6. Draw the unit cell in the pattern at right. Circle the asymmetric unit on the drawing? How many of these features ar...
8. The monoclinic unit cell is shown below including the angles of the cell. How many atoms below exclusively to the unit cell? Is this primitive or non-primitive? Use the angels as a guide the identify the a, b and c edges on the drawing at left. Please show (draw) the two-fold axis and the mirror plane on the model at right. 222 </ 2 w2
5. In the two dimensional unit cells below (a-c) draw the primitive unit cell. Also draw the non- primitive unit cell in (c). Indicate the lattice parameter(s) for each cell. (a) (b) (c)
Shown at the right is a three-dimensional unit cell pattern for a structure of packed spheres. The center of each of eight spheres is at a corner of the cube, and the part of each that lies within the boundaries of the cube is shown. If all of the sphere segments enclosed inside the unit cell boundaries could be glued together, how many whole spheres could be constructed? Which ion of each pair is larger? Hint: How do the sizes...
To introduce you to the concept of the unit cell, draw a square in the diagram below to indicate the unit cell, which is the smallest square that can be used to accurately reproduce the entire al pattern. Draw the square such that each vertex of the square is at the center of a circle. Under the image below, indicate the number of each kind of circle that is in the unit cell that you drew. To introduce you to...
How many total (or composite) atoms are contained in a unit cell of primitive cubic arrangement?
H,0 O PCls 3 NaNH2, CsHioO (Draw the structure) 1. How many asymmetric center's are present in the following structure? a. Number of asymmetric centers present b. Number of stereoisomers possible Circle the meso compounds но" Br Br raw the structure of the reactant and product for the following reactions. If the product can exist tereoisomers, show which stereoisomers are formed. (354S)-3-bromo-4-methylhexane + CH30-
I NEED ANSWERED ASAP!!! First, draw a cell with 6 chromosomes as it moves through the phases of meiosis. Explain what nondisjunction is. Draw and copy a picture of your drawing of your cell with 6 chromosomes to start with as it goes through the phases of meiosis with nondisjunction occurring in one chromosomes pair in meiosis I. Be sure to label the phases and indicate how many chromosomes each resulting cell will have. Label the monosomies vs. trisomies. EXTRA...
draw the structure of 1,2-dimethylcyclopropane. how many asymmetric centers does this compound have? does it have a plane of symmetry, if so draw the plane of symmetry
1. Calculate the density of the magnesium unit cell. HCP has 6 atoms per unit cell for the full HCP structure. The primitive form of the HCP has 2 atoms/unit cell. At. Wt. 24.305g/mole, a 3.29A, c 5.21 A. 2. Calculate the density of the FCC nickel lattice with an interstitial hydrogen in the centered position of the unit cell. You may assume that there is no lattice dilation due to the presence of the hydrogen atom. a 3.524A, At.Wt....
For 1,3-dimethoxycyclohexane: (i) determine how many asymmetric center and stereoisomers there are? (ii) draw the highest and lowest energy conformation for each. (iii) determine which isomer has the lowest potential energy. (iv) number them and indicate which ones are enantiomeric, diastereomeric or meso.
