Heat required in a system can be calculated by multiplying the given mass to the
specific heat capacity of the substance and the temperature difference. It is
expressed as follows:<span>
Heat = mC (T2-T1)
Heat = 10.0 g (4.18 J/g-C ) ( 6.0 C )
<span>Heat = 250.8 J</span></span>
The final step in a typical titration, that is here an acid base one would be to finally find the concentration of your unknown substance whether that be the acid or the base. The other steps are used before this to come to the correct calculation and conclusion.
Answer:
Pyridine
Explanation:
Pyridine is a stronger nucleophile than pyrole ,
Since , both have a lone pair of electron on its nitrogen atom , and both the structure are aromatic in nature .
But , in case of pyrole , the lone pair on nitrogen participates in the delocalization and makes the ring aromatic in nature . hence the lone pair losses its nuleophilic character .
But , in case of pyridine , the lone are free to act as a nucleophile , since they are not involved in the delocalization of the ring .
