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.
Answer: The object's mass, height off the ground, and the strength of gravity :)
<span>If you overshoot the endpoint in titration of the KHP, an error will happen in your calculations for the molarity of NaOH you are standardizing. For this, a neutralzation reaction happens where amount of acid should be equal to amount of base. Adding more of the base needed to reach the equivalence would mean you have higher volume which will make the calculated concentration of NaOH lesser.</span>
The mass of sulfur in the sample is 0.31g
To calculate mass of sulfur in sample: given that amount galena is 2.34g and mass of lead is 2.03 g as galena contain both lead and sulfur the mass of sulfur = mass of galena- mass of lead , that is, 2.34- 2.03=0.31g.The molecular mass is a algebraic sum of atomic mass of each element in the compound thus the mass of the compound can be obtained by adding atomic of each element. Lead(II) sulphide occurs naturally as the mineral galena, often known as lead glance (PbS). It is a significant source of silver and the most significant lead ore.
