The law of
conservation
of
mass
states that the
total mass
of the
reactants
must
equal
the
total mass
of the
products
in a
chemical reaction.
To balance an equation, we need to
multiply coefficients
until there's an
equal
amount of
atoms
on
both
sides
A
balanced
equation is an equation where the number of
atoms
on both sides are
equal
For combustion reactions:
Carbon
,
Hydrogen
, and
Oxygen
are the only gases that can be produced
What's the difference between reg. balanced equation, complete ionic equation, and net ionic equation?
Reg. balanced equation
: shows the
compounds
,
states
,
reactants
, and
products
Complete ionic equation
: shows
charges
,
ions
,
states
, and
precipitate
Net ionic equation.: just
ions
that make a
precipitate
Molar mass
Mass
of
one mole
of representative particles of a substance.
Molecular mass
of a
compound
the
mass
of one
molecule
of that compound
