Answer:
B. Both electrons of Mg should be transferred to one O.
Explanation:
Metals react by loosing electrons while non metals react by gaining electrons.
Reactions occur as each element strives to attain an octet electron configuration in the outer energy level.
It is easier for magnesium to loose 2 electrons than to gain six because loosing the two requires less energy.
Oxygen on the other hand reacts by gaining the two electrons lost by magnesium since it is easier to gain the two than to loose the six. Gaining the two electrons for oxygen requires less energy than loosing the six.
In summary, magnesium looses two electrons that are transferred to oxygen.
If I'm correct the answer should be a series circuit :) Hopefully this helps you out
The hours taken for concentration to decrease from 0 to 74 min. to 0.21 m is 91.7 hours.
<h3>What is the rate law of a reaction?</h3>
Rate law depicts the rate of a chemical reaction depend on the concentration of the reactant.
The given reaction is second order reaction
Thus, the hours taken for concentration to decrease from 0 to 74 min. to 0.21 m is 91.7 hours.

Answer:
Dihydrogen monoxide is one of the scientific names of water having the formula H2O, where H2 "dihydrogen" is a double hydrogen (Latin Hydrogenium — hydrogen), and O is "monoxide" (oxygen).
