Explanation:

The creation of four fragments,  

(n endpoint) MNQSYGR (c endpoint)  

Weight of the molecular = 854.92

Load = 2

[tex]\to \frac{mass}{Load}[/tex] = 427.46

(n endpoint)RLVSR (c endpoint)

Weight of the molecular = 629.76

Load = 3

[tex]\to \frac{mass}{Load}[/tex]= 209.92

(n endpoint) AATAMASLIK (c endpoint)

Weight of the molecular = 976.20

Load at pH(2). = 2

[tex]\to \frac{mass}{Load}[/tex]= 442.50

(n endpoint) IFAWWY (c endpoint)

Weight of the molecular = 885.03

Load= 1

[tex]\to \frac{mass}{Load}[/tex]= 885.03

It is apparent that RLVSR is the smallest mass ration for this peptide that is detected in the first place.

Answer:

S²⁻(aq) + Cu²⁺(aq) ⇒ CuS(s)

Explanation:

Let's consider the molecular equation that occurs when aqueous solutions of lithium sulfide and copper (II) nitrate are mixed.

Li₂S(aq) + Cu(NO₃)₂(aq) ⇒ 2 LiNO₃(aq) + CuS(s)

The complete ionic equation includes all the ions and the species that do not dissociate in water.

2 Li⁺(aq) + S²⁻(aq) + Cu²⁺(aq) + 2 NO₃⁻(aq) ⇒ 2 Li⁺(aq) + 2 NO₃⁻(aq) + CuS(s)

The net ionic equation includes only the ions that participate in the reaction and the species that do not dissociate in water.

S²⁻(aq) + Cu²⁺(aq) ⇒ CuS(s)

The net ionic equation includes only the ions that participate in the reaction and the species that do not dissociate in water.

S²⁻(aq) + Cu²⁺(aq) ⇒ CuS(s)

The molecular equation that occurs when aqueous solutions of lithium sulfide and copper (II) nitrate are mixed.

Li₂S(aq) + Cu(NO₃)₂(aq) ⇒ 2 LiNO₃(aq) + CuS(s)

The complete ionic equation includes all the ions and the species that do not dissociate in water.

2 Li⁺(aq) + S²⁻(aq) + Cu²⁺(aq) + 2 NO₃⁻(aq) ⇒ 2 Li⁺(aq) + 2 NO₃⁻(aq) + CuS(s)

The net ionic equation includes only the ions that participate in the reaction and the species that do not dissociate in water.

S²⁻(aq) + Cu²⁺(aq) ⇒ CuS(s)

Thus, net ionic equation is S²⁻(aq) + Cu²⁺(aq) ⇒ CuS(s).

Answer:

Yes

Explanation:

As the number of animals that eat plants increase, the number of plants decrease. This is because the animals are eating a larger and larger number of plants and reducing the population.

When the number of plants gets too low, the animals will not be able to survive, and they will start to decrease in numbers. In turn, the plants will increase again. Eventually, they will reach an equilibrium.

Answer:

frequency f = velocity of light (c)/wavelength

therefore, wavelength =

velocity of light /frequency

= 3 x 10^8/ 5.43 x 10^-12

= 0.552 x 10^20.

Answer:

Its A

Explanation:

Green, blue, indigo lists three parts of sunlight that make up some of the visible spectrum. Hence option with green, blue, indigo is correct.

Electromagnetic spectrum is nothing but the range of wavelengths or frequencies on which electromagnetic radiation extend. it is whole distribution of electromagnetic waves according to frequency or wavelength. Electromagnetic wave is nothing but a photon which carries energy. Photon has frequency, wavelength as well as amplitude.

Electromagnetic spectrum is show in figure.

Range from 4000 angstrom to 7000 angstrom from violet to red respectively shows the visible light

Infrared light is nothing but the heat we feel from the sun. and ultraviolet light is blacked by ozone layer. we can calculate exact value of temperature of the sun rom Stephan's forth power law.

Green, blue, indigo, red and oranges are the colors from visible light, therefore they are part of visible light.

Explanation:

The chemical compound known as Borates has the Molecular Formula: BO3^-3. It has the shape of a triangle but Borates can form multiples ones that is to say quadrangles. Also, as a result of the fact that the octect is not complete, Borates are used as lewis Acid.

The oxygen present in Borates is/are directly attached to the central atom that is Boron while in non silicates the oxygen(s) that may be present is not directly attached to the central atom.

Answer:

Nitric acid is a strong acid meaning it completely dissociates in water. Therefore, you can say that the concentration of H+ ions in solution is the same as the concentration of the acid (molar concentration). So once you have that, you can use the pH formula to find the pH of the acid.

pH = -log[H+]

So if you have .15 M HNO3 the pH is 0.82.

But, if you have a different concentration, the pH will change.
