Extraction Of Iron And Basic Electrolysis Quiz
In this quiz we’ll be taking a look at two subjects regarding the scientific study of chemistry: iron extraction and the process of electrolysis, which is a technique that involves using a direct electric current to drive an otherwise non-spontaneous chemical reaction. What do you know about them?
- 1.
What is the main components of iron ore?
- A.
Iron Oxide and Silica
- B.
Silica and Oxide
- C.
Iron and Silicone
- D.
Iron Oxide and Silico
- E.
Iron Oxide and Silicone
Correct Answer
A. Iron Oxide and SilicaExplanation
The main components of iron ore are iron oxide and silica. Iron oxide is the primary component of iron ore, while silica is a common impurity found in iron ore. Iron oxide gives iron ore its characteristic red color and is the main source of iron in the ore. Silica, on the other hand, is a compound that is often found in rocks and minerals, including iron ore. It is a common impurity in iron ore and needs to be removed during the processing of iron ore to obtain pure iron.Rate this question:

Choose the correct definition of oxidation
- A.
The addition of oxygen to a molecule with too many protons
- B.
The subtraction of oxygen to a compound with a loss of electrons
- C.
The addition of oxygen to a compound with a loss of protons
- D.
The subtraction of oxygen to a compound with too many protons
- E.
The addition of oxygen to a compound with a loss of electrons
Correct Answer
E. The addition of oxygen to a compound with a loss of electronsExplanation
Oxidation is a chemical process in which a substance loses electrons. In this process, oxygen is added to a compound, resulting in the loss of electrons from that compound. This definition aligns with the given correct answer, which states that oxidation is the addition of oxygen to a compound with a loss of electrons.Rate this question:

An electrode is a part of a circuit that _____ ________.
Correct Answer
conduct electricity
conducts electricityExplanation
An electrode is a part of a circuit that conducts electricity.Rate this question:
- 4.
Choose the correct definition of Anion
- A.
Anion is an ion that is negatively charged.
- B.
Anion is an ion that is positively charged.
- C.
Anion is an ion that has neither negative or a positive charge.
Correct Answer
A. Anion is an ion that is negatively charged.Explanation
Anion is defined as an ion that carries a negative charge. This means that it has gained one or more electrons, resulting in an excess of negative charge. Anions are attracted to the positive electrode (anode) in an electrolytic cell and are involved in various chemical reactions.Rate this question:

Electrolysis _____ compounds using an ______ current.-----------SEPARATE ANSWERS WITH A COMMA.e.g.Scruffy is a dog. A dog is an ____. The scientific name for dog is ____.animal, canine---------------
Correct Answer
separate, electric
separates, electrical
electrical, separate
electric, separatesExplanation
Electrolysis is a process that separates compounds using an electric current.Rate this question:
- 6.
An anode is a __________
Correct Answer
positively charged electrode
Positively Charged Electrode
Positively charged Electrode
Positively charged electrode
An electrode that is positively chargedExplanation
An anode is a positively charged electrode. This means that it carries a positive charge and attracts negatively charged particles. In an electrochemical cell, the anode is where oxidation occurs, releasing electrons and allowing the flow of current. The other options are simply variations of the correct answer, emphasizing that the anode is positively charged and plays a crucial role in electrical processes.Rate this question:
- 7.
A Cathode is the _______ of Anode; it is a _______ charged electrode.----------- SEPARATE ANSWERS WITH A COMMA. e.g. Scruffy is a dog. A dog is an ____. The scientific name for dog is ____. animal, canine ---------------
Correct Answer
Opposite, Negatively
opposite, negatively
opposite, negative
Opposite, NegativeExplanation
A Cathode is the opposite of Anode; it is a negatively charged electrode.Rate this question:
- 8.
Electrolysis only happens with _______ compounds.
Correct Answer
Ionic
ionicExplanation
Electrolysis is a process that involves the decomposition of an electrolyte through the passage of an electric current. An electrolyte is a substance that conducts electricity when dissolved in water or melted. Ionic compounds are formed by the combination of positively and negatively charged ions, and they readily dissociate into ions in a solution or when melted. Therefore, only ionic compounds can undergo electrolysis, as they provide the necessary ions for the conduction of electricity.Rate this question:
- 9.
Ionic compounds contain ______. They are not ______ or ______ charged. ----------- SEPARATE ANSWERS WITH A COMMA. e.g. Scruffy is a dog. A dog is an ____. The scientific name for dog is ____. animal, canine ---------------
Correct Answer
ion, positively, negatively, positive, negative, IonExplanation
Ionic compounds contain iron. They are not positively or negatively charged.Rate this question:
