Mixtures are of 2 types.
1) Homogeneous mixture : In this type of mixture, the components of the mixture are present in the same phase. For example, Air. Air is a mixture of different gases which cannot be distinguished from each other.
2) Heterogeneous mixture : In this type pf mixture, 2 or more phases can be seen. The composition of the different components is not the same throughout the mixture.
Ex. mixture of oil and water. Here we can see 2 different phases one consisting of oil layer and the other made of water layer.
Salt water is a mixture of salt and water. Since salt is completely soluble in water, it creates a homogeneous mixture when mixed with water. We cannot distinguish salt and water once they are mixed.
To get fresh water from the salt water in the ocean, we can set up a simple distillation unit . In this, the salt water is heated to its boiling point and the vapors thus formed are allowed to cool which condense and create liquid water. This can be used as fresh water.

they would be HUGE....and i don't want that
Explanation:
<span>Why are valence electrons important?
Valence electrons are the electrons present farthest from nucleus. These valence electrons are either transferred or shared during a reaction. Some elements like metals donate valence electrons in ionic compound formation, while some like Carbon mutually share thier valence electrons to make a covalent bond. Hence, it is the valence electrons that make any element reactive or unreactive.
</span><span>Why do elements bond?
Elements react in order to gain stability. This stability is gained in the form of attaining noble gas configuration either by donating, gaining or mutually sharing their valence electrons.
</span><span>What are two ways elements complete their valence?
The two ways are transfer of electrons and mutual sharing of electrons.
Example:
Sodium looses one valence electron to obtain Noble gas configuration of Neon which is more stable configuration.
Chlorine gains one electrons to obtain Noble Gas configuration of Argon which is more stable configuration.
Carbon mutually shares its four valence electrons with four atoms of Hydrogen having one electron per atom to complete its octet.</span>
Answer:
<h2>Density = 5.24 g/cm³</h2>
Explanation:
The density of a substance can be found by using the formula
<h3>
</h3>
From the question
mass = 52.4 g
volume = 10 cm³
Substitute the values into the above formula and solve for the density
That's
<h3>
</h3>
We have the final answer as
<h3>Density = 5.24 g/cm³</h3>
Hope this helps you
