which reaction is endothermic? exothermic? explain your answer

Energy is conserved in chemical reactions, so the total amount of energy in the universe at the end of a reaction is the same as it was before the reaction.

When a chemical reaction happens, energy is transferred to or from the surroundings. When energy is transferred to the surroundings, this is called an exothermic reaction, and the temperature of the surroundings increases. Examples of exothermic reactions include:

Answer:

ENDOTHERMIC PROCESSES AND REACTIONS

Melting ice cubes.

Melting solid salts.

Evaporating liquid water.

Converting frost to water vapor (melting, boiling, and evaporation, in general, are endothermic processes.

Making an anhydrous salt from a hydrate.

Forming a cation from an atom in the gas phase.

Splitting a gas molecule.

EXOTHERMIC PROCESSES AND REACTIONS
