Question 5

in their compounds, metals:

are assigned positive oxidation numbers

are assigned negative oxidation numbers

are assigned oxidation numbers of zero

can be assigned any oxidation number that balances the equation

question 6

in the reaction, zn (s) + fe+2 (aq) imported asset zn+2 (aq) + fe (s), the oxidizing agent is:

the zn

the fe

the zn+2

the fe+2

For the first question, the correct answer would be the first option. In their compounds, metals are assigned positive oxidation numbers. They have positive oxidation reactions since when in their compounds they are the one to donate their electrons making them positive from their neutral state. For the second question, the correct answer would be the last option. The oxidizing agent would be the iron ion or the Fe2+. The oxidizing agent is the one that is being reduced in the reaction since it accepts the electrons given by the reducing agent. The reducing agent would be the zinc metal.
