What is Electromagnetic Spectrum ?

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.

What is the volume of a substance that has a mass of 20 g and a density
of 4.0 g/ml?

Answers

Answer:

The answer is 5 mL

Explanation:

The volume of a substance when given the density and mass can be found by using the formula

[tex]volume = \frac{mass}{density} \\ [/tex]

So we have

[tex]volume = \frac{20}{4} \\ [/tex]

We have the final answer as

Answers

Answer:

The answer is 3.44 g/cm³

Explanation:

The density of a substance can be found by using the formula

[tex]density = \frac{mass}{volume} \\[/tex]

From the question

mass = 17.2 g

volume = 5 cm³

We have

[tex]density = \frac{17.2}{5} \\ [/tex]

The oligopeptide MNQSYGRLVSRAAIAATAMASLIKIFAWWY was cleaved by reaction with trypsin. Trypsin is a serine protease that hydrolyses peptide chains at the proteins at the carboxyl sides of the amino acids lysine or arginine. The products of the digestion are then subjected to ESI TOF-MS in positive ion mode with the peptides in a pH 2 solution. a. Calculate the mass of each cleavage product based on their amino acid sequence and determine their predominant charge state at pH 2. Which product will reach the detector first

Answers

Answer:

Follows are the solution to this question:

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.

PLEASE HELP!!! Do you think the number of animals that eats plants is related to the number of plants?

Answers

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.

How many moles of Hions are present in the following aqueous solution?
3.3 mL of a 0.65 M nitric acid:

Answers

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.

Give the net ionic equation for the reaction (if any) that occurs when aqueous solutions of lithium sulfide and copper (II) nitrate are mixed.

Answers

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).

f is the frequency

h is the Planck's constant which is

6.626 × 10-³⁴ Js

From the question
