The balanced chemical equation is given as:
2CH3CH2OH(l) → CH3CH2OCH2CH3(l) + H2O(l)
We are given the yield of CH3CH2OCH2CH3 and the amount of ethanol to be used for the reaction. These values will be the starting point for the calculations.
Theoretical amount of product produced:
329 g CH3CH2OH ( 1 mol / 46.07 g ) ( 1 mol CH3CH2OCH2CH3 / 2 mol CH3CH2OH ) (74.12 g / mol ) = 264.66 g CH3CH2OCH2CH3
% yield = .775 = actual yield / 264.66
actual yield = 205.11 g CH3CH2OCH2CH3

buffer is a substance that resists small change in the acidity of a solution
when an acid or base is added to the solution. Usually, a buffer involves a
weak acid or a weak alkali and one of its salt.</span>
The order do electron fill orbitals within the 3p sublevel is that they spread out, waiting until each orbital has one electron before doubling up.
<u><em>Explanation</em></u>
<u> </u> According to hund's rule every orbital in a subshell is singly occupied with one electron before any one orbital is doubly occupied,and all electrons in singly occupied orbital have the same spin.
when every orbital in a subshell is singly occupied by electrons it is then doubled, and the two electrons in same orbital have opposite spins
Both rods and cones are photoreceptor cells but rods are responsible for black and white vision while cones are responsible for color vision.
