I never understand these questions so let’s just look at them logically

Leaving the room: Makes enough sense, in the event that the “accident” is lethal, you don’t really want to be there.

Calling the paramedics: I feel like this is an overreaction, the “accident” might not even be serious

Locate the first aid kit: Also in the same vein as paramedics, what are the chances that the accident causes harm

Call a teacher: They should know what to do, or at least, they’re the “adults”, so that’s probably your best bet

Answer:

Tell your teacher or learning coach.

Explanation:

It is always best to let an experienced teacher or coach know what has happened, so they may address it carefully and correctly.

Hope this helps : )

Refer to the balanced equation. (PLEASE HELP QUICK)

Answer: C) $5.12\times 10^1$ L $Cl_2$

Explanation: $8H_2S+8Cl_2\rightarrow S_8+16HCl$

According to Avogadro's law, 1 mole of every gas occupies 22.4 Liters at STP.

Thus from the balanced chemical equation, 8 moles of hydrogen sulfide reacts with 8 moles of chlorine gas.

i.e 8 moles of hydrogen sulfide reacts with $=8\times 22.4L=179.2L$ of chlorine gas.

2.28 moles of hydrogen sulfide reacts with $=\frac{179.2}{8}\times 2.28=51.2L=5.12\times 10^1L$ of chlorine gas.

1. Show the mechanism for the main product for the monochlorination of 2-methylbutane. List all other products.

Bad White [126]

Answer:

See explanation below

Explanation:

First, we need to understand that the monochlorination of an alkane like this one, involves substitution of one of the atoms of hydrogen of the molecule for an atom of chlorine.

This reaction takes place when the alkane reacts with Cl₂ in presence of light or heat.

When this happens, the first step involves the breaking of the double bond of the chlorine to form the ion Cl⁻.

The next step involves the substraction of the hydrogen of the molecule by the Chlorine. This will leave the alkane with a lone pair available for reaction.

The third step, the alkane with the lone pair of electron substract a chlorine for the beggining and form the mono chlorinated product.

The final step involves forming the remaining products with the remaining reagents there.

In the picture attached you have the mechanism and product for this reaction:

After adding 20.0 mL of 5% NaOH solution into the remaining organic layer, followed by mixing and venting, the solution separate

Arisa [49]

Answer:

Explanation:

The objective of this experiment is to match the expected result with each of the propositions given after the experiment had been carried out.

1. The top layer was the organic  layer. This is because all the organic compounds have lesser density than water except chloroform that will be formed when NaOH is added.

2. 9-fluorenone was most soluble in the organic layer. This is so as a result of its non-polar carbon structure.

3. Deprotonated chloroanilic acid was most soluble in the aqueous layer as a result of the formation of an electrovalent bond with water.

4. The bottom layer was the aqueous layer as a result of the huge amount of water density.

5. The organic layer was a yellow colored solution.

6. The aqueous layer turned into a pink colored solution.
