Answer: Option (c) is the correct answer.

Explanation:

An ionic bond is defined as the bond which occurs when there will be transfer of electrons between the combining atoms.

For example, potassium donating an electrons to chlorine atom will result in the formation of an ionic bond.

So, the analogy presented by student C, shows that greedy dog stole away the bone from a smaller dog. This is similar to an atom whose one valence electron is readily taken away by an electron deficient atom.

Thus, we can conclude that out of the given options, student C: A big, greedy dog stealing away a bone from a smaller dog, presented a correct analogy.

The direction of electrical force is based on the fact that like charges will___each other.

NeTakaya

Answer:

repel

Explanation:

When it comes to electrical forces, "opposites charges attract" while "like charges repel."

There are primarily two types of charges: positive charge and negative charge. The forces they exert upon each other will depend on their charges. The positive charge has an attractive force to a negative charge. On the contrary, it has a repulsive force to the same positive charge. Thus, it will repel each other.

So this means that opposite charges will draw closer together while like charges will move apart from each other.

In an electrolytic cell, the electrode that acts as a source of electrons to the solution is called the __________; the chemical

Romashka [77]

In an electrolytic cell, the electrode that acts as a source of electrons to the solution is called the cathode; the chemical change that occurs at this electrode is called reduction.

<h3>Define Electrolyte:-</h3>

An electrolyte is a material that separates into charged ions when it is in contact with water. Cations are positively charged ions. Anions are ions that are negatively charged. A substance that may conduct an electric current when melted or dissolved in water is known as an electrolyte.

<h3>Electrochemical cell </h3>

There are three main categories of electrochemical cells. the galvanic cell, the concentration cell, and the electrolytic cell. These cells all share the same four fundamental components. These are the elements

The electrolyte serves as the conduit for current flow between the anode and the cathode. In an aqueous solution, it normally is homogeneous, but in moist soil, the concentration or kind of dissolved compounds may vary locally.
The anode, which can conduct electricity and is in contact with the electrolyte, corrodes when it combines with the chemicals in the electrolyte.
A metal also contacts the electrolyte at the cathode. It is protected from corrosion rather than corroded.
Anode and cathode are connected by the conductor, which also completes the circuit.

You find a mysterious bottle in the laboratory labeled 0.01 M Sodium Hydroxide. What is the pH of the solution?

andrey2020 [161]

Answer: pH of the solution is 12

Explanation:

NaOH —> Na+ + OH-

NaOH = 0.01M

Na+ = 0.01M

OH- = 0.01M

pOH = —log [OH-] = —log [0.01]

pOH = 2

pH + pOH = 14

pH = 14 — pOH = 14 — 2 = 12

pH = 12
