Hey there! :
1) <span>
Solid Solutions </span>
Solid solutions are formed only by solutes and solid solvents. In
everyday life, the main examples of this type of solution are metallic alloys.
2) Liquid Solutions
Liquid solutions have liquid solvent, usually water, and solutes can be solid, liquid or gaseous.
3) Gaseous solutions
<span>This kind of solution is formed by the only mixture of gases. Air is an
example, as its approximate composition is 78% nitrogen gas, 21% oxygen gas and
1% of other gases.</span>
Answer:
Cis- and trans-3-hexene are symmetric hydrocarons that give only one major product i.e 3-hexanol upon hydroboration.
Explanation:
During hydroboration of 3-hexene, borane (BH3) is added to the double bond of hexene, that transfers the hydrogen atoms to that carbon which becomes is bonded to the boron. The process of hydroboration is created in two steps that leads to the formation of 3-hexanol and boric acid. (please see figure)
Now, the two stereoisomers, Cis- and trans-3-hexene both will give off the 3-hexanol upon hydroboration and the structure of these are illustrated in the figure.
<span>work = force x distances </span>
<span>A - moving 2 newton's up 0.6 meter = 1.2 joules
B - moving 4 newton's up 0.6 meter = 2.4 joules
C - moving 6 newton's up 0.3 meter = 1.8 joules
D - moving 9 newton's up 0.3 meter = 2.7 joules
The greatest amount of work is in example D.
