A blank burst in the sky, often associated with fireworks or explosions, is indeed the result of a chemical reaction. In fireworks, for example, the combustion of various chemicals produces gases and light, creating the visual display. The bright flash occurs when these chemicals react rapidly, releasing energy in the form of heat and light. This phenomenon is a spectacular demonstration of how chemical reactions can produce dramatic effects in our environment.
A blank reaction is a reaction only for testing, to establish a zero line, for calibration, etc.
a group of atoms bonded together, representing the smallest fundamental unit of a chemical compound that can take part in a chemical reaction.
Chemical processes store and release energy in the form of chemical bonds. This energy is either absorbed when bonds are formed or released when bonds are broken, resulting in various chemical reactions taking place.
Fireworks change chemical energy in the form of gunpowder into light, heat, and sound energy when ignited. The gunpowder in the fireworks undergoes a rapid chemical reaction, releasing energy in the form of a colorful display.
In a blank reaction, energy is absorbed from the surroundings, causing the surroundings to feel cooler. This is an endothermic reaction because energy is required for the reaction to occur. Examples include melting ice or mixing ammonium nitrate with water.
A reaction where energy is taken in.
A chemical reaction in which bonds are broken is usually associated with the absorption of energy in the form of heat. This is because breaking bonds requires energy input to overcome the forces holding atoms together.
The coubustion of gasoline is an example of energy released by chemical changes
Metathesis.

activation energy
The process in which energy is given off is called an exothermic change. The energy released can be in the form of heat, light, electricity, or sound
A blank reaction is a reaction only for testing, to establish a zero line, for calibration, etc.
Enzymes are the substances that speed up chemical reactions in the body by lowering the activation energy needed for the reaction to occur. They are biological catalysts that help facilitate various cellular processes.
A solid formed from liquid reactants during a chemical reaction is called a precipitate. This occurs when two soluble reactants mix and a solid compound is formed that is insoluble in the reaction medium.
