Concept explainers
Interpretation:
The ratio of cations to anions in each given unit cell corresponds to the ratio of cations to anions in the formula of each given compound is to be shown.
Concept introduction: The unit cell is the smallest part of any three-dimensional crystal system. Body centered cubic unit cell is formed when atoms are arranged at all the corners of the cube as well as at the centre of the body. A cube comprises of eight corner atoms.
A body centered cubic unit cell (BCC) comprises one atom at the center of the cubic unit cell other than the corner atoms.
A face centered cubic unit cell (FCC) comprises atoms at the center of each face of the cubic unit cell other than the corner atoms.
Voids are the empty spaces present within the unit cells. Each unit cell comprises of four octahedral and eight tetrahedral voids.
To determine: The representation of the ratio of cations to anions in each unit cell corresponds to the ratio of cations to anions in the formula of each compound.

- e. If (3R,4R)-3,4-dichloro-2,5-dimethylhexane and (3R,4S)-3,4-dichloro-2,5-dimethylhexane are in a solution at the same concentration, would this solution be expected to rotate plane polarized light (that is, be optically active)? Please provide your reasoning for your answer. [If you read this problem carefully, you will not need to draw out the structures to arrive at your answer...]arrow_forward1. How many neighbors does the proton that produces the multiplet below have? 2. 3. اللـ Draw a partial structure from the multiplet below. (The integration of the multiplet is 6) M Using the additivity constants found in appendix G of your lab manual, calculate the approximate chemical shifts of the protons indicated below. (Show your work!!!) B A Br SHarrow_forward1) Suppose 0.1 kg ice at 0°C (273K) is in 0.5kg water at 20°C (293K). What is the change in entropy of the ice as it melts at 0°? To produce the original "water gas" mixture, carbon (in a combustible form known as coke) is reacted with steam: 131.4 kJ + H20(g) + C(s) → CO(g) + H2(g) From this information and the equations in the previous problem, calculate the enthalpy for the combustion or carbon to form carbon dioxide. kindly show me how to solve this long problem.

Composite materials can only be: metal-polymer or polymer-polymer.(B). Composite materials can be made up of particles, but not fibers or sheets.(C). When the reinforcing particles are uniformly distributed in a composite material, there may be a greater tendency for it to have isotropic properties.(D). None of the above is correct.arrow_forwardIf we are talking about viscoelastic modulus or viscoelastic relaxation modulus in polymers, indicate the correct option.(A). It reports the variation of elastic behavior as a function of time.(B). It is only useful for defining its glass transition temperature.(C). It only allows us to define the polymer degradation temperature.(D). Neither option is correct.arrow_forward
