Students explore the concept that chemical reactions involve the breaking of bonds between atoms in the reactants, and the rearrangement and rebonding of these atoms to make the products. Students ...

The substances that are involved in a chemical reaction and that are changed by it are called reactants. The substances that are produced by a chemical reaction are called products. Chemical ...

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 ...

Heterogeneous catalysts speed up chemical reactions by being in a different state than the reactants. They are efficient and ...

The atom economy of a chemical reaction is a measure of the percentage of reactants that become useful products. Inefficient, wasteful processes have low atom economies. Efficient processes have ...

Transition metals have long been used as catalysts to activate small molecules and turn them into valuable products. However, as these metals can be expensive and less abundant, scientists are ...

Heterogeneous catalysts speed up chemical reactions by being in a different state than the reactants. They are efficient and stable, even under ...

Nanocatalysts function by providing a platform for reactants to come together more efficiently during chemical reactions. Their nanoscale size allows for a dramatic increase in the surface area ...
