The answer is heterogeneous because if a salad is mixed by the following item it will not mix properly and we could easily separate them.

hope that helps you

have a great day!

Explanation:

A mixture in which solute particles are unevenly distributed into the solvent is known as a heterogeneous mixture.

For example, oil present in vinegar will unevenly mix together.

Whereas a mixture in which solute particles are evenly distributed into the solvent is known as a homogeneous mixture.

For example, salt dissolved in water is a homogeneous mixture.

Therefore, when a salad dressing is made by a chef by mixing oil, vinegar, and spices then it is a heterogenous mixture.

AlladinOne [14]

Answer:

The pure crystals were soluble in the wash solvent.

Explanation:

The pure crystals on the funnel dissolved because they were soluble in the solvent used for washing. They were carried into the filter flask by the solvent.

PLEASE HELP!! What is the concentration [H3O+] of a solution with a pH of 13.2? Is the solution acidic, basic, or neutral?

Ilya [14]

The concentration of [H3O+] will be 6.3 x $10^{-14}$ M

Mathematically, pH = -log [H+] or -log [H3O+]

With a pH of 13.2:

-log [H3O+] = 13.2

log [H3O+] = -13.2

[H3O+] = 6.3 x $10^{-14}$ M

Iron fluoride (FeF2) dissociates according to the following equation:

melomori [17]

Answer:

S = 0.788 g/L

Explanation:

The solubility product (Kps) is an equilibrium solubization constant, which can be calculated by the equation:

$Kps = \frac{[product]^x}{[reagent]^y}$

Where x and y are the stoichiometric coefficients of the product and the reagent, respectively. Because of the aggregation form, the concentration of solids is always equal to 1 for use in this equation.

Analyzing the equation, we see that for 1 mol of $Fe^{+2}$ is necessary 2 mols of $F^-$ , so if we call "x" the molar concentration of $Fe^2$ , for $F^-$ we will have 2x, so:

$Kps = [Fe^{+2}].[F^-]^2\\\\2.36x10^{-6} = x(2x)^2\\\\2.36x10^{-6} = 4x^3\\\\x^3 = 5.9x10^{-7}\\\\x = \sqrt[3]{5.9x10^{-7}} \\\\x = 8.4x10^{-3} mol/L$

So, to calculate the solubility (S) of FeF2, which is in g/L, we multiply this concentration by the molar mass of FeF2, which is:

Fe = 55.8 g/mol

F = 19 g/mol

FeF2 = Fe + 2xF = 55.8 + 2x19 = 93.8 g/mol

So,

[tex]S = 8.4x10^{-3}x93.8

S = 0.788 g/L
