What is difference between ∆H and ∆H°
Elena-2011 [213]

If it is shown as ∆H , then it means that a specific chemical reaction is undergoing heat in Kelvin(K). If it is shown as ∆H° , then it means that a specific chemical reaction is undergoing heat in Celsius(C⁰).

Hope this is the answer you are looking for mate!

If it is correct then please mark my answer as the brailiest! :)

Answer:

In chemistry, a reaction mechanism is the step by step sequence of elementary reactions by which overall chemical change occurs. A chemical mechanism is a theoretical conjecture that tries to describe in detail what takes place at each stage of an overall chemical reaction.

Three common ores of iron are FeO, Fe2O3, and Fe3O4. Iron ores are often reduced to elemental iron by heating in the presence of
brilliants [131]

Answer:

Answers are explained below

Explanation:

(a)

Oxidation number of iron :

FeO = +2

Fe2O3= +3

Fe3O4 = +2 and +3 since Fe3O4 is the mixture of FeO and Fe2O3.

(b) FeO + CO ----> Fe (s) + CO2

(c) In a pure iron metallic bond is exist between the particles of Fe. But in the form of ore metals forms ionic bond with the non-metals.

Hence the properties vary.

Yes carbon steel has greater strength than that of pure iron but retains the property of iron because no chemical reaction occurs between carbon and iron.

d)

Mixing of carbon in iron is a type of physical change since there is no chemical reactions occur between the carbon and iron. Carbon atoms diffuses in the place between the iron atoms.

(f) One of the property of non-metals are brittleness. It is non ductile .

So when the percentage of carbon increases its atoms also occupying more and more free places.

And increasing the brittleness. So the iron becomes less ductile.

e)
