What is the wavelength of radiation that has a frequency
White raven [17]

Answer:

\lambda = \frac{c}{\nu}

Explanation:

The wavelenght of  a radiation is inversely proportional to its frequency. It can be estimated by the following formula:

\lambda = \frac{c}{\nu}

Where:

  • \lambda is the wavelenght
  • \nu is the frequency
  • c is the speed of light (arroung 300000 km/s)

What kind of chemical bond is formed between nonmetals? Explain your answer.
REY [17]

Answer:

The ionic bond is formed due to an electrostatic force of attraction between two oppositely charged ions. This bond is usually formed between a metal and a nonmetal. Prior to the electrostatic attraction, there is a total transfer of valence electrons from one atom to the other atom.

A steel cylinder of oxygen is being store in a room at 25.0 °C under a pressure of 1250 atm. What pressure would be exerted by t
Rudik [331]

Answer:

P₂ = 1312.88 atm

Explanation:

Given data:

Initial temperature = 25°C

Initial pressure = 1250 atm

Final temperature = 40°C

Final pressure = ?

Solution:

Initial temperature = 25°C (25+273.15 = 298.15 K)

Final temperature = 40°C ( 40+273.15 = 313.15 k)

The pressure of given amount of a gas is directly proportional to its temperature at constant volume and number of moles.

Mathematical relationship:

P₁/T₁ = P₂/T₂

Now we will put the values in formula:

1250 atm / 298.15 K = P₂/313.15 K

P₂ = 1250 atm × 313.15 K / 298.15 K

P₂ = 391437.5 atm. K /298.15 K

P₂ = 1312.88 atm

Give all possible ml values for orbitals that have each of the following:<br> (a) l = 3;
Angelina_Jolie [31]

At l = 3, ml =+3,+2,+1,0,-1,-2,-3

What are quantum numbers?

  • Quantum numbers are used to describe where around a nucleus a particular electron can be found.
  • In any given atom, each electron can be described by four quantum numbers.
  • These are n,l,m1,ms
  • The values that each number can be are based on a set of rules.

What is a magnetic quantum number ?

  • It describes the orientation of the orbitals.
  • It is represented as ml.
  • The value of this quantum number ranges from (-l to +l).
  • When l = 2, the value of  will be -2, -1, 0, +1, +2.
