Compare the following sodium atoms in terms of their neutrons and mass numbers 24Na, 23Na​
olga_2 [115]

Na-24 and Na-23 have the same number of atoms=11, different neutrons(13 and 12),different mass number(24 and 23)

<h3>Further explanation </h3>

The elements in nature have several types of isotopes

Isotopes have the same number of protons and having a different number of neutrons.

So Isotopes are elements that have the same Atomic Number (Proton)

  • ₁₁²³Na

number of atoms = 11

mass number = 23

number of neutrons=23-11=12

  • ₁₁²⁴Na

number of atoms = 11

mass number = 24

number of neutrons=24-11=13

sound travels at 331m/s. How long would it take for sound to travel across lake tahoe, which is 21.6 miles long
vesna_86 [32]

Answer:

It would take sound <em><u>104.998 seconds</u></em> to travel across lake tahoe.

Explanation:

First let's convert the miles to meters, so, 21.6 miles = 34754.4 meters

Now, we will divide this number in meters by 331. So, 34754.4 / 331 = 104.998

And what will the unit be? Seconds will be the unit for time here so 104.998 seconds.

While hiking in the woods, you see a brown, rotting apple lying on the ground. What changes is the physical properties of the ap
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.
