- Meniscus
- The shape assumed by the surface of a liquid in a cylindrical container.
- Stoichiometry
- The calculation of the quantities of chemical elements or compounds involved in chemical reactions.
- Pressure
- The exertion of force upon a surface by an object, fluid, etc.
- Radiation
- High energy particles or rays emitted during the nuclear decay process
- Accuracy
- How closely a measured value agrees with the correct value.
- Exothermic
- Describes process that release heat energy.
- Compound
- A substance of two or more elements in fixed proportions.
- Polarity
- The positive or negative state in which a body reactsw to a magnetic, electric, or other field.
- Thermal Energy
- Energy used in the form of heat.
- Decomposition
- A reaction in which a compound is broken down into a simpler compound or element. Compounds sometimes decompose if heated strongly or if subjected to a stron electric current.
- Centrifuging
- An apparatus that rotates at high speed and by centrifugal force separates substances of different densities, as amild and cream.
- Lone Pairs
- Pair of electrons residing on one atom and not shared by other atoms; unshared pair.
- VSEPR
- Valence Shell Electron Pair Repulsion
- Electromagnetic
- Pertaining to or exhibiting magnetism produced by electric charge in motion
- Prism
- A transparent solid body, often having triangular bases, used for dipersing light into a spectrum or for reflecting rays of light.
- Precision
- Mechanical or scientific exactness
- Base
- A substance the produces OH (aq) ions in aqueous solution. Stron soluble bases are soluble in water and are completely dissociated. Weak base ionize only slightly.
- Unsaturated
- Having a double or triple bond and capable of talking on elements or groups by direct chemical combination without the liberation of other elements or compounds
- Mechanical Energy
- Energy in a mechanical form.
- Emission
- A measure of the number of electrons emitted by the heated filament or cathode of a vaccum tube.
- Protons
- A subatomic particle having a mass of 1.0073 amu and a charge of +1, found in the nuclei or atoms
- Metal-Metal
- Metalic compound
- Volatile
- A solid or liquid material that easily vaporizes. A material with a significant vapor pressure.
- Gravitational Energy
- Energy used in gravity.
- Wavelength
- Length of a wave. From crest to crest.
- Subscript
- Any character, number, or symbol written next to and slightly below another.
- Condensation
- Liquefication of vapor.
- Endothermic
- Describes the process that absorbs heat energy.
- Single Bond
- Covalent bond resulting from the sharing of two electrons (one pair) between two atoms
