Answer:

2. It is the simplest ratio of atoms in a formula unit.

Explanation:

The empirical formula refers to how to provide the minimum proportion in which chemical elements combine into one substance. Sometimes it may happen that the minimum formula is equal to the molecular formula of the compound; However, this is not always true.  In short, the empirical formula refers to the simplest ratio of atoms in a unit of formula.

For example, the empirical or minimal formula of water is H2O, indicating that there is a 2: 1 ratio between the elements that make up water molecules. And, coincidentally, this is also the molecular formula of water.

How is atomic number different from mass number?
Nimfa-mama [501]
Hello Gary My Man!

Well, as you can clearly see 

<span>The atomic number of an element is basically the number of protons it has. So yes, for every element this is different. Now, the mass number of an element as known, is the number of protons+the number of neutrons.  So theoretically as we can see, this number should be a whole number, but since there are different isotopes (atoms of the same element with different numbers of neutrons) of each element, most periodic tables take account of that, so they often include decimals as seen. 

So in Short, ALL</span> the atoms of a particular element have the SAME EXACT atomic number<span> (</span>number<span> of protons of course). The </span>atoms of different elements have very different numbers of protons. And of course, the MASS number of an atom is the TOTAL number as known, of protons and of course, the neutrons it contains in it.

I Hope my answer has come to your Help. Thank you for posting your question here in Brainly. We hope to answer more of your questions and inquiries soon. Have a nice day ahead! :)

Tpy6a [65]

Answer:

Rain shadow

Explanation:

Climate is the average weather condition of a place over a long period of time.

The image shows a rain shadow effect around a mountainous region. The type of rainfall controlled this way is known as an orographic rainfall.

  • On the leeward side which is the opposite side of where the rain cloud forms, there is dryness and lack of rainfall.
  • As moist air rises along the edge of the windward side, cloud forms.
  • This windward side receives a significant amount of rainfall
  • The windward side is hit with cold and dry wind and it is barren.

In chemistry, solvent extraction is accomplished by adding a sample containing the substance to be separated into a system of two solvents, an aqueous layer and an organic layer.

It is important to note that all the layers should be kept until the experiment is complete. No layer ought to be discarded before the work is completed.
