The mental and physical state of the smoker, and the situation in which smoking occurs, influence the way in which a cigarette affects psychological states and physiological responses.3. In order to provide a strong psychoactive reaction, nicotine must be delivered rapidly to the brain.
Redox Reactions Redox reactions, or oxidation-reduction reactions, have a number of similarities to acid-base reactions. Fundamentally, redox reactions are a family of reactions that are concerned with the transfer of electrons between species.
these reagents are also called as reductants redox reactions reactions which involve change in oxidation number of the interacting species problem 8 4 justify that the reaction 2cu2o s cu2s s 6cu s so2 g is a redox reactionnd the other half reaction is h2 g 2e 2 h g this splitting of the reaction under examination into two half reactions automatically reveals that here sodium is oxidised and hydrogen is reduced therefore the complete reaction is a redox change
