Answer:
The Yerkes-Dodson Law suggests that there is a relationship between performance and arousal. Increased arousal can help improve performance, but only up to a certain point.
Explanation:
Answer:
Answer is C atoms of different elements are the same
iron has two oxidation states +2 and + 3 there are two possible equations for the redox reaction - comparatively speaking, ferrous compounds are easier to hydrolyze than their ferric counterparts.
<h3>What is Redox reaction ?</h3>
Compared to ferric oxide, ferrous oxide is more basic in makeup. Comparatively speaking, ferrous compounds are more ionic than their ferric counterparts. Due to the fact that ferrous compounds are more ionic than their corresponding ferric ones, they are less volatile.
The greater positive charge of ferric compounds, however, makes them easier to hydrolyze than the comparable ferrous ones.
The quantity, kind, and distances of the iron atom's neighbors all contribute to their stability. Because each Fe atom is only weakly linked together by three electrons, which makes them susceptible to being dragged away by strong electronegative neighbors like oxygen, both types of ions are stable.

Answer:
4.17e+22 atoms of tin are present in the cube
Explanation:
We don't require the size of the cube. With the mass and the molar mass of tin = 118.7 amu we can find moles of Tin. As 1 mol = 6.022x10²³ atoms we can find the number of atoms:
<em>Moles Tin:</em>
8.21g * (1mol / 118.7g) = 0.0692 moles Tin
<em>Atoms Tin:</em>
0.0692 moles Tin * (6.022x10²³ atoms / mol) =
<h3>4.17e+22 atoms of tin are present in the cube</h3>
