Answer:
The presence of dust on the victim's right or left hand
Explanation:
The presence of powder, the route of the bullet, and the damage the bullet generates tells us what the caliber of the weapon was like, and type.
The presence of gunpowder in the hand is a consequence of the person being shot, usually in the victim's skilled hand.
37.5 for median ( first organize from least to greatest, elimate from each side until you get to center then add two numbers and divide by two.) Hope that helps.
Acid-base tiltrations has DNA that can help in the process of neutralization. not so sure about it
Answer:
Option B. It is a basic solution.
Explanation:
To know which option is correct, let us calculate the pH of the solution.
First, we shall determine the pOH of the solution. This is illustrated below:
Concentration of Hydroxide ion, [OH¯] = 3.5×10¯⁶
pOH =.?
pOH = –Log [OH¯]
pOH = –Log 3.5×10¯⁶
pOH = 5.5
Finally, we shall determine the pH. This can be obtained as follow:
pOH = 5.5
pH =?
pH + pOH = 14
pH + 5.5 = 14
Collect like terms
pH = 14 – 5.5
pH = 8.5
The pH scale reads as follow:
0 to 6 => Acidic
7 => Neutral
8 to 14 => Basic
Comparing the pH of the solution (i.e 8.5) with the pH scale, we can conclude that the solution is basic because the pH of solution lies between 8 and 14.
