You probably mean "what reaction releases energy," in which case, lots. Reactions that release energy into the environment are called exothermic reactions. An example of which would be mixing sodium (Na) and water (H2O) to form sodium hydroxide (NaOH), hydride (H2), and heat/energy.
2Na + 2H2O ---> 2NaOH + H2 + heat/energy

What reactants are capable of interacting to form products in a chemical reaction that must first overcome a thermodynamic barrier?
Fast moving reactant molecules or basically reactant molecules with a lot of kinetic energy.
What is the stored energy of plants called?
Sun is the main source of energy on earth,plants use this reactant energy & change into chemical energy by photosynthesis & store it in ATP.
What term refers to the difference between the energy of the transition state and the energy of the reactants?
The different in energy between the products and reactant is known as enthalpy of the reaction, or ∆Hreaction.
Where does the energy come from that is needed for an endothermic reaction the products or the reactants?
-The Productt/reactant solution -The envoriment when no solution is involved
A change in which energy is taken in?
endothermic change
In an endothermic reaction which has the lower energy?
Reactant
For each gram of reactant fusion produces energy than fission?
For each gram of reactant fusion produces more energy than fission.
Does an exothermic reation release energy into its surroundings and its products have more energy to the reactant?
Two different answers:Yes, an exothermic reaction releases energy into its surroundings No, its products do NOT have more energy than the reactant(s)
Where does the energy come from to make NADPHin the light reactant?
From the energy stored in light.
Is energy a reactant or product of the combustion reaction?
product
Which is one reactant used in photosynthesis to convert light energy into chemical energy?
carbon dioxide
What is one reactant used in photosynthesis to convert light energy into chemical energy?
carbon dioxide
What happens to the reaction rate when reactant particles are able to collide more often and with more energy?
The reaction rate increases when reactant particles are able to collide more often and with more energy.
For each gram of reactant what type of energy does fusion produces?
more
In respiration where do the five classes of vertebrates get each reactant from and how do they absorb it into their lungs?
Glucose is taken from food.Oxygen is taken through air
A reactant in photosynthesis?
I am not sure if this is a reactant but I know that if it isnt then the process it takes to get it has a reactant in it. ATP and NADPH. These are synthesized by the use of light energy which occur in the thylakoid membranes of the chloroplasts. I hope this helps.
How is matter and energy conserved in a chemical reaction?
The reactant's/reactants' energy is rarely every seen in the products.
