Study Notes

Introduction to Chemistry

Chemistry is defined as the study of matter, exploring its properties, composition, structure, and changes.
Matter is anything that has mass and occupies space, which includes solids, liquids, gases, and plasma.

Branches of Chemistry

Major branches include organic chemistry (study of carbon-containing compounds), inorganic chemistry (study of inorganic compounds), and physical chemistry (study of the properties and changes of matter).
Analytical chemistry focuses on determining the composition of substances, while biochemistry examines the chemical processes within living organisms.

Importance of Chemistry

Chemistry is fundamental in various fields such as medicine, engineering, environmental science, and nutrition.
It aids in the development of pharmaceuticals, materials science, and sustainable energy solutions.

Key Concepts in Chemistry

Atoms are the basic units of matter, consisting of protons, neutrons, and electrons.
Elements are pure substances that cannot be broken down further and are organized in the periodic table.
Compounds are substances made of two or more different elements that are chemically bonded.

Chemical Reactions

Chemical reactions involve the transformation of reactants into products, governed by conservation of mass.
Types of reactions include synthesis, decomposition, single replacement, and double replacement.

Measurement and Units

Chemistry employs a variety of measurements, including mass (grams), volume (liters), and concentration (molarity).
The metric system is predominantly used for precision and consistency in scientific measurements.
