Explanation / Answer

OXIDIZE: lose electrons REDUCE: gain electrons 1) 2Al0(s)+3Cl20 (g)>2Al+3 Cl-13(s) substance oxidized: Aluminum is losingelectron because its oxidation state went from 0 to +3 as shownabove. which means it lost 3 electrons, therefore it is beingoxidized. substance reduced: Cl went from 0 to -1oxidation state which means it gained one electron. therefore it isreduced. oxidizing agent: oxidizing agent causes theother element to lose electrons and gains electrons itself.therefore, Cl is the oxidizing agent. reducing agent: reducing agent causes theother elecemt to gain electrons and lose electrons it self.therefore, Al is the reducing agent. 2) 8H+1 (aq)+Mn+6O-24- (aq)+5Fe 2+(aq)--->5Fe 3+ (aq)+Mn 2+(aq)+4H2O (l) substance oxidized:  Iron is losingelectron because its oxidation state went from +2 to +3 asshown above. which means it lost 1 electrons, therefore it isbeing oxidized. substance reduced: Mn went from +6 to +2 oxidation state which means it gained twoelectrons. therefore it is reduced. oxidizing agent: oxidizing agent causes theother element to lose electrons and gains electrons itself.therefore, Mn is the oxidizing agent. reducing agent: reducing agent causes theother elecemt to gain electrons and lose electrons it self.therefore, Fe is the reducing agent. 3) Fe+2 S-2 (s)+3N+5O-23-(aq)+4H+(aq)--->3N+2O-2(g)+S+6 O-242- (aq)+Fe 3+ (aq)+2H2O(l) substance oxidized:  Fe is losingelectron because its oxidation state went from +2 to +3 asshown above. and sulfur went from -2 to +6 which means itlost 8 electrons, therefore S and Fe are being oxidized. substance reduced: Nitrogen wentfrom +5  to +2  oxidation state whichmeans it gained 3 electrons. therefore it is reduced. oxidizing agent: oxidizing agent causes theother element to lose electrons and gains electrons itself.therefore, N is the oxidizing agent. reducing agent: reducing agent causes theother elecemt to gain electrons and lose electrons it self.therefore, S and Fe are the reducing agent. 4) Zn0 (s)+2H+1 Cl-1(aq)>Zn+2 Cl-12(aq)+2H02(g) substance oxidized:  Iron is losingelectron because its oxidation state went from +2 to +3 asshown above. which means it lost 1 electrons, therefore it isbeing oxidized. substance reduced: Mn went from +6 to +2 oxidation state which means it gained twoelectrons. therefore it is reduced. oxidizing agent: oxidizing agent causes theother element to lose electrons and gains electrons itself.therefore, Mn is the oxidizing agent. reducing agent: reducing agent causes theother elecemt to gain electrons and lose electrons it self.therefore, Fe is the reducing agent. 3) Fe+2 S-2 (s)+3N+5O-23-(aq)+4H+(aq)--->3N+2O-2(g)+S+6 O-242- (aq)+Fe 3+ (aq)+2H2O(l) substance oxidized:  Fe is losingelectron because its oxidation state went from +2 to +3 asshown above. and sulfur went from -2 to +6 which means itlost 8 electrons, therefore S and Fe are being oxidized. substance reduced: Nitrogen wentfrom +5  to +2  oxidation state whichmeans it gained 3 electrons. therefore it is reduced. oxidizing agent: oxidizing agent causes theother element to lose electrons and gains electrons itself.therefore, N is the oxidizing agent. reducing agent: reducing agent causes theother elecemt to gain electrons and lose electrons it self.therefore, S and Fe are the reducing agent. substance oxidized:  Fe is losingelectron because its oxidation state went from +2 to +3 asshown above. and sulfur went from -2 to +6 which means itlost 8 electrons, therefore S and Fe are being oxidized. substance reduced: Nitrogen wentfrom +5  to +2  oxidation state whichmeans it gained 3 electrons. therefore it is reduced. oxidizing agent: oxidizing agent causes theother element to lose electrons and gains electrons itself.therefore, N is the oxidizing agent. reducing agent: reducing agent causes theother elecemt to gain electrons and lose electrons it self.therefore, S and Fe are the reducing agent. 4) Zn0 (s)+2H+1 Cl-1(aq)>Zn+2 Cl-12(aq)+2H02(g) substance oxidized:  Zn is losingelectron because its oxidation state went from 0 to +2 asshown above. which means it lost 2 electrons, therefore it isbeing oxidized. substance reduced: H wentfrom +1  to 0 oxidation state which means itgained one electron. therefore it is reduced. oxidizing agent: oxidizing agent causes theother element to lose electrons and gains electrons itself.therefore, H is the oxidizing agent. reducing agent: reducing agent causes theother elecemt to gain electrons and lose electrons it self.therefore, Zn is the reducing agent. HOpe that helps substance oxidized:  Zn is losingelectron because its oxidation state went from 0 to +2 asshown above. which means it lost 2 electrons, therefore it isbeing oxidized. substance reduced: H wentfrom +1  to 0 oxidation state which means itgained one electron. therefore it is reduced. oxidizing agent: oxidizing agent causes theother element to lose electrons and gains electrons itself.therefore, H is the oxidizing agent. reducing agent: reducing agent causes theother elecemt to gain electrons and lose electrons it self.therefore, Zn is the reducing agent.
