The element that was oxidized is carbon, as it’s oxidation state increased (electrons were lost) from +2 (in the reactants) to +4 (in the products). The element that was reduced is nitrogen, as it gained electrons and went from a +2 oxidation state (reactants) to a 0 oxidation state (products). Since the carbon was oxidized and it’s electrons were used to reduce the nitrogen, carbon is the reducing agent.
There are zero number of methylene groups in the substance 2,4-dimethylhexane. Methylene groups are the part of a molecule that contains a carbon atom that has a double bond or =CH. Looking at the structure of 2,4-dimethylhexane, you cannot see any carbon atom that has a double bond.
The earth is made up with three different layers
Explanation:
The given data is as follows.
= 50 ml, 
= 345 K
= 298 K, 
= 317 K,
= 50 ml
Now, we will calculate the heat energy as follows.
= 
= 5857.6 J
= 
= 3974.8 J
As, 
so there will be loss of heat. And, some heat will go to the calorimeter.
Hence, 
= 1882.8 J
We assume that the temperature of (calorimeter + water) is 298 K. Hence,
dT = 
= (317 - 298) K
= 19 K
Hence, we will calculate the specific heat as follows.
C = 
= 
= 99.1 J/K
Thus, we can conclude that the value of 
for the calorimeter is 99.1 J/K.
