Already Graded A+
What is chemistry? - 🧠 ANSWER ✔✔Chemistry is the study of the
composition, structure, and properties and the changes that it undergoes.
the study of most carbon-containing compounds - 🧠 ANSWER ✔✔organic
chemistry
the study of all substances not classified as organic, mainly compounds
that do not contain carbon - 🧠 ANSWER ✔✔inorganic chemistry
the study of the property and changes of matter and their relation to energy
- 🧠 ANSWER ✔✔physical chemistry
,the identification of the components and composition of materials - 🧠
ANSWER ✔✔Analytical Chemistry
the study of substances and processes occurring in living things - 🧠
ANSWER ✔✔Biochemistry
the use of mathematics and computers to understand the principles behind
observed chemical behavior and to design and predict the properties of
new compounds - 🧠 ANSWER ✔✔Theoretical Chemistry
Any substance that has a definite composition - 🧠 ANSWER ✔✔chemical
A measure of the amount of matter - 🧠 ANSWER ✔✔mass
Anything that has mass and takes up space - 🧠 ANSWER ✔✔matter
the smallest unit of an element that maintains the properties of that
element. - 🧠 ANSWER ✔✔atom
a pure substance made of only one kind of atom - 🧠 ANSWER ✔✔element
a substance that is made from the atoms of two or more elements that are
chemically bonded - 🧠 ANSWER ✔✔compound
, Contrast extensive and intensive properties and give examples of each. - 🧠
ANSWER ✔✔Extensive properties depend on the amount of matter that is
present. Ex: volume, mass, amount of energy. Intensive properties do not
depend on the amount of matter present. Ex: melting point, boiling point,
density, ability to conduct electricity and heat
Define and distinguish between physical properties and chemical
properties. - 🧠 ANSWER ✔✔A physical property is a characteristic that can
be observed or measured without changing the identity of the substance.
Ex: melting and boiling point. A chemical property relates to a substance's
ability to undergo changes that transform it into a different substance. Ex:
iron rusting, charcoal burning, silver tarnishing
Define a change of state. - 🧠 ANSWER ✔✔An important class of physical
changes are changes of state.
What are the states of matter? - 🧠 ANSWER ✔✔Solid, liquid, gas, & plasma
solid to liquid - 🧠 ANSWER ✔✔melting
liquid to gas - 🧠 ANSWER ✔✔boiling
gas to liquid - 🧠 ANSWER ✔✔condensation
