Welcome to Chemistry Study Hub
This website is designed as a focused study companion for chemistry students. It brings together foundational laws, molecular structure examples, useful formulas, and short quizzes in one accessible place. The goal is to help learners review key concepts, strengthen understanding, and build better study habits.
Chemistry Laws
Boyle's Law
Pressure and volume are inversely proportional when temperature remains constant.
Charles's Law
Volume increases as temperature increases when pressure remains constant.
Avogadro's Law
Equal volumes of gases at the same temperature and pressure contain equal numbers of molecules.
Molecular Diagrams
Water (H₂O)
Bent molecular geometry with oxygen bonded to two hydrogen atoms.
Carbon Dioxide (CO₂)
Linear structure with carbon double-bonded to two oxygen atoms.
Methane (CH₄)
Tetrahedral geometry with carbon at the center.
Important Formulas
Density: d = m / V
Molarity: M = mol / L
Ideal Gas Law: PV = nRT
