read the passage about a chemical reaction that causes a change in temperature. then, follow the instructions below. the most common type of cement in the world is portland cement, named after an area of england that has a lot of limestone. limestone is made up mostly of calcium carbonate (caco3). when calcium carbonate is heated, it breaks down into carbon dioxide (co2) and calcium oxide (cao), the main ingredient in portland cement. as the products form, the air around the reaction becomes cooler. 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 Explanation:

Exothermic reactions release heat to the surroundings, making them warmer. Endothermic reactions absorb heat from the surroundings, making them cooler. Since the air around the reaction becomes cooler, heat is being absorbed from the surroundings.

Answer:

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