Answer:
rotten egg smell
Explanation:
1,5-pentanedithiol ( C₅H₁₂S ) -
The compound have thiol as the functional group , and hence will show some characteristics of thiol group ,
The thiol group is a -SH group , they are also called mercaptan functional group .
The thiol group has a strong characteristic smell of rotten egg .
And hence , the compound 1,5-pentanedithiol ( C₅H₁₂S ) can easily be distinguished by its rotten egg smell .
Answer:
C. 2.0 mL
Explanation:
This value is due to the fact that the burettes are instruments that allow accurately measure volumes of liquids, in this case it has a precision of ±0.01 mL, which indicates that this is the smallest value that the burette can measure with accuracy, which indicates that 2 mL can be measured accurately without any problem.
Quarts of pure antifreeze must be added to 5 quarts of a 20 antifreeze solution to obtain a 50 antifreeze solution is 3.
Antifreeze solution is a solute that lowers the freezing point of the liquid in a solution.
For calculating the amount of quarts of pure antifreeze solution added can be given by:
5×20/100 + x × 100% = (x+5) × 50/100
Where, x is the amount of antifreeze required for addition and pure antifreeze is 100% of the antifreeze taken.
1 + x = (x+5) 0.5
1 + x = 0.5x + 2.5
0.5x = 1.5
x = 3
So, 3 quarts of pure antifreeze must be added to 5 quarts of a 20 antifreeze solution to obtain a 50 antifreeze solution.
