Answer:
8
Explanation:
u can find it on ur chemistry book
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.
Answer:
A forensic palynologist is a spore and pollen expert that helps solve crimes.
The case that Mildenhall worked on was about a murder that involved a prostitute. The police couldn’t find a trace to help solve the case, so they called Mildenhall to help with pollen clues. He was able to find trace evidence in the pollen, which helped police connect the victim to a gang hangout by the crime scene.
A forensic palynologist can help with a criminal investigation by comparing pollen from the suspect and the victim using a comparison microscope to determine if the pollen matches.
The challenges of using a forensic palynologist in a criminal investigation are that judges and juries may have a hard time understanding palynologists.
