Water and a nonpolar substance will need to be forcibly mixed. this best describes a(n):__________

emulsion

What is emulsion?

a colloid system in which both the dispersed phase and the dispersion medium are liquids; a mixture of two immiscible liquids, one of which is scattered throughout the other in tiny droplets.

Emulsions include margarine, cold cream, and numerous medicinal ointments. Every time an emulsion is used, the container must be shaken since some emulsions have a tendency for the suspended particles to stick together and settle out.

Applied to a suitable foundation, a dehydrated gel emulsion of light- or radiation-sensitive silver halide is known as a film emulsion.

If 5.12 liters of a 2.75 M phosphoric acid is neutralized by magnesium hydroxide solution of 4.00 M.

Tresset [83]

Answer:

5.28 L

Explanation:

Step 1:

Data obtained from the question.

Volume of acid (Va) = 5.12L

Molarity of acid (Ma) = 2.75M

Molarity of base (Mb) = 4M

Volume of base (Vb) =.?

Step 2:

The balanced equation for the reaction

2H3PO4 + 3Mg(OH)2 → Mg3(PO4)2 + 6H2O

From the balanced equation above,

Mole ratio of the acid (nA) = 2

Mole ratio of the base (nB) = 3

Step 3:

Determination of the volume of the base.

This is illustrated below:

MaVa/MbVb = nA/nB

2.75 x 5.12 / 4 x Vb = 2/3

Cross multiply

4 x 2 x Vb = 2.75 x 5.12 x 3

Divide both side by 4 x 2

Vb = (2.75 x 5.12 x 3)/(4 x 2)

Vb = 5.28 L

Therefore, the volume of the base is 5.28 L

A compound accepts electrons from another substance to form a covalent bond. Which term best describes this compound’s behavior?

Cloud [144]

A compound accepts electrons from another substance to form a covalent bond. The compound acts as a Lewis base.

<h3>What are the most common acid-base theories?</h3>

Arrhenius: acids release H⁺ and bases release OH⁻.
Bronsted-Lowry: acids donate H⁺ and bases accept H⁺.
Lewis: acids accept electrons and bases donate electrons.

A compound accepts electrons from another substance to form a covalent bond. Which term best describes this compound’s behavior?

Lewis acid. YES.
Arrhenius base. NO, because OH⁻ is not involved.
Bronsted-Lowry acid. NO, because H⁺ is not involved.
Bronsted-Lowry base. NO, because H⁺ is not involved.

ahrayia [7]

Answer:

Ionic bond

Explanation:

When Na loses an electron, it becomes positive ion.

When Cl gains an electron, it becomes negative ion.

The electrostatic attraction between these ions is an ionic bond.
