produced
by the
simultaneous
action

acetone,
as also by
certain
other
reactions.
In
composition
it is the same as
chloroform,
with the
substitution
of
bromine
for
chlorine.
It is

effects..
Synthesis
::
Synthesis
(n.) The art or
process
of
making
a
compound
by
putting
the
ingredients
together,
as
contrasted
with
analysis;
thus, water is made by
synthesis
from
hydrogen
and
oxygen;
hence,
specifically,
the
building
up of
complex
compounds
by
special
reactions,
whereby
their
component
radicals
are so
grouped
that the
resulting
substances
are
identical
in every
respect
with the
natural
articles
when such
occur;
thus,
artificial
alcohol,
urea,
indigo
blue,
alizarin,
etc., are made by
synthesis..
Reaction
::
Reaction
(n.) An
action
induced
by vital
resistance
to some other
action;
depression
or
exhaustion
of vital force
consequent
on
overexertion
or
overstimulation;
heightened
activity
and
overaction
succeeding
depression
or
shock.
Reaction
::
Reaction
(n.) The force which a body
subjected
to the
action
of a force from
another
body
exerts
upon the
latter
body in the
opposite
direction.
Revulsion
::
Revulsion
(n.) A
sudden
reaction;
a
sudden
and
complete
change;
--
applied
to the
feelings.

Benzamide
::
Benzamide
(n.) A
transparent
crystalline
substance,
C6H5.CO.NH2,
obtained
by the
action
of
ammonia
upon
chloride
of
benzoyl,
as also by
several
other
reactions
with
benzoyl
compounds..
Xanthoproteic
::
Xanthoproteic
(a.)
Pertaining
to, or
derived
from,
xanthoprotein;
showing
the
characters
of
xanthoprotein;
as,
xanthoproteic
acid; the
xanthoproteic
reaction
for
albumin..
Resist
::
Resist
(v. t.) To
counteract,
as a
force,
by
inertia
or
reaction..
Reaction
::

Backward
tendency
or
movement
after
revolution,
reform,
or great
progress
in any
direction..
Reaction
::
Reaction
(n.) Any
action
in
resisting
other
action
or
force;
counter
tendency;
movement
in a
contrary
direction;
reverse
action.
Abutment
::
Abutment
(n.) A fixed point or
surface
from which
resistance
or
reaction
is
obtained,
as the
cylinder
head of a steam
engine,
the
fulcrum
of a
lever,
etc..
Protamin
::
Protamin
(n.) An
amorphous
nitrogenous
substance
found in the
spermatic
fluid of
salmon.
It is
soluble
in
water,
which an
alkaline
reaction,
and
unites
with acids and
metallic
bases..
Strook
::
Strontium
(n.) A
radioactive
isotope
of
strontium
produced
by
certain
nuclear
reactions,
and
constituting
one of the
prominent
harmful
components
of
radioactive
fallout
from
nuclear
explosions;
also
called
radiostrontium.
It has a
half-life
of 28
years..
Lactucin
::
Lactucin
(n.) A
white,
crystalline
substance,
having
a
bitter
taste and a
neutral
reaction,

forming
one of the
essential
ingredients
of
lactucarium..
Test
::
Test (n.) A
reaction
employed
to
recognize
or
distinguish
any
particular
substance
or
constituent
of a
compound,
as the
production
of some
characteristic
precipitate;
also, the
reagent
employed
to
produce
such
reaction;
thus, the
ordinary
test for
sulphuric
acid is the
production
of a white
insoluble
precipitate
of
barium
sulphate
by means of some
soluble
barium
salt..
Catalysis
::
Catalysis
(n.) A
process
by which
reaction
occurs
in the
presence
of
certain
agents
which were
formerly
believed
to exert an
influence
by mere
contact.
It is now
believed
that such
reactions
are
attended
with the
formation
of an
intermediate
compound
or
compounds,
so that by
alternate
composition
and
decomposition
the agent is
apparenty
left
unchanged;
as, the
catalysis
of
making
ether from
alcohol
by means of
sulphuric
acid; or
catalysis
in the
action
of
soluble
ferments
(as
diastase,
or
ptyali
Acid
::
Acid (a.) Of or
pertaining
to an acid; as, acid
reaction..
Coagulation
::
Coagulation
(n.) The
change
from a
liquid
to a
thickened,
curdlike,
insoluble
state,
not by
evaporation,
but by some kind of
chemical
reaction;
as, the
spontaneous
coagulation
of
freshly
drawn
blood;
the
coagulation
of milk by
rennet,
or acid, and the
coagulation
of egg
albumin
by heat.
Coagulation
is
generally
the
change
of an
albuminous
body into an
insoluble
modification..
