6. Determine the wavelength for a photon of light

Chemistry
1 answer:
MAVERICK [17]2 years ago
6 0

Answer:

6) λ  =  0.84 × 10⁻⁸ m

7) λ  =  0.84 × 10⁻⁶ m

Explanation:

6) Given data:

Wavelength of photon = ?

Frequency of photon = 3.56 × 10¹⁶ Hz

Solution:

Formula:

Speed of radiation = frequency × wavelength

c = speed of wave = 3×10⁸ m/s

by putting values,

3×10⁸ m/s  = 3.56 × 10¹⁶ Hz ×  λ

λ  =  3×10⁸ m/s   / 3.56 × 10¹⁶ s⁻¹

λ  =  0.84 × 10⁻⁸ m

7) Given data:

Wavelength of photon = ?

Frequency of photon = 6.15 × 10¹⁴ Hz

Solution:

Formula:

Speed of radiation = frequency × wavelength

c = speed of wave = 3×10⁸ m/s

by putting values,

3×10⁸ m/s  =  6.15 × 10¹⁴ Hz ×  λ

λ  =  3×10⁸ m/s   /  6.15 × 10¹⁴ Hz s⁻¹

λ  =  0.84 × 10⁻⁶ m

Elements occur in a number of isotopic forms. In this problem, you will learn about the notation used to distinguish different i
alina1380 [7]

Answer:

  • <em>Number of protons, Z = 14</em>
  • <em>Number of neutrons, N = 14</em>

Explanation:

<u>1) About isotopes:</u>

<em>Isotopes</em> are different kind of atoms of the same element. Hence, they have the atomic number (Z), which is the number of <em>protons</em>, the same number of electrons (talking about to neutral atoms, not ions), and different <em>number of neutrons N).</em>

This is, it is the number of neutrons what distinguish different isotopes of an element.

<u>2) About the notation used to distinguish different isotopes:</u>

A superscript and a subscript, both to the left of the chemical symbol of the element, are used to <em>distinguish different isotopes</em>:

       A ←------------- This superscript tells the mass number of the isotope

           X ←--------- This is the chemical symbol of the element

      Z ←-------------- This subscript is the atomic number of isotope

In our case, the notiation for the isotope of silicon is:  ²⁸₁₄ Si

So, we have:

  • 28 is the mass number (A)
  • 14 is the atomic number (Z)
  • Si is the chemical symbol.

Now, you can answer the questions of the <em>part A</em>:

  • Number of protons: Z = 14
  • Number of neutrons N:

       mass number = number of protons + number of neutrons

                   A         =                 Z              +                N

⇒ N = A - Z = 28 - 14 = 14

In <u>conclusion</u>:

  • Number of protons, Z = 14
  • Number of neutrons, N = 14

What is an atomic weight?
S_A_V [24]
The average weight of an atom of an element, formerly based on the weight of one hydrogen atom taken as a unit or on 1/16 (0.0625) the weight of an oxygen atom, but after 1961 based on 1/12 the weight of the carbon-12 atom.

Consider the balanced equation below.
kondaur [170]

The option which gives the correct mole ratios is H₂S : SO₂ = 2 : 2 and O₂ : H₂O = 3 : 2

<h3 /><h3>What is Mole ratio ?</h3>

It is a conversion factor between compounds in a chemical reaction, that is derived from the coefficients of the compounds in a balanced equation

Molar ratio also known as stoichiometry is the ratio in which the reactants and products are either formed or reacted in the given equation

The balanced equation for given reaction is as follows ;

2H₂S + 3O₂ --> 2SO₂ + 2H₂O

Molar ratio can be determined by the coefficients of the compounds in the balanced reaction

Coefficient is the number in front of the chemical compound and they are as follows

  • H₂S - 2
  • O₂ - 3
  • SO₂ - 2
  • H₂O - 2

Therefore, correct option is H₂S : SO₂ = 2 : 2 and O₂ : H₂O = 3 : 2
