Which of these phrases accurately describe disproportionation? Check all that apply. A single compound reacts with itself.

A single compound oxidizes and reduces a second compound.

A single compound is simultaneously oxidized and reduced.

A single compound is produced by the reaction of two ions.

A single compound acts as both the oxidizing agent and the reducing agent.

ANSWER: A, C,E on E2020

a non redox reaction occurs when there is not a transfer of electrons. for redox reactions, which are reduction-oxidation reactions, a change in the oxidation number occurs. elements that are reduced gain electrons, and elements that are oxidized lose electrons.

explanation:

false

because it does not have the potential to be entirely used up

it would be a gas formation

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.
