1 mole of any substance (atoms or molecules)=6.022 x 10²³ atoms or molecules.

In this case:
1 mole of Zn=6.022*10²³ atoms.

Then:

1 mole of Zn---------------------6.022*10²³ atoms
x-------------------------------------5.6*10²⁴ atoms

x=(1 mole of Zn * 5.6*10²⁴ atoms)/6.022*10²³ atoms=9.0032... moles≈
≈9 moles

Answer: we have 9 moles in 5.6*10²⁴ atoms of Zn.

A chemist has synthesized two new dyes based on the molecular structure of plant-based dyes. The lowest energy absorption line f
Nimfa-mama [501]

Answer:

1. The dye that absorbs at 530 nm.

Explanation:

The dye will absorb light to promote the transition of an electron from the HOMO to the LUMO orbital.

The higher the gap, the higher the energy of transition. The energy can be calculated by E = hc/λ, in which h and c are constants and λ is the wavelength.

The equation shows that the higher the energy, the higher the gap and the lower the wavelength.

Therefore, the dye with absorption at 530 nm has the higher HOMO-LUMO gap.

Why did you have to form a diastereomeric salt from one of the enantiomers of ibuprofen? Choose two Group of answer choices It i
aleksklad [387]

Answer:

Correct answers: 2 and 3

Explanation:

1- correct would be: Isolation of ibuprofen is not dangerous, but it is necessary because only one enantiomer has effect on interaction with biologic <em>diana</em>

<em>2: Correct! This property of diastereomeric salts (differing solubilities) is really useful for the isolation of the original enantiomers</em>

<em>3: Correct! we can only observe their properties, like polirized light rotation or separation in an assimetric column for chromatography.</em>

4: correct would be: diastereomeric salts do not rotate light, they have lost the property of anantiomers that originated them

Which of the following statements is false concerning the formula of a compound?
aalyn [17]

Answer:

B. The number of atoms in a molecular formula is always greater than the number of atoms in an empirical  formula.

Explanation:

It is not always true that the number of atoms in a molecular formula is always greater than the number of atoms in an empirical formula.

The chemical formulae of a compound are of two main types;

  • The empirical formula is that which expresses the composition of a compound in the simplest whole number ratio.
  • The molecular formula shows the actual ratio of the atoms in a compound.

Sometimes the number of atoms in the molecular and empirical formula can be the same.

Also, the number of atoms in the molecular formula is always greater than that of the empirical formula when they are not the same.
