Umnica [9.8K]2 years ago
6 0

Answer:

Either of the three colors

Violet , indigo , Blue

Explanation:

The different ranges of color produced as per the electromagnetic spectrum are as follows  

• Violet:   400 - 420 nm

• Indigo:   420 - 440 nm

• Blue:   440 - 490 nm

• Green:   490 - 570 nm

• Yellow:   570 - 585 nm

• Orange:   585 - 620 nm

• Red:   620 - 780 nm

A material absorbing light in the range of 400-500 nm can have three colors –  

•  Violet:   400 - 420 nm

• Indigo:   420 - 440 nm

• Blue:   440 - 490 nm

(4) Calculate the % of a compound that can be removed from liquid phase 1 by using ONE to FOUR extractions with a liquid phase 2
maksim [4K]

Answer:

One extraction: 50%

Two extractions: 75%

Three extractions: 87.5%

Four extractions: 93.75%

Explanation:

The following equation relates the fraction q of the compound left in volume V₁ of phase 1 that is extracted n times with volume V₂.

qⁿ = (V₁/(V₁ + KV₂))ⁿ

We also know that V₂ = 1/2(V₁) and K = 2, so these expressions can be substituted into the above equation:

qⁿ = (V₁/(V₁ + 2(1/2V₁))ⁿ = (V₁/(V₁ + V₁))ⁿ =  (V₁/(2V₁))ⁿ = (1/2)ⁿ

When n = 1, q = 1/2, so the fraction removed from phase 1 is also 1/2, or 50%.

When n = 2, q = (1/2)² = 1/4, so the fraction removed from phase 1 is (1 - 1/4) = 3/4 or 75%.

When n = 3, q = (1/2)³ = 1/8, so the fraction removed from phase 1 is (1 - 1/8) = 7/8 or 87.5%.

When n = 4, q = (1/2)⁴ = 1/16, so the fraction removed from phase 1 is (1 - 1/16) = 15/16 or 93.75%.

5.1169 mol of Ne is held at 0.9148 atm and 911 K. What is the volume of its container in liters?
sveticcg [70]

By applying the Boyle's equation and substituting our given data the volume of the container was found to be 418.14 Litres

<h3>Boyle's  Law</h3>

Given Data

  • number of moles of Ne = 5.1169 mol
  • Pressure = 0.9148 atm
  • Temperature = 911 K

We know that the relationship between pressure and temperature is given as

PV = nRT

R = 0.08206

Making the volume subject of formula we have

V= nRT/P

Substituting our given data to find the volume we have

V = 5.1169*0.08206*911/0.9148

V = 382.522353554/0.9148

V = 418.14 L

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.
