Answer #1

1) 2Fe(s)+3Cl2(g)----------->2FeCl3(s)

a. Oxidized species: Fe (as its oxidation state changes from 0 in Fe to +3 in FeCl3).

b, reduced species: Cl2 (as its oxidation state changes from 0 to -1 )

c. oxidizing agent: Cl2(g) (got reduced)

d. reducing agent: Fe(s) (got oxidized)

2) Mg(s) +   2H2SO4(aq)--------->MgSO4(aq)   +   SO2(g)   + 2H2O(l)

a. Oxidized species: Mg(s) (as its oxidation state changes from 0 in Mg to +2 in MgSO4).

b, reduced species: H2SO4 (as the oxidation state of S changes from +6 to +4 in SO2 )

c. oxidizing agent: H2SO4 (got reduced)

d. reducing agent: Mg(s) (got oxidized)
