You have 34.1 x 1023 molecules of O2. How many moles of O2 do you have? Fill in the grid. Then, solve the problem and answer the
denis-greek [22]

Number of moles = 5.7 moles of oxygen.

<u>Explanation:</u>

We have to convert number of molecules into number of moles by dividing the number of molecules by Avogadro's number.

Here number of molecules of oxygen given is 34.1 × 10²³ molecules.

Now we have to divide the number of molecules by Avogadro's number as,

Number of moles = $\frac{number of molecules}{Avogadro's number}

                            = $\frac{34.1}{6.022} \times \frac{10^{23} }{10^{23} }

                          = 5.7 moles

So here molecules is converted into moles.

mojhsa [17]

Answer:

The change in color.

Explanation:

The apple turn brown in color because of the oxidation process. When the oxygen and water molecules in air react with it, oxidation take place. The oxidation process is very efficient in ambient temperature.

For example, if the peal off apple is placed into the refrigerator it take a time to got oxidize and turn brown, but if it is placed in room temperature it quickly turn brown.

when oxygen is react with peel off apple , it trigger the polyphenol oxidase enzyme to oxidize the phenolic compound and quinones are formed which then react with amino acids and produced brown color.
