No it doesnt have any....
Rafters are usually on 2 ft. centers.
Yes, it does.
12' is max for a 2 x 4 wall. You will need 69 studs for a 90' wall with 16" centers.

home improvement centers have floor scrapers they will rent to you. they are a heavy machine with two wheels and a vibrating blade in front that you walk behind, great for pulling up tile, carpet, linoleum, etc. . .
Yes, chiral centers do not have to be carbon atoms. Any atom that is bonded to four different groups can be a chiral center.
No, nifedipine does not have any chiral centers. It is a racemic mixture of two enantiomers, meaning it does not have stereoisomers that are non-superimposable mirror images of each other.
An amino acid can have a maximum of two chiral centers, but they do not all have two chiral centers. For example, threonine and isoleucine are amino acids that have two chiral centers.
Sucrose does not have any chiral centers because it is composed of two monosaccharides, glucose, and fructose, which are both not chiral in the specific form found in sucrose.
Betamethasone has three chiral centers.
Streptomycin has four chiral centers.
24-heptadiene has two chiral centers. Chiral centers are carbons that have four different substituents attached, leading to non-superimposable mirror image structures.
To identify chiral centers in ring structures, look for carbon atoms that are bonded to four different groups. These carbon atoms are chiral centers and can create stereoisomers.
For a molecule with 2 chiral centers, there are 4 possible stereoisomers.
To determine chiral centers in a molecule, look for carbon atoms bonded to four different groups. These carbon atoms are chiral centers, meaning they have non-superimposable mirror images.
For chiral compounds, the number of possible isomers depends on the number of chiral centers in the molecule. The maximum number of stereoisomers that can be formed for a molecule with n chiral centers is 2^n.
For a molecule with n chiral centers, there are a possible 2^n isomers that can be formed.
