Answer:
The forensic laboratory system in the United States consists of private and public labs. One well-known public lab is the FBI (the Federal Bureau of Investigation) Public labs are mostly run by police officers and state employees, while private labs are organized as a fee-for-service and they are small with a few large and medium=sized operations.
Explanation:
Idk and it's not even 100 points but I hope this helps.
The answer is C.
Electrostatic force binds the the negatively charged to the positive charge atomic nucleus
Answer:
Antimony, it increases as it goes across a period and decreases as it goes down a group. Does potassium or lithium have the smaller atomic radius? Lithium, because as you move across a period it gets weaker and down a group, it gets stronger.
Absorbance is related to the concentration of a substance using the Beer-Lambert's Law. According to this law, absorbance is linearly related to concentration. However, this is only true up to a certain concentration depending on the substance. For this case, we assume that the said law is applicable.
A = kC
Using the first conditions, ewe solve for k.
0.26 = k (0.10)
k = 2.6
A = kC
A = 2.6 (0.20) = 0.52
Therefore, the absorbance at a concentration of 0.20 M and wavelength of 500nm is 0.52.
