Someone Help Please...

[adil786]

:o Its all about "balancing equations", can anyone help me:

Co2 + C = Co

Mg + HSO4 = MgSO4 + H2

Fe + H2O = Fe3O4 + H2

SO2 + O2 = SO3

Please... anyone , :o :( Jazakallah in advance.

[adil786]

OK im not completely thick, the first one should be "CO2"

i have a slight idea, but balancing equations is a nightmare for me.

It has been too many years since I had chemistry to help akhi. :(


...but I really enjoyed chemistry. I had an excellent teacher who liked the maritime cadets, so whenever we looked confused, he would relate the problem to a shipboard issue and we would get it. :up:

C02 + C = 2CO

2MG + 2HSO4 = 2MGS04 + H2

3FE + 4H20 = FE304 + 4H2

2S02 + 02 = 2S03

[adil786]

C02 + C = 2CO

2MG + 2HSO4 = 2MGS04 + H2

3FE + 4H20 = FE304 + 4H2

2S02 + 02 = 2S03

hmmm.. :rubeyes:...:D...:up:

LOOL...I'm sure they are right Inshallah. It's been a year since I did Chemistry A level :scratch:

If you don't understand, I can explain the process step by step Inshallah.

If you dont mind.,:o j/k

The first equation: Co2 + C = Co doesn't make sense :scratch:

what do you mean?

[Kubs]

Mg + HSO4 = MgSO4 + H2

Mg + HSO4 is the left side of the equation

MgSO4 + H2 is the right side of the equation


First look at the left side:

How mant Mg's (Magnesium) are there? One.


Now look at right hand side:

How many Mg's (Magnesiums) are there? One.


So Mg's are fine :up:




Now analyse the second one -------> HSO4

When you split this up and you get H and So4. Yeah?

You have ONE H on the left hand side

You have TWO H on the right hand side....since it says H2

SO all you have to do is add 2 infront of the H on the left hand side. Okay? :p



This is when it gets difficult :p

So far we have:

Mg + 2HSO4 = MgS04 + H2

But is it still balanced? No!

If you look at the equation...on the left hand side.... you have EIGHT oxygens.

Why?

Because the oxygen is 4.....and times it by 2....you get 8. Why do you times it by 2....because it's 2H.



But on the right hand side the oxygen is only 4.....S04 - see what I mean?

So to make both oxygens 8....you place a 2 infront of Mg in the right hand side.

So now we have:

Mg + 2HSO4 = 2MgS04 + H2


But it's STILL not balanced :crying:

Why?

Because now the Mg's on BOTH sides are NOT balanced :eek3:

On the left hand side we have ONE Magnesium

On the right hand side we have TWO Magnesium.

So basically...all you do...is you add 2 to the Mg in the left hand side.

And now you have this equation as your final answer:

2Mg + 2HSO4 = 2MGSO4 + H2


Is it balanced? Yes it is.

You have 2Mg on both sides

You have 2 H on both sides

You have 2 S on both sides

You have 8 oxygens on both sides.

[Kubs]

what do you mean?

I dunno...it just doesn't look right :scratch:

[adil786]

Cool,... i think i get all the balancing bits now, you just have to break it up..., right.

Thank you for your help. + rep. (already) :up: :D

Yep!

I edited some parts which were wrong......read over it again just to make sure Inshallah :up:

[adil786]

Doh! but it sounds sensible to me :torture:, i skimmed it first, ill read it thoroughly now lol :D

[Kasim2k7]

this is why i HATE chemistry

should av posted this on the education forum

2CO2 + 2C =4CO

2SO2 + O2 = 2SO3

THEY ARE SUCH AN EASY ONE! in my edexcel board we got such a difficult balancing that children are forced to cry at the time of examination!

Oh gosh! Chemistry.. haven't done this for... er... ok a long time so do verify these answers, I'm running of memory here.


You just have to keep track of the total numbers of atoms going around. If you need more somewhere, you'll have to balance out the others accordingly. (it helps to start with the atom you need the *most* of and go from there)

Co2 + C will give you two atoms of O and two atoms of C so that's (2)Co

CO2 + C = (2)CO

(2)Mg + (2)HSO4 = (2)MgSO4 + H2 (not (2)H2... the H has already been doubled)

(3)Fe + (4)H2O = Fe3O4 + (4)H2

(2)SO2 + O2 = (2)SO3
