Answer: C). The scientist made an identification.

Explanation:

Forensic science deals with the searching, identification, collection and analysis of the evidences found at the crime scene or those which are related to the crime.

In an analysis of evidences the identification, quantification, and comparison of the evidences obtained from the crime scene with those which are requested from the suspects or victims takes place.

In the given situation, the scientist will identify the concentration of drug in the blood after the process of analysis of the blood.

AVprozaik [17]

Answer:

D. The electron-withdrawing fluorine atoms pull electron density from the oxygen in trifluoroacetate. The negative charge is more stabilized in trifluoroacetate by this effect.

Explanation:

The structures of trifluoroacetate and acetic acid are both shown in the image attached.

The trifluoroacetate anion (CF3CO2-), just like the acetate anion has in the middle, two oxygen atoms.

However, in the trifluoroacetate anion, there are also three electronegative fluorine atoms attached to the nearby carbon atom attached to the carbonyl, and these pull some electron density through the sigma bonding network away from the oxygen atoms, thereby spreading out the negative charge further. This effect, called the "inductive effect" stabilizes the anion formed,the trifouoroacetate anion is thus more stabilized than the acetate anion.

Hence, trifluoroacetic acid is a stronger acid than acetic acid, having a pKa of -0.18.

The mean radius of the Earth is 6,371 km, and 70.8% of its surface is covered by water. What is the surface area of the Earth co
Marina CMI [18]

Answer:

147,558,601 sqkm

Explanation:

The earth is spherical in shape;

area of sphere = 4πr²

if 70.8% is covered by water then 100-70.8 will be land,

= 29.2%

area occupied by land = (29.2/100) * 4πr²

                                = 0.292*4*3.142*(6371)²

                        =147,558,601 sqkm
