Responses

All of the energy from the reactants will be lost to the surroundings.
All of the energy from the reactants will be lost to the surroundings.

All of the energy from the reactants will remain in the system.
All of the energy from the reactants will remain in the system.

Some of the energy in the reactants will remain in them after the reaction, but some is lost to the surroundings.
Some of the energy in the reactants will remain in them after the reaction, but some is lost to the surroundings.

The energy found in the reactants remains in the system, and the reactants also take energy from the surroundings.

Answer 1

"The energy found in the reactants remains in the system, and the reactants also take energy from the surroundings."

Explanation: in an endothermic reaction the system absorbs heat from the surroundings, so the products end up with more internal energy than the reactants. Energy is not lost to the surroundings — additional energy is taken in.
