Which phrase best defines a redox reaction?(1 point)
Responses
a reaction in which oxygen combines with different atoms
a reaction in which oxygen combines with different atoms
a reaction in which electrons are transferred between different atoms
a reaction in which electrons are transferred between different atoms
a reaction in which the number of oxygen atoms is reduced
a reaction in which the number of oxygen atoms is reduced
a reaction in which electrons are released from the system
a reaction in which electrons are released from the system
The correct answer is: a reaction in which electrons are transferred between different atoms.
To determine the correct answer, we need to understand the concept of redox reactions. Redox reactions, also known as oxidation-reduction reactions, involve the transfer of electrons between different atoms.
Option 1, "a reaction in which oxygen combines with different atoms," does not fully capture the essence of a redox reaction. While oxygen can be involved in redox reactions, it is not the defining characteristic.
Option 3, "a reaction in which the number of oxygen atoms is reduced," is not the best definition of a redox reaction. It focuses on the change in oxygen atoms rather than the transfer of electrons.
Option 4, "a reaction in which electrons are released from the system," is partially correct because redox reactions involve the transfer of electrons. However, it does not mention that electrons can also be gained by another atom in the process.
The most accurate definition is option 2, "a reaction in which electrons are transferred between different atoms." This definition encompasses the fundamental characteristic of redox reactions, which is the transfer of electrons.
