Describe how oxidation and reduction involve electrons, change oxidation numbers, and combine in
oxidation-reduction reactions.

Redox

Explanation:

Reduction is gain of electrons

oxidation is loss of electrons

Oxidation and reduction involve electrons because electrons are transferred and atoms either gain and lose electrons during these reactions to form ions. The charges of these newly formed ions are based on the number of electrons that are transferred during the reaction. The xidation number is decreased if electrons are gained and the oxidation number is increased if electrons are lost. In oxidation-reduction reactions, one atom can lose electrons while the other atom or atoms in the compound gain electrons to become oxidized. Similarly, an atom or atoms can gain electrons while the other atom or atoms can lose electrons to become reduced.

Explanation:

Just keep O  i  l  R  i  g in mind and redox (oxidation-reduction) reactions become simpler to understand. I promise. I hope this helps! Have a great day or night!!

Oxidation

is

loss

Reduction

is

gain

in scientific notation, the value of the  speed of light in a vacuum

  will be written as 2.995 * 10^8. when this value is represented in the form of

  a * 10^b, then, a = 2.995 and b = 8.

the value of the speed of light in a vacuum given above can also be rounded up to approximately 300000000. in this case, the scientific notation will be written as 3 *10^8.
