Which one is a true statement about endothermic reactions? A. I need you from an outside source is continuously being added. B. Reaction container always feels hot. C. The reactants have less heat energy and the products. D. More heat is given off then it put into reaction

Your answer is B, the reaction container always feels hot.

Correct answer: "A. Energy from an outside source is continuously being added."

An endothermic reaction is a reaction that is characterised by the system absorbing energy from its surroundings. That energy is usually in heat form. For example, when mixing water with potassium chloride, this reaction will absorb heat and the container will feel cold - endothermic reaction.
