Chemistry

are
substances
that
enter
the
reaction
,
while
are
the
new
substances
formed
.
The
rate
of
a
reaction
depends
on
factors
such
as
temperature
,
concentration
,
and
.
Activation
energy
is
the
minimum
energy
required
to
start
a
reaction

A
balloon
filled
with
air
does
not
rise
as
high
as
a
balloon
filled
with
helium
gas
,
telling
me
that
helium
gas
is
dense
than
air

A
substance
is
a
single
kind
of
matter
that
has
a
specific

A

n
)
is
the
smallest

of
a
substance
.
A

is
the

unit
of
matter
that
has
the
properties
of
its

Both
a
pool
of
water
and
a
piece
of
ice
are
the
same
,
so
they
have
the
same

Characteristics
of
matter
are
called
.
Compounds
are
formed
as
a
result
of
during
chemical
reactions
in
a
set
ratio
.
Glass
breaking
,
ice
melting
,
and
the
dissolution
of
sugar
in
water
are
all
properties
.
Iron
rusting
,
silver
tarnishing
,
fruit
ripening
,
and
combustion
are
all
properties
.
Substances
in
a
keep
their
own
properties
since
they
are
not
chemically
combined
.
The

an
object
is
a
measure
of
the
thermal
energy
(
motion

The
energy
stored
in
bonds
between
atoms
is
energy
,
a
form
of

.
The
form
or
appearance
of
a
substance
is
altered
during
a
(
n
)
change
,
where
the
actual
chemical
composition
or
ratio
of
atoms
is
altered
during
a
(
n

change
.
The
Law
of
states
that
in
any
physical
or
chemical
change
,
matter
is
neither
created
or
destroyed
,
only
changed
from
one
form
to
another
.
The
mass
of
an
object
is
,
whereas
the
weight

The
mass
per
unit
volume
of
an
object
is
a
measure
of

The
simplest
type
of

The
substances
in
a
mixture
are
evenly
distributed
and
you
cannot
see
the
parts
