Question

Give an example of chemical reaction which take place with fall in temperature.

Answer 1

Answer:

two substances react and the temperature of the mixture decreases, the reaction is endothermic. If two substances react and the temperature of the mixture increases, the reaction is exothermic. A chemical reaction involves the breaking of bonds in the reactants and the forming of bonds in the products.

Baking soda reacts with the vinegar to produce carbon dioxide gas, sodium acetate, and water. ... Since more energy was needed to break the baking soda and vinegar apart, the temperature went down. This reaction is called an endothermic reaction.
