Answer:
(3R,4R)-4-bromohexan-3-ol
Explanation:
In this case, we have reaction called <u>halohydrin formation</u>. This is a <u>markovnikov reaction</u> with <u>anti configuration</u>. Therefore the halogen in this case "Br" and the "OH" must have <u>different configurations</u>. Additionally, in this molecule both carbons have the <u>same substitution</u>, so the "OH" can go in any carbon.
Finally, in the product we will have <u>chiral carbons</u>, so we have to find the absolute configuration for each carbon. On carbon 3 we will have an "R" configuration on carbon 4 we will have also an "R" configuration. (See figure 1)
I hope it helps!
Explanation:
When iodine heptafluoride reacts rapidly with water to give a mixture of periodic acid and hydrofluoric acid. Reaction equation for the same is as follows.
As it is given that there are 
moles of iodine heptafluoride are present. Molar mass of 
is 259.9 g/mol. Molar mass of 
is 227.94 g/mol and molar mass of HF is 20.01 g/mol.
Now, according to the reaction equation M gives M 
.
Also, the volume is given as 795 ml or 0.795 L (as 1 mL = 0.001 L).
Hence, calculate the concentration of into the solution as follows.
Concentration = 
= 
= 
mol/L
or, = 0.047 M
Now, as 1 mol of produces 7 mol HF. So, 
M HF.
Therefore, concentration of HF will be calculated as follows.
Concentration of HF = 
= 0.33 M
Thus, we can conclude that concentration of periodic acid is 0.047 M and concentration of hydrofluoric acid is 0.33 M.
Answer:
When atoms approach one another closely, the electron clouds interact with each other and with the nuclei. If this interaction is such that the total energy of the system is lowered, then the atoms bond together to form a molecule.
Explanation:
Hydrophilic molecules that are to be released by cells are stored in membrane-bound structures called <u>Secretory vesicles.</u>
<u></u>
The head, which forms the outer and inner lining, is 'hydrophilic' (water-loving), while the tail facing the interior of the cell membrane is 'hydrophobic' (water-hating).
All lipid molecules in cell membranes are amphiphilic (or amphipathic). That is, they have a hydrophilic (“water-loving”) or polar end and a hydrophobic (“hydrophobic”) or non-polar end.
Cells contain membrane-bound structures called cellular organelles and more complex chemicals. Organelles are sometimes referred to as subunits within cells designed to perform specific functions.
Channel-forming proteins can be used to facilitate the transport of water and other hydrophilic molecules. These channels are often gated to regulate transport rates. In facilitated transport, a hydrophilic molecule binds to a 'carrier' protein. This is a form of passive transport.

KE = 1/2mass • velocity^2
So, if we take half of 55, we get 27.5
Next, we take 2, and square it, getting 4.
Lastly, take 27.5, and multiply it by 4, getting 110 Joules, hope this helps and have a great day!
