read the passage about a chemical reaction that causes a change in temperature. then, follow the instructions below. to clean their drain pipes, some people make a solution of baking soda and vinegar. baking soda, also known as sodium bicarbonate (nahco3), reacts with acetic acid (c2h4o2) in vinegar. when these substances combine, the solution becomes colder, and sodium acetate (nac2h3o2), water (h2o), and carbon dioxide gas (co2) form. the gas creates bubbles that help clean the inside of the pipes. select the true statement. this chemical reaction is exothermic. it converts chemical energy to thermal energy, which is released into the surroundings. this chemical reaction is endothermic. it absorbs thermal energy from the surroundings and converts that energy to chemical energy.

Answer

Brief Explanations:

En una reacción endotérmica, la temperatura del sistema disminuye porque absorbe energía térmica del entorno. En este caso, la solución se enfría cuando el bicarbonato de sodio reacciona con el ácido acético, lo que significa que la reacción está absorbiendo energía térmica del entorno, siendo una reacción endotérmica.

Answer:

This chemical reaction is endothermic. It absorbs thermal energy from the surroundings and converts that energy to chemical energy.
