From the energy stored in light.
The breaking of covalent bonds requires the input of energy. This energy can come from various sources such as heat, light, or electricity.
Identifying the limiting reactant allows you to determine which reactant will be completely consumed first, thereby limiting the amount of product that can be formed. This information is crucial for calculating the maximum amount of product that can be produced in a reaction, ensuring efficient use of reactants.
The heat and light produced when burning propane come from the chemical reaction between propane and oxygen. This reaction releases energy in the form of heat and light as the propane molecules break apart and combine with oxygen to form carbon dioxide and water vapor.
The energy in an unburned match comes from the potential energy stored in the chemical bonds of the match head or the striking surface. This potential energy is released in the form of heat and light when the match is ignited and the chemical reaction takes place.
Bond formation releases energy in chemical reactions because when atoms come together to form bonds, they release energy that was stored in their chemical bonds. This energy is released as heat or light, making the reaction exothermic.

The heat energy and light energy of a candle come from the chemical reaction of the candle wax (hydrocarbons) combining with oxygen from the air. This reaction releases energy in the form of heat and light. The heat energy is produced when the chemical bonds are broken and reformed, while the light energy is generated by the incandescence of the soot particles in the flame.
