Study Notes

Importance of Chemistry in Barbering

Knowledge of chemistry allows barbers to use products effectively and safely.
Chemicals are integral to daily barbering practices, including disinfection and infection control.
Understanding ingredients helps barbers select the best products for client services.
Familiarity with chemical reactions aids in preventing and resolving issues during applications.

Overview of Basic Chemistry Concepts

Organic Chemistry: Focuses on carbon-containing compounds; includes natural and synthetic materials like gasoline and plastics. Most organic substances have the ability to burn.
Inorganic Chemistry: Deals with non-carbon substances, often found in metals, minerals, water, and air. Inorganic substances cannot burn and were never alive.

Definition of Matter

Matter is defined as anything occupying space and having mass; can exist as solid, liquid, or gas.
Physical properties of matter are perceivable through touch, taste, smell, or sight.
Unlike matter, energy (light, electricity) does not have mass and cannot occupy space.

Elements and Their Classification

An element is the simplest form of chemical matter, consisting of only one type of atom; it retains its identity and cannot be broken down further.
There are 118 known elements, with 98 occurring naturally and 20 being synthetic or artificially produced.
