2mg + o2 = 2mgo. show that mg is the limiting reactant?

If this helps let me know

The limiting reagent is the one that will be all used up if the reaction goes to completion. There is not enough of it present to use up all the other reagent (which is in excess). :)

If you are reacting in the atmosphere, then the oxygen is in excess (hopefully atmospheric oxygen will never be the limiting reagent) so since there is a limited supply of Mg that means that it is the limiting reagent

The independent variable is the type of music.the dependent variable is the pulse rate.the intervening variable is the age of the subject.if the mother does not like rock, her pulse is likely to not increase.the same might be true for the sister.the friend may like rap and gets excited.to establish cause/effect relationship, all of the subjects must be consistent.hope i .
