Can the filtration process be used to separate salt water? Why?

Chemistry

Not by filtration as liquid passes through the filter but not a solid. however, by using the process of distillation, you can heat the water to boiling point to cause evaporation. when the water evaporates only the solid salt will be left and separated.

How are skepticism and open-mindedness different? How are they alike?
Sphinxa [80]
Skepticism is saying that something doesn't feel right or you think that something isn't real, Open-mindedness is when you will take any idea or will be free to suggestions. Just my lucky guess.

What type of bonds exist in each of these compounds?
kodGreya [7K]

Answer:

a) ionic     b) polar covalent    c) nonpolar covalent

Explanation:

To determine if a bond is covalent or ionic without knowing the electronegativities is to see if it is a metal-nonmetal bond or a nonmetal-nonmetal bond.  Metal-nonmetal bonds are ALWAYS ionic, and nonmetal-nonmetal bonds are ALWAYS covalent.  A is the metal-nonmetal bond and thus ionic.  B & C are both nonmetal-nonmetal bonds and thus covalent.

Polarity:

To determine if a covalent bond is polar or not, we need to see how far apart the elements are away from one another.  The further away the elements are from one another the more polar the bond.  Nonmetal elements bonded to themselves are ALWAYS nonpolar see compound C.  For B, the elements are far apart and are still covalent, so these bonds are polar.

If oxygen with an electronegativity of 3.5 were to make a chemical bond with lithium, electronegativity of 1.0, what kind of bon
sergejj [24]

Answer:

Ionic.

Explanation:

Elements with higher electronegativity values are better at attracting electrons in a chemical bond.  

  • A chemical bond is considered "ionic" if the electronegativity difference between the two bonding atoms is greater than 1.8.
  • Otherwise, this chemical bond is considered "covalent".

In this example, the difference between the electronegativity of oxygen and lithium is 3.5 - 1.0 = 2.5. Since 2.5 > 1.8, the bond between the two elements would likely be ionic.

It is possible to reach the same conclusion based on the fact that lithium is a metal while oxygen is a nonmetal. When metal elements react with non-metal elements, the product is typically an ionic compound- with ionic bonds between the atoms.
