What type of energy is needed for chemical reactions?

  1. Heat

  2. Kinetic

  3. Potential

  4. Electromagnetic

The correct answer is: Heat

Chemical reactions require heat energy to break and form the bonds between atoms in order to create new compounds. Kinetic energy is the energy of motion, which is not directly involved in chemical reactions. Potential energy is stored energy, which may come into play during chemical reactions, but it is not the type of energy needed. Electromagnetic energy is a form of energy that includes light and radio waves, which are not directly involved in the chemical reactions themselves. Therefore, the only option that is directly involved in chemical reactions is heat energy.
