Which of the following indicates that an endothermic reaction has occurred? Heat is released
Water is formed
Salt is produced
Temperature decreases

ive seen people say that its A but I don't think so because heat is released when its an exothermic reaction not an endothermic.
will mark brainiest if you get it right

Temperature decreases

Explanation:

The correct answer that indicates that an endothermic reaction has occurred would be a reaction in which the temperature decreases.

An endothermic reaction is a reaction in which energy in the form of heat is absorbed from the surrounding. Hence, the final temperature of an endothermic reaction is usually lower than the initial temperature.

Endothermic reactions are the complete opposite of exothermic reactions in which heat is given off in the course of the reactions. Hence, the temperature of the reaction in exothermic reactions increases instead of decreasing.

In summary, a decrease in temperature of a reaction is an indication that heat has been absorbed during the course of the reaction and such a reaction is said to be endothermic.

the answer is the first option

just googled it m8. not that hard
