L5 : Chemical Equation - Chemical Reaction, Science, Class 10 Video Lecture - Class 12

hello friends this video on chemical
reaction when equations part 5 is
brought to you by exam clear calm no
more fee from exam before watching this
video please make sure that you have
watched part 1 to power 4 so else of
uric acid is added to Koh dashing
hydroxide I think this give you put a
stem cell Frankie to sf4 plus water now
again if you see is there any sulfate
compounding yes we have a so for here
except for here than the first by adding
little bit take potassium and then
hydrogen it monster correct so you see
the potassium part so we have one here
one here it's all balanced reactant
product second mother potassium part
there was only one potassium here this
too / - it is not balanced right so
let's multiply exhibit to do balance it
so what you get now here is H 2 so 4
plus 2 Koh gives
k2so4 plus s 2 right now let's again see
the balance part and we have set for k
NH sulfate part is 1 here 1 here
reactant and product then we have this
next is potassium part is 2 here and 2
here all balanced hydrogen bond to
hydrogen plus 200 will take hydrogen
from here because H was a compound but
still does not here so we are not
considering this right so hydrogen do
from here to from a variety and here we
have only 2 hydrogen
correct does not balance so we need 2
more attention here a multiplying so
what you get now here it is s 2 s a 4
plus 2 Koh gives k2so4 plus h2o h2o now
let us again check the balance thing and
so for ki hlo sulfate has 1
one here valance patrasche name is -
here - here balance
hydron is 2+2 here 4 here and here also
for oxygen is 2 here 2 here and here
also 2 RC so if you see everything is
balanced right so this is also balanced
equation it's a last example of this
balanced chemical equation little tricky
so please buy th and here so we have p
o4 p or for both side so p or for is my
one compound oh Sh both sides we have
oho so one combo then take calcium then
I am left with hydrogen only right
correct because this guy I took this guy
I took calcium Hanson the money these
are my order of priority correct so
first let's check if they're balanced or
not we'll take po4 po4 it has only one
it has to correct is reactant is product
there is one this guy is to correct so
let's multiply this guy with 2 you get 2
P over both side so what you get is 2
h3po4 plus calcium oxide give h o h plus
ca3 po4
now again let's compare so pure for we
have 1 2 2 here here also we have 2 so
Kyogre in balanced now we'll see the
which part which part we have to hair
reactant in product we have only one so
that means - guys also not balanced so
let's multiply this guy with two correct
so what you get here is two h3po4 + c
a.o h2 is equal to 2 HOH
Plus ca3 po4 correct now like it's mean
see po4 heh so P or fourth party if you
see two to both sine H bar there is -
there is - here
calcium bod is one Cassie - three
calcium here right one we have three so
multiply this guy every kind because
it's not balanced so what you get is 2 s
3 P or four plus three CEOs - gives 2h o
h plus C it's me fearful it's again see
the equations here so again we have two
your for Oh heh
so po4 part we have 1 here 1 into 2 here
then we have 2 here Oh H part we have
not 3 into 2 6 OS Sharia and here we
have only 2 H it's not balanced right so
let's again multiply this guy with three
it's not balanced let's multiply this
guy III correct so let's see what you
get
so now you get to h3po4 +3 calcium
hydroxide is equal to 6 X over H last CA
3 here now let's again see the balance
thing so we have P or 4 o H calcium
hydrogen and we have reactant and
product so we have P of 4 here - piece
so we have to your four degrees right
this guy is 2 into 1 this guy's 2 1 into
2 o H part is 3 into 2 6 y is part is 6
into 1 6 CA part is 3 into 1 3 see a
part is 1 into 3 is 3 now left with
hydrogen hydrogen here is 3 into 2 6
here 6 into 1 6 so you see everything is
but that I can say that this is my
balanced chemical reaction cut
now let us take some example here we
write a balanced chemical etching for
hydrogen plus chlorine is equal to
hydrogen chloride so we have hydrogen we
have chlorine both two gases right we
know that H in the CH 2 form including
this in C and D form this gives a CL
naught is not balanced in two balances
so the order will be first flowing and
then hydrogen correct so chlorine if you
see there are two glowing items they
only one clean item here in product so
let's multiply this guy vector so
watering it is 2 plus here who is going
to do I see now let's compare the
chlorine hydrogen part chlorine they are
in reactant layer 2 and throat out there
to hydrogen reacted to and product so if
you see that it is a balanced chemical
equation easy question the only thing
that you should know that hydrogen is h2
and chlorine is see it will take some my
samples can try the balanced chemical
equation for billion for I plus L
himself into very insulting plus so the
equation is it like this barium chloride
aluminum sulfate so a mix I I expect
that you know how to or the form of
every in sulphate is equal to barium
sulfate I expect that we know the
formula barium sulfate plus aluminum
chloride alcl3 this things you already
know the formulas of various compounds
these compounds are familiar to us so
yes rotors formula now let's see if this
balance or not first any compound we
have yes I suppose then any metal yes we
have an even value let me have any
normal yes chlorine this is the four
thing we have so let's balance this top
you balance this first see the dismal
reactant if let me write here actually
I will use this only answer is my
reactant is matter so sulfate we have
three here and you have one here this is
non balance we will multiply this is a
303 sulphate they are oneself at here so
let's multiply so what you get is barium
chloride last term in salt fail even
three barium sulfate plus mu Q right now
let's again check so I will again check
that so we have a so for ya so sulfide
we have three here and three here
Elmarie we have two here and you have
only one here it's not balanced so let's
multiply this gamma T so now what you
get is barium chloride plus L mean IAM
sulfate is equal to three barium sulfate
last steer meal flow right correct yes
again teeth it is balanced or not so we
have sulfate you have a uni and we have
been sulfate we have how many three here
and three here balanced ammonium we have
two here two here and balanced barium we
have one here and three here it's not
balanced right we have three here and we
have only one here it's not balanced so
what we loo will multiply this guy with
three so what if it is three be easy L
to last year to vessel for three is
equal to three barium sulfate plus te
lcamp1 writes again check so we have s
o4 l VA and CF correct the Mary Acton is
that product sulfate part is three here
and three here L me impart is
two here and two here behave God is
three here and three here for in part is
3 into 2 6 here and 2 into three 6s we
see that they all balance this guy is my
balance Jimmy can same thing the only
thing is that they are checking if you
know the formula bearing rise early and
sell fair variants of Edom aluminum
