Question

water and ammonium nitrate (nh₄no₃) react in an endothermic reaction in a beaker. what would you expect to observe during this reaction? the beaker will get colder. the reaction will give off light. the products will be gaseous. the reactants will boil.

Explanation:

An endothermic reaction absorbs heat from the surroundings. In this case, the beaker is part of the surroundings. As heat is absorbed from the beaker by the reaction, the beaker's temperature will decrease, making it feel colder. There is no indication that the reaction will give off light, that the products will be gaseous, or that the reactants will boil.

Answer:

The beaker will get colder.
