What are endothermic reatcions?

Answer 1

Endothermic reactions are reactions in which the reactants have less energy than the products. This means that the reactants will require heat, in order for a reaction to take place. After an endothermic reaction occurs, the surrounding area around the reaction will feel cooler.

examples are 1) electrolysis.

2) thermal decomposition of calcium carbonate in a furnace.

3) the reaction of ethanoic acid and sodium carbonate.

Answer 2

Endothermic reactions absorb heat from the surroundings to proceed. This results in a decrease in temperature of the surroundings. Examples include photosynthesis, melting ice, and baking bread.
