Science questions 10 points!

[From: ] [author: ] [Date: 12-02-11] [Hit: ]
iron ore (iron oxide) reacts with carbon monoxide to form iron and carbon dioxide.d.Lime stone (calcium carbonate) decomposes to form calcium oxide and carbon dioxide.e.carbon dioxide,Carbon monoxide,......
use the following information to write balanced chemical equations for these reactions which occur in the blast furnace

a.Carbon an oxygen react to from carbon dioxide.

b.Carbon dioxide reacts with carbon to form carbon monoxide

c. iron ore (iron oxide) reacts with carbon monoxide to form iron and carbon dioxide.

d. Lime stone (calcium carbonate) decomposes to form calcium oxide and carbon dioxide.

e. Calcium oxide reacts with impurities such as silica to form slag (calcium silicate)


Chemical formulae you may need:
carbon dioxide,CO2
Carbon monoxide,CO
Calcium carbonate, CaCO3
Calcium oxide, CaO
Calcium silicate, CaSiO
Iron oxide, Fe2O3
Carbon, C
Silica, SiO
Oxygen, O2

thanks guys any help is much appreciated and ill give 5 starts best answer!

a.Carbon an oxygen react to from carbon dioxide.

C + O2 -> CO2

(remember subscripts)

b.Carbon dioxide reacts with carbon to form carbon monoxide

CO2 + C -> 2CO

c. iron ore (iron oxide) reacts with carbon monoxide to form iron and carbon dioxide.

FeO2 + 2CO -> Fe + 2CO2

d. Lime stone (calcium carbonate) decomposes to form calcium oxide and carbon dioxide.

CaCO3 -> CaO + CO2

e. Calcium oxide reacts with impurities such as silica to form slag (calcium silicate)

2CaO + SiO2-> Ca2SiO4

remember the numbers infront of the element should be big but the ones afterwards they reference the number of atoms need to be small
