Chemistry MCQ Quiz

Chemistry Basics

• The study of matter and its interactions is referred to as chemistry.
• Chemistry encompasses the investigation of the properties, composition, and behavior of substances.

Chemical Reactions

• Chemical reactions involve the transformation of reactants into products.
• This transformation is a fundamental aspect of chemical processes, resulting in new substances with different properties.

Atomic Structure

• The identity of an element is determined by the number of protons in its nucleus, also known as the atomic number.
• The atomic number is unique to each element and defines its position in the periodic table.

Periodic Table Organization

• Elements in the periodic table are arranged by increasing atomic number.
• The periodic table reflects the regular periodicity in the properties of elements based on their atomic structure.

Solutions and Cell Interaction

• A solution where the solute concentration is lower than that of the cell is termed hypotonic.
• Hypotonic solutions cause cells to swell as water enters them, owing to osmosis.
