I hope you can understand this and i hope this helps.
<span>Speed increases with increasing temperature. Gas molecule speed follows the formula
v(average) = 8RT/(pi*M), where
M = molar mass (e.g., 0.002 kg/mole for hydrogen)
R = universal gas constant = 8.314472 J/(mole-degK)
T = temperature K
The ref. gives the derivation of this formula and other formulas for v(RMS) and v(most probable).</span><span>If u dont understand i can make it simpler just ask.</span>
There is not a force acting upon the book or the desk so nothing is moving it.
Answer:
D
Explanation:
From given choices it is D.
Mass would crystallize out : 24 g
<h3>Further explanation
</h3>
Solubility is the maximum amount of a substance that can dissolve in some solvents. Factors that affect solubility
-
1. Temperature:
-
2. Surface area:
-
3. Solvent type:
-
4. Stirring process:
We can use solubility graph to solve this.
solubility KClO₃ at 90°C=52 g
solubilty KCl₃ at 60°C= 28 g
Mass would crystallize out = 52 - 28 =24 g
Principal energy levels describe regions of space where electrons may be found.
the greater the average distance from the nucleus.
The principal energy level of an electron is the shell or orbit in which the electron resides with respect to the nucleus. This level is represented by the principal quantum number n.
The principal quantum number n represents the total relative energy of each orbit. The energy level of each orbit increases as the distance from the nucleus increases. A set of orbitals with the same n value is often called the electron shell.
Only seven energy levels are required to contain all the electrons in any atom of any currently known element. As mentioned earlier, the energy associated with the energy level increases as the distance from the nucleus increases.
