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 .
D) Responds slowly
Good luck. It responds slower them the nervous system
Taking into account the Newton's second law, the correct answer is option A. F = 9.68 N right
In first place, acceleration in a body occurs when a force acts on a body.
Newton's second law states that a force will change the speed of an object because the speed and/or direction will change. These changes in velocity are called acceleration.
So, Newton's second law defines the relationship between force and acceleration mathematically. This law says that the acceleration of an object is directly proportional to the sum of all the forces acting on it and inversely proportional to the mass of the object
Mathematically, Newton's second law is expressed as:
F= m×a
where:
- F = Force [N]
- m = Mass [kg]
- a = Acceleration [m/s²]
In this case, you know:
- F= ?
- m= 2.2 kg
- a= 4.4 m/s²
Replacing in Newton's second law:
F= 2.2 kg× 4.4 m/s²
Solving:
<u><em>F= 9.68 N</em></u>
Finally, As the bowl of fruit accelerates to the right, the correct answer is option A. F = 9.68 N right
