What is the purpose of the periodic table?

Chemistry

Answer:

the periodic table is important because it is organized to provide a alot of information about elements and how they relate to one another in one easy-to-use reference. The table can be used to predict the properties of elements, even those that have not yet been discovered.

Based on the relative energy of the absorbed electromagnetic radiation, which absorber, a peptide bond or an aromatic side chain
alina1380 [7]

Aromatic side chain exhibits an electronic excited state that is closer in energy to the ground state.

  • In order to respond to this query, we must decide whether a peptide bond or an aromatic side chain is demonstrating an electronic exited state that is more closely related to the ground state in terms of energy.
  • When our energy is as low as possible, we are in the ground state.
  • What I want to point out is that if we can choose between the two options—peptide bond or aromatic side chain—without knowing the specific reasons, we can immediately rule out two potential answers.
  • Consider what we already know about energy, we have:

                                 E = h x c/λ

  • That indicates that when we have more energy, a wavelength decreases. Lower energy corresponds to higher wavelength.
  • Aromatic side chains absorb between 250 and 290 nm, while peptide bonds do so between 190 and 250 nm.
  • According to our breakdown, we have an electron excited state that is more closely related to the ground state in terms of energy as wavelength increases.

Thus, Aromatic side chain exhibits an electronic excited state that is closer in energy to the ground state.

A)
Karo-lina-s [1.5K]

A  formula unit of the nitrate salt of Q is Q(NO3)2.

<h3>What is IUPAC nomenclature?</h3>

The IUPAC nomenclature was put together by the international Union of Pure and applied chemistry in order to have a uniform way of naming compounds.

We shall now find the names of the compounds;

1) Na* and HPO4²- ; sodium hydrogen tetraoxophoshate V

2) Potassium cation and cyanide anion ; Potassium cyanide

3) Calcium cation and hypochlorite anion; Calcium oxochlorate I

Knowing that the  valency of NO3^- is one and that the compound formed between Q and  CO3²- has the formula QCO3 we can conclude that a formula unit of its nitrate salt is Q(NO3)2.

A student blows up a ballon and then places it in a very cold freezer the ballon shrunk why did it shrink
Rashid [163]
As temperature increases the speed of the molecules as well as the pressure also increases. Therefore the number collisions against the sides of the container (in this case the balloon) will increase because the pressure increased. When the temperature decreased when the balloon was put in a freezer the molecules slowed down, and the pressure decreased, so the number of collisions with the side of the balloon also decreased and the balloon shrunk. Hope that helps!
