<h2>Answer: i agree B</h2><h2>Explanation:</h2>

A the gun wasn't found. this would be an issue but still possible to determine distance with gunpoweder residue

C a hollow point round was used. that is just some type of bullet. i dont remember any specific lesson on bullet identification

D the gun was decades old. this could also be an issue, but it doenst have anything to do with distance

So it must be B. unless the victim could tell you how far the shooter was. but then we would have to consider consciousness, if the victim was facing the shooter, and if the victim was sober. but that's juts overthinking things. it 's most likely B

I would think 2. The victim survived the incident because the victim would have moved or gotten up, which changes the distance between the victim and the gun.

What is the pH of a solution has a hydrogen ion concentration of 6.3 x 10–10 M? Show work
NISA [10]

Answer:

pOH = 4.8

pH = 9.2

Explanation:

Given data:

Hydrogen ion concentration = 6.3×10⁻¹⁰M

pH of solution = ?

pOH of solution = ?

Solution:

Formula:

pH = -log [H⁺]

[H⁺] = Hydrogen ion concentration

We will put the values in formula to calculate the pH.

pH = -log [6.3×10⁻¹⁰]

pH = 9.2

To calculate the pOH:

pH + pOH = 14

We will rearrange this equation.

pOH = 14 - pH

now we will put the values of pH.

pOH = 14 - 9.2

pOH = 4.8
