If two fatty acids, glycerol, and a phosphate group undergo a dehydration reaction, what molecule forms
GrogVix [38]
<h3>Answer:</h3>

            A Phospholipid is formed.

<h3>Explanation:</h3>

                   The reaction of fatty acids, glycerol and phosphoric acid is given below. In this reaction the carboxylic groups of fatty acids and the hydrogyl groups of glycerol undergo an Esterification Reaction with the elimination of two water molecules and formation of Ester functional group. Also, the third hydroxyl group of glycerol undergo dehydration reaction with phosphoric acid. The resulting molecule is known as phospholipid.

                    Biologically, Phospholipids are found in the cell membranes. The long hydrocarbon chains of fatty acids acts as hydrophobic (water fearing) tails and the phosphate group acts as hydrophilic (water loving) head. They form a barrier protecting the internal environment of cell from external surrounding.

The light produced by the electron in strontium has a wavelength of 608 nm. How much energy must be added to strontium to get it
liq [111]

According to Einstein the energy of photon is given by the equation,

E = hν = h . c/λ

where h is Planck's constant, c is the speed of light, ν is the frequency of light and λ is the wavelength of light.  

Given, wavelength = 608 nm = 608 x 10⁻⁹ m  

Conversion factor: 1 nm = 10⁻⁹ m  

c = 3 x 10⁸ m/s

h = 6.626× 10⁻³⁴ J.s

Substituting the data into the equation we get,  

E = h . c/λ

E = 6.626× 10⁻³⁴ J.s x (3 x 10⁸ m/s) / 608 x 10⁻⁹ m  

E =  3.27 x 10⁻¹⁹J

3.27 x 10⁻¹⁹J  energy must be added to strontium to get it to produce 608 nm wavelength.

a concentrated solution of sulfuric acid, H2SO4, has a concentration of 18.0 M. How many mL of the concentrated acid would be re
valkas [14]

Answer: A 13.88 mL of the concentrated acid would be required to make 250. mL of a 1.00 M H_{2}SO_{4} solution.

Explanation:

Given: M_{1} = 18.0 M,     V_{1} = ?

M_{2} = 1.00 M,         V_{2} = 250 mL

Formula used to calculate the volume of concentrated acid is as follows.

M_{1}V_{1} = M_{2}V_{2}

Substitute the values into above formula as follows.

M_{1}V_{1} = M_{2}V_{2}\\18.0 M \times V_{1} = 1.00 M \times 250 mL\\V_{1} = \frac{1.00 M \times 250 mL}{18.0 M}\\= 13.88 mL

Thus, we can conclude that 13.88 mL of the concentrated acid would be required to make 250. mL of a 1.00 M H_{2}SO_{4} solution.

The two products that are formed when a solution of HNO3 and a solution of NaOH react are water and?
Naily [24]

Answer:

NaNO3

Explanation:

Hello,

In this case, the required reaction is an acid-base neutralization reaction which is said to be:

HNO_3+NaOH\rightarrow NaNO_3+H_2O

There, we see that the sodium displaced the hydrogen in the nitric acid to form sodium nitrate a very used salt in the industry, so, as a result of that displacement, water is formed as the secondary neutralization product. For the above mentioned, answer is NaNO3 .

Best regards.
