Extracting metals in the middle of the activity series — task. Chemistry CBSE Live product, Class 10.

Answer the following question:

Aluminium is used with a compound, X, in the process of joining railway tracks.

i. Identify compound 'X'.
ii. Mention the name of the reaction involved .
iii. Write the balanced chemical equation for this reaction.

i. Name the compound 'X'.

Iron oxide (\(FeO\))
Iron (III) oxide (\(Fe_2O_3\))
Iron oxide (\(Fe_2O_4\))
Iron (II) oxide (\(Fe_2O_3\))

ii. The name of the reaction is the .

iii. The equation is

\(FeO(s)+2Al(l)→2Fe(l)+Al_2O_3(s)+Heat\)
\(Fe_2O_3(s)+2Al(s)→2Fe(l)+Al_2O_3(s)+Heat\)
\(Fe_2O_3(s)+2Al(s)→Fe_2(s)+Al_2O_4(s)\)
\(Fe_2O_4(s)+2Al(l)→2Fe(s)+Al_2O_3(s)+Heat\)
