MODULE 1: FUNDAMENTALS OF INORG CHEM Flashcards
the SCIENCE THAT DESCRIBES MATTER
CHEMISTRY
THE CENTRAL SCIENCE
CHEMISTRY
hydrocarbons & its derivatives
ORGANIC CHEMISTRY
inorganic compounds, metals, minerals
INORGANIC CHEMISTRY
DETECTION AND IDENTIFICATION of substances present (qualitative analysis) o amount of each substance (quantitative analysis)
ANALYTICAL CHEMISTRY / MEASUREMENT SCIENCE
processes in living organisms
BIOCHEMISTRY
behavior of matter
PHYSICAL CHEMISTRY
anything that HAS MASS AND OCCUPIES SPACE
MATTER
measure of the QUANTITY OF MATTER
MASS
AMOUNT OF SPACE
VOLUME
the CAPACITY TO DO WORK or TO TRANSFER HEAT
ENERGY
not considered as matter but considered as energy
light, sound, electricity & heat
energy in MOTION
KINETIC ENERGY
energy AT REST
POTENTIAL ENERGY
release heat
EXOTHERMIC
absorbs heat
ENDOTHERMIC
- molecules PACKED CLOSE TOGETHER ORDERLY
- rigid
SOLID
- molecules are CLOSE BUT RANDOMLY ARRANGED
- FLOWS and assumes shape of container
LIQUID
- molecules are FAR APART
- fills any container completely
- highly compressible
- expands indefinitely
GAS
solid to gas
SUBLIMATION
gas to solid
DEPOSITION
gas to liquid
CONDENSATION
liquid to gas
BOILING
liquid to solid
FREEZING
solid to liquid
MELTING
- CAN BE OBSERVED OR MEASURED without changing the identity of the substance
PHYSICAL PROPERTIES
- exhibited by matter as it UNDERGOES CHANGES in composition
CHEMICAL PROPERTIES
dependent on the amount of substance
EXTENSIVE PROPERTIES
- INDEPENDENT on the amount of substance
INTENSIVE PROPERTIES
- ONE OR MORE SUBSTANCES are used up
- one or more new substances are formed,
- energy is absorbed or released
- IRREVERSIBLE
CHEMICAL CHANGE
- NO CHANGE in chemical composition
- REVERSIBLE
PHYSICAL CHANGE
- variable composition
- MAY BE SEPARATED into pure substances by physical methods
MIXTURE
- FIXED COMPOSITION
- CANNOT BE SEPARATED into simpler substances by physical methods
PURE SUBSTANCE
