Answer:
El aire es una mezcla de gases que forman la atmósfera, es por ello que se encuentra en todas partes. Sus componentes principales son el nitrógeno, oxígeno, dióxido de carbono, neón, helio, entre otros.
Answer:
In this case, a neutral atom with 12 protons will have 12 electrons. On the periodic table, the atom with 12 protons is magnesium, which is in group 2 . Therefore, it will most likely lose 2 electrons to have 10 electrons, and form a noble gas configuration. So, magnesium becomes Mg2+ .
The number of moles of iron produced can be obtained by the use of stoichiometry.
<h3>What is stoichiometry?</h3>
The term stoichiometry has to do with mass - mole or mass - volume relationships. Stoichiometric relationships could be used to determine the amount of substance.
Now the reaction equation as well as other details are not shown in this question hence a numerical anwer can not be provided. As such, we can know that the balanced reaction equation can always be used to obtain the amount of iron by stoichiometry.

Distilled water and sealed container are in equilibrium when these objects do not exchange more heat.
<h3>What is thermal equilibrium?</h3>
The expression 'thermal equilibrium' makes references to the phenomenon by which two objects interact with each other to exchange heat energy.
Objects in contact can transfer heat to reach a thermal equilibrium state where the temperature is the same for both objects.
In conclusion, distilled water and sealed container are in equilibrium when these objects do not exchange more heat.
