Nezavi [6.7K]3 years ago

Answer:

The first thing you will need to do is find some information about your element. Go to the Periodic Table of Elements and click on your element. If it makes things easier, you can select your element from an alphabetical listing.

Number of Protons = Atomic Number

Number of Electrons = Number of Protons = Atomic Number

Number of Neutrons = Mass Number - Atomic Number

For krypton:

Number of Protons = Atomic Number = 36

Number of Electrons = Number of Protons = Atomic Number = 36

Number of Neutrons = Mass Number - Atomic Number = 84 - 36 = 48

hope this helps, have a good day :-)

Question 1<br><br> Of the following which displays a positive energetic process?
TiliK225 [7]

We can describe a positive energetic process as any process which increases the internal energy of the system.

A positive energetic reaction or process is often referred to as being Endothermic. This means that the system which is performing the process absorbs energy. Some examples include:

  • Boiling an Egg
  • Roasting food over a fire (the food is the reference system)

etc

Therefore, we can confirm that a positive energetic process is one in which the system in question absorbs energy, thus increasing its internal energy.

<em>Since I could not locate the options online, I have provided a general explanation of the concept coupled with a few examples.</em>

A gravel can be broken down into different kinds of substances by physical processes. No chemical reactions are needed to separa
Vlada [557]

Answer:

MIXTURE

Explanation:

A mixture is a substance composed of a combination of other different substances. These component(s) of a mixture are physically combined, meaning that there is no chemical linkage between the individual components/constituents of a mixture.

This is the case of the gravel described in this question. The components of gravel can be separated using physical means because they are not chemically bonded to one another, hence, no chemical reactions are needed to separate different parts of gravel into pure substances. This makes gravel a MIXTURE.
