Answer the following questions.
What is chemical reaction Give an
example of each of exothermic and
endothermic reaction.
Answers
Answer:
An example of an exothermic reaction is the chemical reaction between sodium and chlorine, which results in the formation of sodium chloride (also known as common salt). The endothermic process is a term that describes a reaction where the system absorbs the energy from its surrounding in the form of heat.
Answer:
chemical reaction - a process that involves rearrangement of the molecular or ionic structure of a substance, as distinct from a change in physical form or a nuclear reaction.
Explanation:
example - endothermic - Melting ice cubes.
Melting solid salts.
Evaporating liquid water.
Converting frost to water vapor (melting, boiling, and evaporation, in general, are endothermic processes
exothermic - rusting of iron (rust steel wool with vinegar)
the thermite reaction.
reaction between water and calcium chloride.
reaction between sodium sulfite and bleach (dilute sodium hypochlorite)
reaction between potassium permanganate and glycerol.
