Question

*HELP ASAP PLEASE QUESTION IN PICTURE*

Answer 1

I'd say Mg.

Step-by-step explanation:

The reducing agent is the agent that is oxidized (losses electrons).

The oxidizing agent is the agent that is reduced (gains electrons).

For the mentioned reaction:

2Mg + O2→ 2MgO.

Mg (oxid. no. = 0) is converted to MgO (oxid. no. of Mg = +2), which means that Mg losses 2 electrons and is oxidized.

So, the reducing agent is Mg.

Answer 2

answer is: O

o goes from 0 to -2, so it is the element that is reduced

hope this helps! ;)
