Question
Answer
What is the difference
between a physical change
and a chemical change?
A physical change affects the form of a substance but
not its chemical composition, such as melting or
freezing. A chemical change results in the formation of
one or more new substances with different properties,
such as rusting or combustion.
How can you distinguish
between a mixture and a
pure substance?
A mixture consists of two or more substances physically
combined and can be separated by physical means,
while a pure substance has a fixed composition and
cannot be separated into other substances by physical
methods.
What are the main states of
matter, and how do they
differ?
The main states of matter are solid, liquid, gas, and
plasma. Solids have a fixed shape and volume, liquids
have a fixed volume but take the shape of their
container, gases have neither fixed shape nor volume,
and plasma is an ionized gas with unique electrical
properties.
How does conservation of
mass apply to chemical
reactions?
The law of conservation of mass states that mass is
neither created nor destroyed in a chemical reaction.
The total mass of reactants equals the total mass of
products.
What is an example of a
chemical property?
An example of a chemical property is flammability,
which is a substance's ability to burn in the presence of
oxygen.
How can you separate the
components of a
heterogeneous mixture?
Components of a heterogeneous mixture can be
separated by physical methods such as filtration,
decanting, or using a magnet depending on the
properties of the components.
What is the significance of
the periodic table in
understanding matter and
change?
The periodic table organizes elements based on their
atomic number and properties, helping predict element
behavior, reactivity, and types of chemical changes they
undergo.
What distinguishes an
element from a compound?
An element is a pure substance consisting of only one
type of atom, while a compound consists of two or more
different atoms chemically bonded together.
Why are changes in state
considered physical changes?
Changes in state involve changes in physical form (solid,
liquid, gas) without altering the chemical composition of
the substance, making them physical changes.
How do endothermic and
exothermic reactions differ in
terms of energy change?
Endothermic reactions absorb energy from the
surroundings, usually as heat, while exothermic
reactions release energy to the surroundings.
