Explanation:
1). The given data is as follows.
, 
C = 5.73 
Hence, calculate the change in enthalpy of the reaction as follows.
= 
= -70.25 KJ
As, number of moles = 
= 
= 0.018 mol
Therefore, enthalpy of reaction in kJ/mol hexane is as follows.
= 
kJ/mol
Thus, we can conclude that 
for the reaction in kJ/mol hexane is kJ/mol
.
2). As we know that,
Number of moles =
= 
= 0.017 mol
= 
= -65.875 kJ
As, 
-65.875 kJ = 
C = 4.56
Hence, heat capacity of the bomb calorimeter is 4.56 .
Hey im happy to help!
Heat can float from one place to another, like all energy.Heat floats in solids by conduction, that happens because the molecules hit one another.Heat within the solid will flow from hot to cold.Heat will flow downward if its cold there.
Hope this helps, have a great rest of your day!
Repulsion is a force or interaction among the atoms in a molecule in which the atoms REPEL one another. By the word itself repulsion, meaning to repel, it automatically bans the idea of ATTRACTION. Therefore, the statement above is FALSE. The answer to this question is "B. False".
Answer:
a.Phenols have the ability to spread out the negative charge that forms.
Explanation:
This happens because of the aromatic ring the phenols have. When loosing the proton, the anion formed have different resonance isomers due to the double bonds in the aromatic ring. This resonance makes the anion more stable and prevents the reaction going backwards.
On the other hand, regular alcohol doesn't have resonace and the reaction of loosing the proton goes leftward and righward: is in equilibrium.
That equilibrium decreases the acidity of the alcohol.
