Katrina Montoya · Answer 1

The correct answer is exothermic. An exothermic reaction is a reaction that releases heat, and therefore it transfers heat to the surroundings (in this case, the tube), making it warmer. Instead, in an endothermic reaction, the heat is absorbed by the reaction.

Raelynn Wu · Answer 2

Answer: exothermic

Explanation:

In an exothermic reaction, heat energy is released.

Because the test tube feels warmer than before the reaction, it means that the reaction released heat to warm the test tube and to raise its temperature.
