define
a) rancidity
b) corrosion
c) endothermic reaction
d) exothermic reaction
Answers
Answer:
a) rancidity
Rancidity generally is the complete or incomplete oxidation or hydrolysis of fats and oils when exposed to air, light, or moisture or by bacterial action, resulting in unpleasant taste and odor.
b) corrosion
Corrosion is a natural process that converts a refined metal into a more chemically-stable form such as oxide, hydroxide, or sulfide. It is the gradual destruction of materials (usually metals) by chemical and/or electrochemical reaction with their environment.
c) endothermic reaction
An endothermic process is any process which requires or absorbs energy from its surroundings, usually in the form of heat. It may be a chemical process, such as dissolving ammonium nitrate in water, or a physical process, such as the melting of ice cubes
d) exothermic reaction
An exothermic reaction is a chemical reaction that releases energy through light or heat. It is the opposite of an endothermic reaction. Expressed in a chemical equation: reactants → products + energy.
hope it helps ☺️
Answer:
a) rancidity= the condition produced by aerial oxidation of fats and oil maked by unpleasant smell and taste is called rancidity
b) = corrosion is a irreversible damage or distruction of living tissue and materials due to a chemical or electro chemical reaction. c) = the reaction in which heat is absorb. d) = the reaction in which heat is given our
