the developing chamber is not covered with plastic wrap during the development of the chromatogram. will the Dion value for the

cation be greater than or less than the actual value as a result of this technique error?

Answer:

The correct answer is less than the actual value.

Explanation:

The Dion value of the cation would be less of the actual values because the solvent wouldn’t travel on the paper properly. The non-polar molecules in the mixture will have little attraction for the water molecules attached to the cellulose, so they will spend most of their time dissolved in the moving solvent. Molecules like this therefore travel far above the paper that carries the solvent.

Have a nice day!

In addition to those in Table 14.3, other less stable nitrogen oxides exist. Draw a Lewis structure for each of the following:(c
Natalka [10]

Lewis structure for each of the following N₂O₃ with no N¬N bond is attached below.

Even though pi symmetry occupies the antibonding orbitals of NO, this is unimportant after the dimer forms. A sigma connection exists. The enthalpy of the newly formed sigma bond in the dimer is low because the loss of a particularly distinctive set of single-electron resonance forms that were available for no monomer offset the net gain in bond. When the whole free energy is taken into account, there is no gain because the entropic effects are on the order of 1030kJ/mol, and dimerization is entropically disfavored at G=17kJ/mol. Therefore, any little increase in enthalpy is cancelled out by the loss of entropy.

How many grams of zinc metal will react completely with 5.4 liters of 2.8 M HCl? Show all of the work needed to solve this probl
Assoli18 [71]
The reaction is
<span>Zn (s) + 2 HCl (aq) ---->  ZnCl2 (aq) + H2 (g)
which is already balanced
5.4 L of 2.8 M HCl contains 
5.4 L (2.8 M) = 15.12 moles HCl
The amount of Zinc that will react completely with the acid is
15.12 mol HCl (1 mol Zn / 2 mol HCl) (65 g Zn/1 mol Zn) = 491.4 g Zn
