Provide the missing arrows in the boxes to show how br2 is produced from nbs

Illusion [34]

Answer: -

The mechanism for Br production from NBS is shown in the attached file.

N-bromo succinimide is a reagent used to brominate. It is most commonly used in allylic bromination, where a hydrogen on a carbon adjacent to a double bond is replaced.

It is selective in nature, unaffecting the normal double bond as compared to only bromine.

It also has a low concentration of bromine as an added advantage.

In a 45 minute road trip a vehicle emitted 16. 7 g of nitrogen dioxide (NO2) from its exhaust. What is the mass of nitrogen atom

shepuryov [24]

When a 45-minute road trip a vehicle emitted 16.7 g of nitrogen dioxide (NO₂) from its exhaust then the mass of nitrogen atoms in this amount of NO₂ would be 5.082 grams.

<h3>What is a Chemical compound?</h3>

The chemical compound is a combination of two or more either similar or dissimilar chemical elements.

for example, H₂O is a chemical compound made up of two oxygen atoms and a single hydrogen atom

The molecular mass of any compound is calculated by the sum of the mass of the individual atom

As given in the problem In a 45-minute road trip a vehicle emitted 16.7 g of nitrogen dioxide (NO₂) from its exhaust

The molecular mass of the NO₂ is the sum of the mass of the nitrogen atom and the oxygen atom.

The mass of the single nitrogen atom is 14, while the mass of the single oxygen atom is 16

the molecular mass of NO₂= mass of the N atom+2×(mass of O atom)

= 14 + 2×16

=46

As 46 grams of NO₂ contain 14 grams of Nitrogen

then 1 gram of NO₂ would contain 14/46 grams of Nitrogen

then 16.7 grams of NO₂ would contain (14/46×16.7) grams of Nitrogen

The mass of a nitrogen atom in 16.7 grams of NO₂ would be 5.082 grams

Determine the specific heat of a 70 g sample of material that absorbed 96 J as it was heated from 293 K to 313 K

Damm [24]

This problem is providing us with the mass (70 g), absorbed heat (96 J) and initial and final temperatures (293 K and 313 K, respectively) so the specific heat of the material is required and found to be 0.0686 J/(g*K) as shown below:

<h3>Calorimetry:</h3>

In chemistry, we can go over calorimetry by writing the following relationship among heat, mass, specific heat and temperature change:

$Q=mC(T_f-T_i)$

Thus, one can get the specific heat by solving for C in the previous equation:

$C=\frac{Q}{m(T_f-T_i)}$

Hence, we can plug in the given data to obtain:

$C=\frac{96J}{70g(313K-293K)}\\ \\C=0.0686\frac{J}{g*K}$
