The O Layer. I believe. Or the A horizon
I think external forces acting on an object may include friction, gravity, normal force, drag, tension, or a human force due to pushing or pulling can be represented by a free body diagram.
Answer:
(a) Increasing the temperature adds heat which is a reactant shifting the equilibrium rightwards.
(b) Pressure has no effect since the change in the number of moles is zero.
Explanation:
Hello,
In this case, one could represent the given reaction as:

Since it is endothermic. Thus, solving the (a) statement, one identifies the heat as a reagent, that is why the reaction cools down as it progress, therefore, by increasing the temperature, heat is added, that is, a reagent is added, which shifts the equilibrium rightwards, in other words, more NO is produced so its concentration increases.
Furthermore, for the (b) statement, since the change in the number of moles is zero, based on the stoichiometric coefficients as shown below:

Such value implies that the pressure has no effect on the concentration, taking into account the following form of the law of mass action:

Thus, since
,
, so no effect in concentration is due to the pressure.
Best regards.
The answer is d noble gas because the very last column on the periodic table is all the noble gases
The status of the state of matter of a material defines the phase. Pellet currently case 16 is defined; three of which solid, liquid and gas are referred to as conventional cases. There are a total of 16 state currently defined, these classic except; liquid crystal, amorphous solid, magnetic regularly, superconducting, superfluid, the Bose-Einstein condensation, Rydberg molecules, plasma (ionized gas), the quark-gluon plasma, degenerate matter, Superkate, the stringy liquid and SuperCam mine. Daily life in general, solid materials, include liquid or gaseous, but outside world, 99% of the material in the universe plasma (ionized gas) is in the form.
