Question

Vinegar and baking soda are mixed together in a beaker. A thermometer is used to determine the temperature before and after the reaction. If the temperature of the solution decreased, what kind of reaction took place?

Answer 1

Answer:

endothermic reaction

Explanation:

Endothermic reactions involve heat energy from the surrounding thus decreasing the temperature.

Answer 2

Endothermic change

Explanation:

Enthalpy changes are heat changes accompanying physical and chemical changes. There are two types of enthalpy changes: Endothermic change and exothermic change.

In an endothermic change, heat is absorbed from the surround and hence the surrounding becomes colder at the end of the change.

A change that leaves the reaction colder is an endothermic change.
