Answer:
The dependent variable: population of birds
Explanation:
Its D because Dependent means what were collecting data of and we know we need to collect data from the population of birds.
Hope this helps :3
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
.
we need the three measurements to be able to asses significant figures.
