Question

you hold a beaker in your hands as a chemical reaction occurs. the beaker gets warm to the touch as the reaction progresses. based on this observation, you might guess that the reaction is (1 point)
endothermic
exothermic
hexothermic
isothermic

Explanation:

Exothermic reactions release heat. Since the beaker gets warm, heat is being released, indicating an exothermic reaction. Endothermic reactions absorb heat, hexothermic is not a real - term in thermochemistry, and isothermic reactions occur at a constant temperature without heat release or absorption related to the reaction itself.

Answer:

B. Exothermic
