The compound alanine has an S configuration based on the Fisher projection of the compound.
<h3>What is Fisher projection?</h3>
We know that the stereochemistry of a compound is very important in the study of organic chemistry. When we talk about the stereochemistry, we are talking about the way and manner in which the atoms that are found in the compound are arranged.
The configuration of the compound can be obtained when we look at the image of the fisher projection formula of the compound. There are two main configurations that the compound could have have. These are the R and S configurations.
The configuration would be assigned to the compound on the basis of the relative positions of the priority groups in the compound. We can see that in the fisher projection formula of alanine, the priority groups are assigned from left to right thus it has an S configuration.

Answer:
For (a) the independent variable is what stays constant throughout the whole experiment and the dependent variable is changes in the experiment.
Explanation:
I'm not sure about the other parts, but I hope my explanation for a can get you started :)
We have:
V = 55.0 gallons x 3.78541 = 208 L
P = 16500 kPa
T = 23 + 273.15 = 296.15 K
Part A) From the equation PV =
we get:
mass of O₂ = (16500 kPa x 208 L x 32 g/mol) / (8.314 x 296.15 K)
= 44.6 Kg
Part B) at STP we have:
T = 273.15 K and P = 101.3 kPa
so from PV = mRT / M
V = (44600 x 8.314 x 273.15) / (32 x 101.3)
= 31248 L
Part C) From the equation PV = mRT / M
we get
T = (150 atm x 101.3 kPa / atm x 208L x 32g/mol) / (8.314 x 44600)
= 272.8 K
Part D) we have:
T = 24 + 273.15 K = 297.15 K
so from PV = mRT / M, we get
P = (44600 x 8.314 x 297.15) / (32 x 55)
= 62464 kPa
<span>The solid lines between N and Mg are actually ionic bonds. N has 5 valence electrons (2 of which are paired). Of the 3 that are unpaired, 2 are part of covalent bonds with adjacent carbon atoms. N accepts an extra electron to complete its octet, but gets a formal charge of -1. This allows for formation of an ionic bond with Mg, which is +2. Two of these charged N atoms therefore neutralize the charge of the central Mg. As for the coordinate (dative) covalent bonds, Mg has empty orbitals - the ionic bonds with the charged N atoms give it only 4/8 possible valence electrons.
The other two N atoms (dotted lines) have a formal charge of 0 since they form three covalent bonds with adjacent carbon atoms, but they still have a lone pair. Therefore, just to improve stability, each of these N atoms can "donate" its lone pair to Mg in order to complete its octet.
I hope my answer has come to your help. Thank you for posting your question here in Brainly. We hope to answer more of your questions and inquiries soon. Have a nice day ahead!
