Ivanshal [37]

Answer:

-3.06 is the overall voltage produced

Explanation:

Potassium and Tin are connected in an electrochemical series.

In a series circuit, the resultant voltage is equal to the sum of voltage drops at all points in the circuit.

Here,

The voltage drop at potassium = -2.92

The voltage drop at Tin = -0.14

The net voltage

= -2.92 -0.14 \\= -3.06

To separate liquids in a mixture of different liquids, each having different boiling points, one would use the separation techni
sleet_krkn [62]

Answer;

-Distillation

Explanation;

Distillation is a  technique that can be used to physically separate most homogeneous mixtures based on the difference in the boiling points of the substances involved.

A good example;  A flask hold liquids A, B, and C in a homogeneous mixture. The boiling points of A, B, and C are 130 C, 65 C, and 71 C, respectively. The flask is heated to 65C until all of liquid B is filtered out. The remaining mixture is heated to 71C until all of liquid C is filtered out, and only liquid A is left in the flask.

In terms of acids and bases, what does neutralization mean?.
egoroff_w [7]

Answer:

Neutralization is when the pH (power of hydrogen ions) of a solution is at 7 (considered neutral in the pH scale). This means it's neither acidic nor basic and is neutral. In order to neutralize an acidic solution, you pour in the same amount of a strong base. And in order to neutralize a basic solution, you pour in the same amount of a strong base.

A neutralization reaction will give you salt and water. A common neutralization reaction could be:

HCl (strong acid) + NaOH (strong base) ----> NaCl (Salt) + H2O (water)
