Answer:
K(eq) = 15 (2 sig. figs)
Explanation:
Rxn: CO(g) + 2H₂(g) ⇄ CH₃OH(l)
C(eq): 0.150M 0.360M 0.282M
Keq = [CH₃OH(l)]/[CO(g)][H₂(g)]
= (0.282M)/(0.150M)(0.360M)²
= 14.50617284 (calc. ans.)
= 15 (2 sig. figs.)
Answer:
Sodium has one valence electron. Valence electrons are electrons found in the outermost shell of an atom. The shell number representing the valence shell will differ depending on the atom in question. For sodium, which is in the 3rd row of the periodic table, the valence electrons will be found in the 3rd shell.
The special properties of surface layers, that is, the thin layers of a substance at the boundary of contiguous bodies, mediums, or phases. These properties result from the excess free energy of the surface layer and from the special features of the layer's structure and composition.

<span>When a solid is dissolved, the state transitions to a liquid - a higher entropy substance than the previous solid. Therefore, the entropy of the system will increase, and, by convention, the sign of delta S will be positive.</span>
