Study Notes
Basics of Chemistry
- A mixture is made up of substances combined physically, not chemically.
- A physical change occurs when ice melts into water, demonstrating a change in state without altering chemical composition.
- Products with a pH above 7 are classified as alkaline; for instance, a product with a pH of 8.9 is alkaline.
- Silicone oils are utilized in nail polish dryers and as skin protectants.
- Approximately 90 naturally occurring elements exist, each possessing unique physical and chemical properties.
- Neutral substances, such as pure water, have a pH of 7.
- Ionization refers to the process of breaking down a substance into ions.
- Ethyl alcohol is produced through fermentation, converting grape sugars into alcohol.
- Miscible liquids mix easily with each other.
- A solvent is the liquid component in a solution responsible for dissolving other substances.
- Atoms combine chemically to form a molecule.
- A physical change results in altered properties without creating a new substance.
- The tail of a surfactant is lipophilic, meaning it has an affinity for oils.
- A solution is formed when solid, liquid, or gas substances are dissolved in a solvent.
- Alkanolamines are used in hair products to neutralize acids or adjust pH levels.
- An emulsion is a stable mixture of two or more substances using a binder.
- Suspensions are temporary mixtures where two kinds of matter are combined.
- Organic chemistry focuses on substances that contain carbon.
- Surfactants allow oil and water to mix by acting as a bridge.
- A compound forms when two or more elements combine chemically.
- Inorganic chemistry examines substances that do not contain carbon.
- Matter encompasses anything with mass that occupies space and can exist as a solid, liquid, or gas.
- The atom is the smallest unit of an element.
- Elements cannot be broken down into simpler substances.
- A compound is the new product arising from the union of multiple elements.
- Volatile organic compounds swiftly evaporate and contain carbon.
- A molecule is created through the chemical bonding of two or more atoms.
- Another term for alkalis is bases.
- A substance is considered oxidized when it reacts with oxygen.
- A reduction reaction involves the addition of hydrogen or the removal of oxygen from a substance.
- Redox is shorthand for oxidation-reduction reactions.
- A reducing agent supplies hydrogen to or removes oxygen from a chemical compound.
- The head of a surfactant molecule is hydrophilic, indicating a preference for water.
