Bloodstain Pattern Analysis (BPA), one of several specialties in the field of forensic science, involves the study and analysis of bloodstains at a known or suspected violent crime scene with the goal of helping investigators draw conclusions about the nature, timing and other details of the crime.

The use of bloodstains as evidence is not new; however, new experts have claimed to be able to use fluid dynamics, physics, and other calculations to determine with accuracy previous events at a crime scene. For example, the shape of blood droplets might be used to draw conclusions as to how far away the victim was from a gun when they were shot.

This technique of forensic science has drawn more skeptical scrutiny since 2000; large amounts of the body of work in BPA is done by crime investigators using subjective hunches rather than scientists from other disciplines. A report released by The National Academy of Sciences in 2009 highlighted several incidents of blood spatter analysts to overstate their qualifications as well as questioned the reliability of their methods in the courtroom.

draw the lewis structure, including unshared pairs, of the following molecule. carbon has four bonds in the compound. propane (c
SIZIF [17.4K]

There are three carbon and 8 hydrogen present in propane molecule. The Lewis structure of propane is shown as:

Three molecules of such carbon atoms bound to eight molecules with hydrogen atoms make up the organic complex propane molecule.

It is known that carbon has 4 valence electrons and hydrogen has one valence electron. Carbon needs 4 extra electrons to complete its octet hence, it will share its electrons with with 4 hydrogen atom and complete its octet.

Carbon will be formed 4 bond . Three bond with hydrogen and one bond with carbon atom.

To know more about Lewis structure.

Identify the substances that will appear in the equilibrium constant expression for the equation: 2Ag+(aq)+Zn(s)<->Zn2+(aq
Simora [160]

Hey there!


We Know that:



 2 Ag⁺(aq) + Zn(s) <-> Zn²⁺(aq)+2 Ag(s)


The equilibrium expression for the reaction is:



Kc =  [ Zn⁺² ]  /  [Ag⁺ ]²


Hope that helps!
