Every chemical reaction involves a change in energy because different substances hold different amounts of energy. During the reaction, bonds inside the substances that are reacting together must ...

Students recognize that a particular color change is a characteristic property of a substance and that a color change can also be used as evidence that a chemical reaction has occurred ... laundry ...

For any given chemical reaction to occur ... model could make predictions with only about five steps, taking about 0.4 seconds. These predictions don't need to be fed through a confidence model ...

If they collide with enough energy, bonds can break and new bonds can form in a chemical reaction. The reactants just sit there until energy is added with the flame. The added energy is enough to make ...
