Which identifies an oxidation reduction reaction

a. double replacement reaction
b. neutralization reaction
c. reaction which oxidation numbers change
d. reaction in which no electrons are transferred

The correct option is C.

Oxidation reduction reaction refers to a type of chemical reaction in which electrons are transfer between two species. The chemical species that are involved in the reaction always experience change in oxidation number as a result of gaining or losing electrons. Oxidation and reduction can be defined in several ways. In term of oxygen transfer, oxidation means gain of oxygen while reduction means loss of oxygen.

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
