QuestionAnswer
Chemistry The study of the composition, structure, and properties of matter, the processes that matter undergoes, and the energy changes that accompany these processes
Organic Chemistry The study of most carbon-containing compounds
Inorganic Chemistry Study of non-organic substances, many of which have organic fragments bonded to metal
Analytical Chemistry The identification of the components and composition of materials
Biochemistry The study of substances and processes occurring in living things
Theoretical Chemistry The use of mathematics and computers to understand the principals behind observed chemical behavior and to design and predict the properties of new compounds
Chemical Any substance that has a definite composition
Basic Research Carried out for the sake of increasing knowledge
Applied Research Generally carried out to solve a problem
Technological Development Typically involves the production and use of products that improve our quality of life
Volume The amount of three dimensional space an object occupies
Mass Measure of the amount of water
Matter Anything that has mass and takes up space
Atoms The smallest unit of an element that maintains the chemical identity of that element
Elements Pure substances that can't be broken down into simpler, stable substances. Each is made of atoms of two or more elements that are chemically bonded
Extensive Properties Depend on amount of matter present
Intensive Properties Do not depend on amount of matter present
Change of state Physical change of a substance from one state to another
States of matter Solid state, liquid state, gas state, plasma
Solid state Matter has a definite volume and definite shape
Liquid state Matter has definite volume but indefinite shape
Gas state Matter has neither definite volume or shape
Plasma High-temperature physical state of matter in which atoms lose most of their electrons, particles that make up atoms
Chemical Property Substance's ability to change
Chemical Change or Reaction Change when one or more substances convert into different substances
Reactants Substances that react in a chemical change
Products Substances that are formed by the chemical change
Energy .Always involved when physical or chemical changes occur .Can be in various forms (Ex: Heat, Light) .Can be absorbed or released in a change, it is not created nor destroyed .Law of conservation of energy
Mixture A blend of two or more kinds of matter, each of which retains its own identity and properties
Pure substance Has a fixed composition
