In a redox reaction, a substance is the oxidizing agent if it     causes something else to be oxidized     causes something else to be reduced     doesn't change oxidation state     is oxidized

In a redox reaction, explain why the species that gets oxidized is called the reduction agent

In oxidation-reduction reactions: Oxidation and reduction reactions can never occur simultaneously The species that is oxidized loses electrons Oxidation is the gain of electrons The species that is reduced loses electrons The charge on the species that is oxidized goes down

What is the oxidation number of carbon in CO2? +1 +2 +3 +4 -1 -2 -3 -4
