Science vocabulary
Exploring Creation w/ Chemistry - vocabulary (L - N)
| Term | Definition |
|---|---|
| Le Chatelier's Principle | When stress (such as change in concentration, pressure, or temperature) is applied to an equilibrium, the reaction will shift in a way that relieves the stress and restores the equilibrium |
| Lead-acid battery | A battery that runs on the oxidation of lead and the reduction of lead oxide in the presence of sulfuric acid |
| Lewis structure | A schematic representation of the valence of electrons in an atom or molecule |
| Limiting reactant | The reactant that runs out first in a chemical reaction. It determines the amount of products made. |
| Liter | A metric unit of volume |
| Mass | A measure of the amount of matter in an object |
| Mass number | The total number of neutrons and protons in an atom |
| Matter | Anything that has mass and takes up space |
| Melting | The process by which a substance changes from its solid phase to its liquid phase |
| Melting point | The temperature a which a substance changes from its solid phase to its liquid phase |
| Meniscus | The curved surface of a liquid, typically in a glass container |
| Metal | An element that tends to give up its electrons |
| Meter | The metric unit of length |
| Mixture | A substance that contains different compounds and/or elements |
| Model | A constructed image of something we cannot see with our eyes |
| Molality (m) | The number of moles in a solute per kilogram of solvent |
| Molar mass | The mass of one mole of a given compound |
| Molarity (M) | A concentration unit that tells how many moles of a substance are in a liter of solution (It is determined by taking the number of moles in a substance and dividing by the number of liter of solution) |
| Mole | A group of atoms or molecules that number 6.02×〖10〗^23 |
| Mole fraction | The number of moles of a given component in a mixture divided by the total number of moles in the mixture |
| Molecular formula | A chemical formula that provides the number of each type of atom in a molecule |
| Molecular mass | The mass of a single molecule |
| Molecule | More than one atom bound together to form a compound |
| Neutralization reaction | A reaction between an acid and base that neutralizes both, typically forming salt and water |
| Neutron | One of the three particles that make up and atom (it is electrically neutral) |
| Newton | The metric unit of force |
| Nonmetal | An element that tends to take electrons from other elements |
| Nucleus | The center of the atom that contains the neutrons and protons |
