Consider the reaction: 2mg + o2 → 2mgo
mg is ( ) and so is the ( )
o2 is ( ) and so it the ( )

*choices are oxidize, reduced, oxidizing agent, reducing agent.

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b
