An organism is said to have a prokaryotic cell if its cell is a very simple one that does not contain any true nucleus and which do not have membrane bound organelles. Prokaryotes are usually unicellular organisms, examples are bacteria. One key feature of prokaryotic cell is a piece of circular, double stranded DNA which is usually found in the cell.

An atom of oxygen (atomic number 8) has a mass number of 17. How many neutrons are<br> in that atom?
ludmilkaskok [199]
<h2>Answer:  # of neutrons = 9</h2>

<h3>Explanation:</h3>

# of neutrons = mass number - atomic number

                      = 17 - 8

                      = 9

<h3>∴ number of neutrons in an atom of oxygen of mass number 17, is 9.</h3>

In a two-step synthesis, C6H11Br is converted into C6H12O. From the structure of the product, molecular formula of the starting
tamaranim1 [39]

Answer:

See explanation below

Explanation:

The question is incomplete. However in picture 1, you have the starting materials and the structure of the product, which you miss in this part.

Now, in picture 2, you have the starting reactant and the product, and the mechanism that is taking place here.

First, all what we have here is an acid  base reaction. In the first step, we are using the acid medium to convert the reactant into an alcohol. The bromine there, is not leaving the molecule yet, because it's neccesary for the next step. The starting reactant is an alkene, in that way, we can convert the reactant in the first step into a secondary alcohol. In other words, the first reaction is a alkene hydration.

In the second step, we use a strong base. You may say this is a strong nucleophile and will do a Sn2 reaction to form another alcohol there, but it's not the case, because, before any kind of reaction happens, the priority here is always the acid base, so the base will react with the acidic hydrogen. In this case, it will substract an hydrogen from the OH. When this happens, the lone pair will do an auto condensation here, and attacks the bromine in the molecule. In this way, the molecule will become a cyclomolecule, and that way it form the final product.

See picture 2, for mechanism
