Questions and Answers
- 1.
An ion with a positive electrical charge
- A.
Anion
- B.
Proton
- C.
Atom
- D.
Cation
Correct Answer
D. CationExplanation
A cation is an ion with a positive electrical charge. An ion is an atom or molecule that has gained or lost one or more electrons, resulting in a net positive or negative charge. In the case of a cation, it has lost one or more electrons, leaving it with more protons than electrons and therefore a positive charge. Therefore, a cation is the correct answer in this case.Rate this question:

Positive electrode.
- A.
Cathode
- B.
Anode
- C.
Amp
- D.
Cation
Correct Answer
B. AnodeExplanation
The correct answer is anode. In an electrochemical cell, the anode is the electrode where oxidation occurs, meaning it loses electrons. It is positively charged and attracts negatively charged ions or anions. The cathode, on the other hand, is the electrode where reduction occurs, meaning it gains electrons. Therefore, the anode is the appropriate term to describe the positive electrode in this context.Rate this question:

Chemical reactions that produce heat.
- A.
Endothermic
- B.
Ionization
- C.
Exothermic
- D.
Chemical change
Correct Answer
C. ExothermicExplanation
Exothermic refers to chemical reactions that release heat energy. This means that during the reaction, energy is being released into the surroundings in the form of heat. In contrast, endothermic reactions absorb heat energy from the surroundings. Ionization refers to the process of forming ions, and chemical change is a broad term that encompasses any transformation of one substance into another. Therefore, the correct answer is exothermic because it specifically describes chemical reactions that produce heat.Rate this question:

- A.
Alternating current
- B.
Direct current
- C.
Tesla high-frequency current
- D.

Combinations of two or more atoms of different elements chemically joined together.
- A.
Molecules
- B.
Emulsions
- C.
Solutions
- D.
Compounds
Correct Answer
D. CompoundsExplanation
Compounds are formed when two or more atoms of different elements are chemically bonded together. This chemical bonding creates a new substance with different properties than the individual elements. Compounds have a fixed ratio of atoms and can only be separated through chemical reactions. Molecules, emulsions, and solutions can also consist of two or more atoms or elements, but they do not necessarily involve a chemical bond between the atoms. Therefore, compounds are the correct answer in this context.Rate this question:

C. CataphoresisExplanation
Cataphoresis is the process of forcing acidic substances into deeper tissues using galvanic current from the positive toward the negative pole. This process is commonly used in various medical and cosmetic treatments. It is achieved by applying a positive electrode with the acidic substance to the desired area, and the galvanic current helps to push the substance deeper into the tissues. Cataphoresis is effective in delivering medications or treatments to specific areas, providing targeted and localized benefits.Rate this question:

A molecule is a chemical combination of two or more atoms. It is formed when atoms bond together through chemical reactions. Molecules can be made up of atoms of the same element or different elements. They are the smallest units of a compound that retain the chemical properties of that compound. Molecules can exist as individual units or as part of a larger structure. In this context, the term "molecule" is the correct answer as it best describes the chemical combination of atoms.Rate this question:

The simplest form of matter; it cannot be broken down into a simpler substance without a loss of identity
- A.
Atom
- B.
Molecule
- C.
Element
- D.
Ion
Correct Answer
C. ElementExplanation
An element is the simplest form of matter that cannot be broken down into a simpler substance without losing its identity. Each element is made up of only one type of atom, which is the basic building block of matter. Elements are represented by unique symbols on the periodic table, such as H for hydrogen or O for oxygen. Unlike molecules, which are made up of multiple atoms bonded together, elements exist independently and retain their distinct properties. Similarly, ions are atoms or molecules that have gained or lost electrons, but they are not the simplest form of matter.Rate this question:

Rapid and interrupted current, flowing first in one direction and then in the opposite direction
- A.
Direct current (DC)
- B.
Alternating current (AC)
- C.
Galvanic current
- D.
Watt
Correct Answer
B. Alternating current (AC)Explanation
The given description of "Rapid and interrupted current, flowing first in one direction and then in the opposite direction" matches the characteristics of alternating current (AC). In AC, the flow of electric charge periodically changes direction, typically at a frequency of 50 or 60 cycles per second. This is in contrast to direct current (DC), where the flow of electric charge is constant in one direction. Galvanic current refers to a direct current produced by a galvanic cell, and a watt is a unit of power.Rate this question:

- A.
Alternating current (AC)
- B.
Direct current (DC)
- C.
Galvanic current
- D.
Electric current
Correct Answer
C. Galvanic currentExplanation
The correct answer is galvanic current. Galvanic current is a type of direct current that has a positive and negative pole and produces chemical changes when it passes through the tissues and fluids of the body. It is commonly used in electrotherapy and can be used for various purposes such as muscle stimulation, pain relief, and skin rejuvenation. Alternating current (AC) refers to the flow of electric charge that periodically reverses direction, while direct current (DC) refers to the flow of electric charge in one direction only. Electric current is a general term that encompasses both AC and DC.Rate this question:

- B.
Anion
- C.
Element
- D.
Atom
Correct Answer
B. AnionExplanation
An anion is an ion with a negative electrical charge. It is formed when an atom gains one or more electrons. The negative charge is due to the excess of electrons compared to the number of protons in the atom. Anions are attracted to the positive terminal of a battery or an electric field. In contrast, a cation is an ion with a positive charge, formed when an atom loses one or more electrons.Rate this question:
