Question
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 to produce sodium acetate
(NaC2H3O2)
, water
(H2O)
, and carbon dioxide gas
(CO2)
. As the products form, thermal energy is absorbed from the surroundings and converted to chemical energy. The carbon dioxide gas creates bubbles that help clean the inside of the pipes.
Complete the statement.
does this become warmer or colder

The reaction between baking soda (sodium bicarbonate) and vinegar (acetic acid) is an endothermic reaction, meaning it absorbs thermal energy from the surroundings. Therefore, as the reaction occurs, the temperature of the surroundings becomes colder.
