Oxide is a simple radical.

the oxygenmolecule(02or0-0) its self is free redicles or a-b redical whith two unpaired electrons that is electron configuration of the molecule has two unpaired electros occupying two degenerate molecular or bitals with the same spin orientation(up-upordown-dowan

Explanation:

in the lower atomsphere important redical are produced by the photodissociation if nitrogen dioxide to an oxygen atom and nitric oxide

True. Oxide is a simple radical.

Explanation:

Because it is. Brainliest PLZ.

answer: c. the experiment shows that the red substance experienced a chemical change.

explanation: chemical change is the change in which chemical composition of the substance changes. physical change is the change in which there is no change in chemical composition.

chemical changes are accompanied by following changes:

a) precipitate formation

b) energy is released or absorbed

c) formation of bubbles

d) change in color

as it is given that the red color has disappeared and there is production of gas, it means the red substance has undergone a chemical change.
