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.
To determine the number of studs needed for a 60-foot wall at 16-inch centers, first convert the wall length to inches: 60 feet x 12 inches/foot = 720 inches. Then, divide the total length by the spacing: 720 inches / 16 inches = 45 studs. Since you need one additional stud for the end of the wall, you will need a total of 46 studs.

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.
I think glucose has 4 chiral centres four carbon atoms has four different compound/elements bonded to it.
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.
Streptomycin has four chiral centers.
Betamethasone has three 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.
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.
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 a molecule with n chiral centers, there are a possible 2^n isomers that can be formed.
