Bogdan [553]4 years ago
4 0

Answer:

c. Three fatty acid chains and a 'backbone' of glycerol

Explanation:

A triglyceride is ester which is derived from glycerol and three (may be different or same) fatty acids. The name is thus derived as tri ( 3 fatty acids) - and glyceride (glycerol backbone). Triglycerides are main constituents of the body fat in human body and other vertebrates.

<u>Triglycerides are the tri-esters which consist of glycerol attached to 3 molecules of fatty acid.</u> Alcohols consists of hydroxyl group. Organic acids consists of carboxyl group. Alcohols and organic acids join to form esters. <u>The molecule of glycerol has 3 hydroxyl groups which are bonded to three fatty acid molecules via ester bonds.</u>

One of the pieces of evidence supporting energy quantization was the line spectra of elements. Why does this demonstrate energy
bezimeni [28]

Answer:

c) There are sharp emission lines demonstrating discrete energy levels.

Explanation:

When an element emits energy in the form of radiation, it produces a spectrum of colors on a photographic plate. This spectrum can either be continuous or discrete. In continuous spectrum the spectrum continues without any discrimination between two regions. This represents the continuous emission of radiation, and thus the continuous emission of energy without any break.

On the other hand, the line spectrum consists of discrete and sharp lines, which shows the emission of radiation in a certain amount in a certain time, with a break between emission. Hence, the line spectra supports the quantization of energy.

The correct option is:

<u>c) There are sharp emission lines demonstrating discrete energy levels.</u>

Does the size of an object<br> affect its rate of fall?
Vitek1552 [10]

Answer:

The acceleration of the object equals the gravitational acceleration. The mass, size, and shape of the object are not a factor in describing the motion of the object. So all objects, regardless of size or shape or weight, free fall with the same acceleration

How many miles are in 8.73 *10^25 atoms of boron
Mnenie [13.5K]

The correct question is: How many moles are in 8.73 \times 10^{25} atoms of boron.

Answer: There are 145 moles present in 8.73 \times 10^{25} atoms of boron.

Explanation:

According to the mole concept, there are 6.022 \times 10^{23} atoms present in one mole of every substance.

Hence, number of moles present in 8.73 \times 10^{25} atoms is calculated as follows.

Moles = \frac{8.73 \times 10^{25}}{6.022 \times 10^{23}}\\= 1.45 \times 10^{2}\\= 145 mol

Thus, we can conclude that there are 145 moles present in 8.73 \times 10^{25} atoms of boron.
