so in this video i'm going to show you how to balance chemical equations
in this example let me show you what happens when you mix iron
which is at p
with oxygen
which is the other two
and when they we have together you get the compound
efi two
all three
or what is more commonly known as roster
so this is a good example to show what happens when you leave your bicycle
in the rain
your bicycle which is made mostly of steel
and still is ninety five percent buyer
and iron
mixes with the rain which is just water
and water contains artesian
so that i had the oxygen we have together
and then you get this annoying brown substance on your bike which is at b two
oh three or four
but you know as russ
so let's get started right away and start bouncing this equation
so first let's start with the iron we need to have the same number of iron on
the left hand side
as we do on the right hand side
and so does the motives that he had one
adam of iron and on the right hand side we have to adams iron
so sitting in the making equal
adequate to welcome those of iron on the left hand side
so now as do the same thing for the oxygen notice on the left hand side how
we have to adams of oxygen
and on the right hand side we had three items of oxygen
uh... we need to make this equal
so a lot inside arnold apply it to adams
of oxygen
with one and a half molecules
one-and-a-half times to is equal to three
in on the right hand side we also have three similar accidents are balanced
so now we have the same exact number of ironing oxygen on the left hand side as
we do on the right hand side
so our returns with this problem
of the answer to that question is no
because we can never have half a molecule notice how we have one and a
half molecules
artesian
so how do we get rid of half molecule
the answer to that question is multiply both sides by two
so that's going to do right now i'm gonna multiply both sides of the
equation by two
so let's start with the iron know so we have to molecules of iron
two times to zepa before
so now we have four molecules of iron
sadat's move on to the oxygen knows how we have what and a half
molecules artesian multiply what happens to you
pegasus three modules oxygen
and whatever you do too one-sided you need to do to the other side
so no need to apply the right side by two
knows how we have one molecule of rust on the right hand side
one times to is equal to two
so now we have to molecules address on the right hand side
scenario completely balance the equation but let's double check to sioux make
sure that we got her answer
notice on the left hand side how we have one and a
uh... of iron
ng multiply by four molecules so we have four total lion
in on the right hand side we have
two atoms of iron
be multiplied by two molecules so we also have
or total iron
so those double check her oxygen notice on the left hand side how we have to
adams of oxygen being multiplied by three molecules
so we have six total oxygen
and on the right hand side we have
three
adams of oxygen being multiplied by two molecules
so we also have six
colosseum
scenario double-check your answer we had four irons and six oxygen is on the left
hand side and we also have or irons kids and the right hand side
but this is an easy example i'm going to be making some more videos once more
difficult to impose so stay tuned
according to your hotel so until my next one
i will see you later
