The visible light emitted by a chemical reaction is a type of luminescence known as chemiluminescence. It occurs when a chemical reaction produces light as a byproduct, typically as a result of excited molecules releasing energy in the form of photons in the visible range. Chemiluminescence is commonly seen in glow sticks and fireflies.

What is the scientific word for a gas given off during a chemical reaction?
A reaction that emmits heat is called an exothermic reaction .
What is the name given to the substances at the start of a reaction?
The substances at the start of a chemical reaction are known as reactants. Reactants are the molecules or compounds that undergo a chemical change during the reaction. They are typically written on the left side of a chemical equation, while the products of the reaction are written on the right side. The reactants are consumed during the reaction to form the products.
What type of reaction is shown in following chemical equation NH3 HCL NH4CL?
The given chemical equation shows a neutralization reaction. In this reaction, an acid (HCl) reacts with a base (NH3) to form a salt (NH4Cl) and water.
An indication that energy is given off in a chemical reaction is shown by an?
An indication that energy is given off in a chemical reaction is shown by an increase in temperature. This is because the released energy can manifest as heat, causing the surroundings to become warmer.
What are the compounds on the left side of a reaction?
The compounds on the left side of a chemical reaction are the reactants. Reactants are the substances that undergo change in a chemical reaction to form products.
Why is it a sign of a chemical reaction if gas is given off?
It is sign of chemical reaction because smell and heat is produced.
