If an atom has an electron in the n = 4 state with ml = 2, what are the possible values of l?

Chemistry

Pavel [41]2 years ago
4 0

Answer:

The possible values of l are 2 and 3

Explanation:

Each electrons have four quantum numbers:

  • n: the principal quantum number, which value matches with the energy level of the electron.
  • l: the secondary quantum number, which value can be from 0 to n-1
  • m: the magnetic number, which value can be from -l to l
  • sp: the spin number which value can be -1/2 or +1/2

In this case, n=4 so the values of l are:

l=0, 1, 2, 3

Now, if:

  • l=0 the value of m is m=0
  • l=1 the values of m are m= -1, 0, 1
  • l=2 the values of m are m= -2, -1, 0, 1, 2
  • l=3 the values of m are m= -3, -2, -1, 0, 1, 2, 3

Being all that said, l can be either  equal to 2 or 3

What type of bond connects the fatty acid?
scoray [572]

The  type of bond connects the fatty acid will be " an ester bond".

Fatty acids could be joined to each of the three carbons of the glycerol molecule in a fat molecule by an ester bond that passes through into the oxygen atom. Three molecules are emitted during the establishment of the ester bond. Fats were also known as triacylglycerols as well as triglycerides because they are made consisting of three fatty acids and glycerol.

The three major nutrients in a diet may be carbohydrates, proteins, and fats. According to how many hydrogen bonds they contain, fats are classified as either saturated as well as unsaturated.

The  type of bond connects the fatty acid will be " an ester bond".

Hence, the correct answer will be option (c)

1. A 24.50 g piece of metal displaces 2.6 ml of water. Calculate the density of the<br><br> metal?
PSYCHO15rus [73]

Answer:

9.42g/cm3

Explanation:

Data obtained from the question include the following:

Mass of the metal = 24.50g

Volume of metal = 2.6 ml = 2.6cm3

Density =..?

The density of a substance is defined by the mass of the substance per unit volume of the substance. It is represented mathematically as:

Density = Mass /volume

With the above formula, we can obtain the density of the metal as follow:

Density = Mass/volume

Density = 24.50g/2.6cm3

Density = 9.42g/cm3
