Answer/Explanation:

<u>Acids:</u>

Physical ⇒ Sour Taste, Increases the concentration of hydrogen ions when added to water

Chemical ⇒ Corrosive (Burns your skin and breaks down other materials), Forms hydrogen gas when it comes in contact with a metal, Forms salt and water when added to a base

Example: Tomatoes

<u>Bases:</u>

Physical ⇒ Bitter taste ( Never taste or smell a substance unless your parent/guardian tells you that it is okay), Slippery feeling(never touch a substance unless your parent/guardian tell you that is okay)

Chemical ⇒ Increases the concentration of hydroxide ions when added to water, Forms salt and water when added to an acid

Example: Soap, Clorox

Draw an alkyl bromide with proper stereochemistry that can be used to synthesize the given alkene as the exclusive product via a

enot [183]

Answer:

See explanation below

Explanation:

You forgot to put the picture to do so. In this case, I manage to find one, and I hope is the one you are looking for. If not, then post it again and I'll gladly help you out again.

According to the picture with the answer, we have a cyclohexane with 4 methyl groups there. Two of them are facing towards the molecule with a darker bond. This means that the alkyl bromide, should have a bromine in one of the bonds, and in order to produce an E2 reaction, this bromine should be facing in the opposite direction of the methyl groups which are facing towards. This is because an E2 reaction occurs with the less steric hindrance in the molecule. If the bromine is in the same direction as the methyl group, it will cause a lot more of work to do a reaction, and therefore, an E2 reaction. I will promote instead a E1 or a sustitution product.

Therefore the alkyl bromide should be like the one in the picture 2.

How many moles of nitrogen trifluoride (NF3) can be produced from 9.65 mole of Fluorine gas (F2)

user100 [1]

Answer:

6.43 moles of NF₃.

Explanation:

The balanced equation for the reaction is given below:

N₂ + 3F₂ —> 2NF₃

From the balanced equation above,

3 moles of F₂ reacted to produce 2 moles of NF₃.

Finally, we shall determine the number of mole of nitrogen trifluoride (NF₃) produced by the reaction of 9.65 moles of Fluorine gas (F₂). This can be obtained as follow:

From the balanced equation above,

3 moles of F₂ reacted to produce 2 moles of NF₃.

Therefore, 9.65 moles of F₂ will react to to produce = (9.65 × 2)/3 = 6.43 moles of NF₃.

Thus, 6.43 moles of NF₃ were obtained from the reaction.
