Most lakes have rivers flowing out of them, carrying water to the ocean. However, some lakes, including Great Salt Lake and the
Kaylis [27]

Since the only way of water flow to these lakes or bodies of water is through evaporation, I would expect an increase in unknown substances in the composition of the lakes due to the amount of contamination that globalization produces and affects terribly the surroundings when these unknown substances travel through evaporation as the outlet of these bodies of water. Therefore I think continuous contamination is what to expect after many more years of inflow and evaporation.

What does the number of valence electrons determine?
N76 [4]

Valence electrons are the electrons in the outermost shell of an element on the periodic table. Atoms want to be able to have a full outer shell and they can share or trade electrons in order to achieve this. Valence electrons are also super super important in chemical reactions. The number of valence electrons determines what group that specific atom or element is in on the periodic table. This affects the reactivity of the element.

The volume of a sphere is given by V-(4/3)r where r is the radius. The density of magnesium is 1.74 g/cm What is the mass of a m
kicyunya [14]

Answer:

The answer to your question is:

mass = 3.74 g

Explanation:

Data

V = (4/3) πr³

density = 1.74 g/cm³

radius = r = 0.80 cm

Process

V = (4/3) π(0.8)³             Substitution

V = 2.1446 cm³

mass = density x volume

mass = 1.74 x 2.1446      Substitution

mass = 3.74 g

I don't understand if the second section is also a question.
