Identify the species undergoing oxidation and reduction.
a. `H_(2)S(g)+Cl_(2)(g)rarr2HCl(g)+S(s)`
b. `3Fe_(3)O_(4)(s)+8Al(s)rarr9Fe(s)+4Al_(2)O_(3)(s)`
c. `2Na(s)+H_(2)(g)+H_(2)(g)rarr2NaH(s)`

Identify the species undergoing oxidation and reduction. a. H2S(g) + Cl_2(g) gives 2HCl(g) + S(s)

In the reactions given below, identify the species undergoing oxidation and reduction : (i) H_(2)S (g) + Cl_(2) (g) rarr HCl (g) + S (s) (ii) 3Fe_(3)O_(4) (s) + 8 Al (s) rarr 9 Fe(s) + 4Al_(2)O_(3) (s) (iii) 2Na (s) + H_(2) (g) rarr 2 NaH (s)

Justify that the following reaction is a redox reaction H_2S_(g) + Cl_(2(g)) rarr 2HCl_(g) + S_(s)

Fe_(2)O_(3(s))+2Al_((s))rarr 2Fe_((s))+Al_(2)O_(3(s)) is a/an …………….
