Question

define redox reaction write two equation ? and define rancidity and corrtion ?

Answer 1

rancidity is a type of reaction with atmosphere for example when we cut an apple and leave for 5 minutes then the colour and smell of that apple changes

Answer 2

Redox reaction is reaction which involves both reduction reaction and oxidation reaction ZnO+C gives Zn +Co .the process of slowly heating up of a metal due to atmospheric gases that is Oxygen water acid , present in environment is called corrosion and the oxidation of oils or fats in food resulting by the smell and bad taste is called rancidity
