Need help in Chemisrty P3 :)

This is easy but just making sure:

Chemical equation which helps to increase temperature in blast furnace?

waste gases from blast furnace?

 

[Ali4lyf]

the most highest temp increase in on when Carbon reacts with Air(Oxygen) Making C02(Carbon dioxide)

Waste gas is only Co2.

Ok..for my mock paper....the question was....name two of the waste gases in blast furnace....so yeah

 

[Ali4lyf]

c02 is the main gas but if they ask any other gas than that . It would be O ( Oxygen )

oki...thankx!

 

[Ali4lyf]

hey read pm =)

I think its Nitrogen? The other gas...

 

[Nibz]

C + 02 -> CO2 ( this helps increasing the temperature)
Carbon Dioxide mainly.

 

[Xenarra]

I think its Nitrogen? The other gas...

no...nitrogen cant be it.....there is no involvement of nitrogen in blast furnace

 

[Ali4lyf]

So I was right yea?

Captain @ : Nitrogen would be on other place not in blast furnance

I didnt prepare from past papers just only 1 year :sorry:
I dont know what is going to happen tommorow please pray for me all of you
Thanks.

REGARDS,

no...nitrogen cant be it.....there is no involvement of nitrogen in blast furnace

On Wikipedia I read that Nitrogen is in there too...

 

[Ali4lyf]

I dont follow wiki pedia or wiki leaks

 

[CaptainDanger]

Ok... All the very best for the paper then....

ow really? coz i din study that :/
this is all the reactions i know of in blast furnace:
C + O2 = CO2
CO2 + C = 2CO
Fe2O3 + CO = Fe + CO2
CaCO3 = CaO + CO2
CaO + SiO2 = SiCaO3

 

[Ali4lyf]

we follow book .
Nitrogen could be for A levels not for IGCSE em sure..

 

[Nibz]

Nitrogen is definitely one of the waste gases.
It is not an A-level concept. You should know this at IGCSE level!

 

[Parfals]

check dis viewtopic.php?f=24&t=9387 i m nt sure bt might help u fr other stuffs!

 

[cupcake76]

its silicon oxide !!

 

[jbatcampnou]

Yea the other one is Nitrogen. It's a constituent of air. Read this somewhere in a CIE enorsed IGCSE Chemistry book. THough haven't found it in any past papers I've done 'till now. Thing is, if they do ask for two gases, Nitrogen is the one, but i don't think they will..
