Answer:

When an investigator processes and reconstructs a crime scene where shots were fired, determining who may have shot the firearm may be critical to the case. The lab may be able to assist with such investigations through the use of gunshot residue (GSR) analysis. GSR is typically expelled from a firearm upon discharge and can land on individuals in close range of the firearm. GSR kits are designed to collect these particles, and the Trace evidence section of the lab has the equipment and expertise to analyze these kits. While GSR testing can provide important information for your case, there are limitations in what the results indicate in a shooting incident.

Rutherford’s gold foil experiment gave evidence that an atom is mostly empty space. true false
Sholpan [36]

The given statement is true .

<h3>What is Rutherford’s gold foil  experiment?</h3>
  • A piece of gold foil was hit with alpha particles, which have a favorable charge. Most alpha particles went right around. This showed that the gold particles were mostly space.
  • The Rutherford gold leaf investigation supposed that most (99%) of all the mass of an atom is in the middle of the atom, that the nucleus is very small (105 times small than the length of the atom) and that is positively captured.
  • For the distribution experiment, Rutherford enjoyed a metal sheet that could be as thin as practicable. Gold is the most malleable of all known metals. It can easily be converted into very thin sheets. Hence, Rutherford established a gold foil for his alpha-ray scattering experimentation.

What elements are in NaC2HO4 and how many atoms are in each element​
JulijaS [17]

Answer:

Each molecule contains one atom of A and one atom of B. The reaction does not use all of the atoms to form compounds.

                 A + B ⟶ Product

Particles: 6      8              6

If six A atoms form six product molecules, each molecule can contain only one A atom.

The formula of the product is ABₙ.

If n = 1, we need six atoms of B.

If n = 2, we need 12 atoms of B. However, we have only eight atoms of B, so the formula of the product must be AB.

Thus, 6A + 6B ⟶ 6AB, with two B atoms left over.
