Write differences between homogeneous mixture and heterogeneous mixture​

Chemistry

Pie2 years ago

Answer:

Homo means same

Hetero means different.

Homogeneous mixtures have one phase, it all looks the same, Fruit juice is homogeneous, solutions are homogeneous.

Heterogeneous mixtures have different phases, you can see the different parts, pepper is an example of a heterogeneous mixture.

  • A homogeneous mixture - Think Kool Aid (Completely Dissolved)
  • A heterogeneous mixture - Like pepper poured into a glass of milk.

In a homogeneous mixture the constituents are able to dissolve in each other due to their similar intermolecular forces, whereas in a heterogeneous mixture the constituents are not miscible- meaning they can't dissolve in each other.

To clarify: intermolecular forces describe the way that types of molecules will interact with each other. For instance, water (a polar molecule) and naphthalene (a non-polar molecule) are said to be "immiscible" because their intermolecular forces do not match. The saying goes: "like dissolves like". Meaning that molecules that have similar IFs will be mutually soluble (miscible, in other words).

  • Homogenous means the same all over...every cubic millimeter is about the same as every other one. Like water or soda.
  • Heterogenous means difference in places, like salsa, with slightly different chunks of stuff depending on where you dipped your chip.

  • Avogadro's Number - 6.022 × 10²³ atoms, molecules, formula units, etc.
<h3>Explanation:</h3>

<u>Step 1: Define</u>

50.3 mol KCl (Potassium chloride)

<u>Step 2: Identify Conversions</u>

Avogadro's Number

<u>Step 3: Convert</u>

<u />\displaystyle 50.3 \ mol \ KCl(\frac{6.022 \cdot 10^{23} \ formula \ units \ KCl}{1 \ mol \ KCl} ) = 3.02907 × 10²⁵ formula units KCl

<u>Step 4: Check</u>

<em>We are given 3 sig figs. Follow sig fig rules and round.</em>

3.02907 × 10²⁵ formula units KCl ≈ 3.03 × 10²⁵ formula units KCl
