Which of these tasks falls under the responsibility of a forensic scientist?

Varvara68 [4.7K]

Answer:

Training officers in how to properly collect evidence

Explanation:

Forensic science is an interesting branch of science that involves the use of scientific procedures to solve a crime case. It encompasses collection of physical evidence from the crime scene and analyzing it in a laboratory using scientific means.

A forensic scientist is the individual in charge of performing these scientific procedures. His/her major role is to run the scientific analysis of the physical evidence brought in by the officers, however, he/she can also perform the task of training officers in how to properly collect evidence, in order not to damage the evidence or render it invalid for use.

A student went to the dentist and found out that he had a cavity. He always brushes his teeth twice a day, so he didn't understa

Free_Kalibri [48]

Answer:

The drinks that the student should avoid - if he wants to avoid damage to his teeth - are drinks C and E, since they are acidic, according to their pH.

Explanation:

pH measures the acidity or alkalinity of a solution, taking into account the amount of hydrogen ions present in it, and established on a scale that goes from 0 to 14.

In chemistry, pH is derived from the formula that indicates:

<em>pH = - Log₁₀ αH⁺</em> , where α is the activity of hydrogen ions.

A solution with a pH of 7 is considered neutral, above this value it is an acidic solution and below this value it is called acidic.

According to this:

<em>Acidic drinks are: drink C (5.3) and E (2.4).</em>
<em>The basic drinks are: drink A (11.9) and drink D (9.8).</em>
<em>The neutral drink is the drink B (7), which corresponds to water.</em>

How many liters of bromine are needed to produce 12 miles of aluminum bromide?

VikaD [51]

Answer:

0.929L of Br2

Explanation:

We'll begin by writing the balanced equation for the reaction. This is given below:

2Al + 3Br2 —> 2AlBr3

Next, we shall determine the number of mole of Br2 needed to produce 12 moles of AlBr3. This is illustrated below:

From the balanced equation above,

3 moles of Br2 reacted to produce 2 moles of AlBr3.

Therefore, Xmol of Br2 will produce 12 moles of AlBr3 i.e

Xmol of Br2 = (3 x 12)/2

Xmol of Br2 = 18 moles

Therefore, 18 moles of Br2 reacted to produce 12 moles of AlBr3.

Next, we shall convert 18 moles of Br2 to grams. This is illustrated below:

Number of mole Br2 = 18 moles

Molar mass of Br2 = 2 x 80 = 160g/mol

Mass of Br2 =.?

Mass = mole x molar mass

Mass of Br2 = 18 x 160 = 2880g

Next, we determine the volume of Br2 used in the reaction as follow:

Mass of Br2 = 2880g

Density of Br2 = 3.1g/mL

Volume of Br2 =..?

Density = Mass /volume

Volume = Mass /Density

Volume of Br2 = 2880/3.1

Volume of Br2 = 929mL

Finally, we shall convert 929mL to L.

1000mL = 1L

Therefore, 929mL = 929/1000 = 0.929L

Therefore, 0.929L of Br2 were used in the reaction.
