Why are some fatty acids called saturated?

Chemistry
1 answer:
Len [333]3 years ago
4 0
Fats (triglycerides) that contain palmitic acid and stearic acid are therefore known as saturated fats. Fats made up of saturated fatty acids are solid at room temperature. ... Because it is polyunsaturated, it is liquid at room temperature.

brilliants [131]

Answer:

  •           ^{35}_{16}S

Explanation:

When the nucleus of an <em>atom captures and electron</em>, such electron combines with a proton and forms a neutron. Thus, the mass number remains the same (just a proton has been converted into a neutron) but the atomic number (the number of protons) decrease in one.

Then, the daughter nuclide will have the same mass number and the atomic number reduced in one.

The given parent isotope is    ^{35}_{17}Cl,    which means that it has these features:

  • Chemical symbol: Cl
  • Name of the element: chlorine
  •  Mass number (the superscript to the left): 35
  •  Atomic number (the subscript to the left): 17

And the daughter nuclide after the electron capture will be:

  • Mass number: 35 (the same of the parent nuclide)
  • Atomic number: 17 - 1 = 16
  • Identity: sulfur (search the element with atomic number 16 in a periodic table).
  • Chemical symbol: S

  • Idenity of the daughter nuclide using the isotope notation:

          ^{35}_{16}S

Hence, the answer is the third choice.

What is the mass of 1.75 moles of HF?
olganol [36]

Answer:

Mass = 35.02 g

Explanation:

Given data:

Number of moles = 1.75 mol

Mass of HF = ?

Solution:

Formula:

Mass = number of moles × molar mass

Molar mass of HF = 20.01 g/mol

by putting values,

Mass = 1.75 mol × 20.01 g/mol

Mass = 35.02 g

Which layer of the atmosphere is between the exosphere and the mesosphere
Olenka [21]

The atmosphere of earth is made of five main layers.

1) Troposphere : This is the lowest part of the atmosphere. Most of the air that makes up the atmosphere is present in this layer.

2) Stratosphere : This layer is present above troposphere and extends up to 50 km. It contains ozone layer which prevents the harmful ultraviolet rays from the sun from entering the lower troposphere

3) Mesosphere : The layer above stratosphere is known as mesosphere.

4) Thermosphere : The region lies above mesosphere.

5) Exosphere : The is the outermost region of the atmosphere.

From the above discussion we can see that the layer that lies between exosphere and mesosphere is Thermosphere

Describe the properties of alkali metals. based on their electronic arrangement, explain whether they exist alone in nature.
saul85 [17]

The alkali metals can't exist alone in nature because of incomplete outermost shell of alkali metals.

<h3>What are the  properties of alkali metals?</h3>

The alkali metals have the high thermal and electrical conductivity. It has high lustre, ductility, and malleability as compared to other materials. Each alkali metal atom has one electron in its outermost shell which make more reactive.

So we can conclude that the alkali metals can't exist alone in nature because of incomplete outermost shell of alkali metals.
