General chemistry is the foundational branch of science that explores the fundamental principles governing matter and its interactions. It covers essential topics such as atomic structure, where atoms are described as the building blocks of elements; chemical bonding, which explains how atoms combine to form molecules through forces like ionic, covalent, and metallic bonds; and stoichiometry, the quantitative study of reactants and products in chemical reactions.
The field also delves into states of matter—solids, liquids, gases, and plasmas—and their properties, as well as thermodynamics, which examines energy changes in reactions, including concepts like enthalpy, entropy, and Gibbs free energy. Kinetics addresses the rates and mechanisms of reactions, while equilibrium explores systems where forward and reverse reactions occur at equal rates.
Additionally, general chemistry introduces solutions and their concentrations, acids and bases with their pH scales, and electrochemistry, which involves the study of electricity and chemical reactions. This discipline serves as a gateway to more specialized areas like organic, inorganic, and physical chemistry, fostering critical thinking and problem-solving skills essential for scientific inquiry and everyday applications, from medicine to environmental science.

Options:
A. 1:1
B. 2:1
C. 1:2
D. 4:1
Answer: B
Explanation: The balanced equation shows 2 moles of H₂ react with 1 mole of O₂, giving a ratio of 2:1.
5. Question: What is the pH of a neutral solution?
Options:
A. Less than 7
B. Greater than 7
C. Exactly 7
D. Between 0 and 14
Answer: C
Explanation: A neutral solution has a pH of 7, which occurs when the concentration of hydrogen ions equals the concentration of hydroxide ions.
6. Question: Which gas law states that the volume of a gas is inversely proportional to its pressure at constant temperature?
Options:
A. Charles’s law
B. Boyle’s law
C. Gay-Lussac’s law
D. Avogadro’s law
Answer: B

7. Question: What is the electron configuration of carbon?
Options:
A. 1s² 2s² 2p⁶
B. 1s² 2s² 2p⁴
C. 1s² 2s² 2p²
D. 1s² 2s¹ 2p³
Answer: C
Explanation: Carbon has an atomic number of 6, so its electron configuration is 1s² 2s² 2p², with two electrons in the 2p subshell.
