We usually expess solubility as the maximum number of grams of of a solute that will dissolve in 100 g of solvent.
For example, at 20 °C, the solubility of <em>sodium chloride</em> is <em>35.89 g/100 g water</em>.
I think the correct answer is b. Temperature is proportional to the average kinetic energy so when temperarure rises so will the average kinetic energy. I hope this helps. Let me know if anything is unclear.
Hg²⁺ + 2CH₃COO⁻ → Hg(CH₃COO)₂ mercuric acetate
N2 + O2 = 2No
The Q value of the above equation is calculated as below
Q =[ No]^2/{(O2)(N2)}
Q=[0.05]^2/{(0.95 )(0.65)} = 0.00404
the reaction will shift to the left since Q> Keq that is 0.0404 > 0.0025
The element with electron configuration 1s² 2s² 2p⁶ will most likely not react with an element having seven Valence electrons.
The electron configuration of the element in discuss is 1s² 2s² 2p⁶.
The element has enough electrons to fill it's energy level, n = 2 shell.
- In essence, the element in discuss is unreactive as it has attained it's octet configuration and as such is neither in need of an electron nor ready to donate an electron.
As such, although an atom having seven Valence electrons is highly electronegative and as such is an electron attractor, the element with the full octet configuration does not react with it.
This unreactive nature of noble gases is attributed to the full octet configuration of noble gases.
P.S: The electron configuration above is the electron configuration of Neon, Ne.
