Which technique was used to detect blood in lisa kinsey's house?

The Luminol Technique

Explanation:

Luminol is a chemical containing carbon, nitrogen, oxygen and hydrogen. It is used by crime scene investigators to detect blood at crime scenes where no blood is visible. The chemical glows greenish-blue when it comes into contact with blood by reacting to hemoglobin, an oxygen-carrying protein in red-blood cells.

answer; ///i believe the correct answer is (aids) acquired immune deficiency syndrome;

the relative atomic mass of an element is the mass of one atom of that element, relative to 1/12th of the mass of a  1212c atom. to convert to an absolute mass in kg, it is necessary to multiply by  1.661×10−271.661×10−27.

the relative atomic mass is roughly equal to the number of neutrons, plus the number of protons, in the nucleus of the atom.

for elements with more than one stable isotope (different types of nucleus with different numbers of neutrons but the same number of protons), the quoted mass is usually the average mass, weighted by the relative abundance of the different isotopes.
