, consisting of a nucleus containing protons and neutrons, surrounded by electrons. A molecule is a combination of two or more atoms held together by chemical bonds.
