This is a catalyst
Catalyst is the substance that speeds up a chemical reaction without being consumed in the process.
When a substance donates a proton during a chemical reaction, that substance can be classified as an acid. This behavior is consistent with the Brønsted-Lowry definition of acids and bases, which defines acids as proton donors and bases as proton acceptors. Examples of common acids include hydrochloric acid (HCl) and sulfuric acid (H₂SO₄).
A chemical reaction is a process that involves the breaking and forming of chemical bonds between different molecules to create new substances with altered chemical properties. It is characterized by the rearrangement of atoms and energy changes associated with the reaction.
A substance's Atomic Number is its most distinguishing property. It defines and describes It's chemical properties.
A reaction that produces heat
Catalyst is the substance that speeds up a chemical reaction without being consumed in the process.
Compounds that form after a chemical reaction is complete are called products. The compounds they're made of are called reactants.
An acid is a substance that donates hydrogen ions in a chemical reaction, typically characterized by a pH less than 7.
One term that defines an acid is that it has high concentration of H+ (Hydrogen ions). Another term that defines an acid is that it has a high concentration.

It would depend on your definition of a chemical. A chemical is: "a substance produced by or used in a chemical process." And, water is a chemical because it is be used in chemical reactions such as neutralization, redox, etc. I believe what you're asking though is if water is a chemical substance: "a material with a definite chemical composition." Water is also a chemical composition because of its electron configuration in its valence shell which defines its chemical properties.
The chemical formula H2O represents the chemical composition of water, so it is describing a chemical property. Chemical properties involve the behavior of a substance in chemical reactions and its ability to form new substances. Physical properties, on the other hand, describe characteristics such as color, density, and boiling point.
The Brønsted-Lowry model defines acids as proton donors and bases as proton acceptors. A base is a substance that can accept a proton or donate an electron pair in a chemical reaction. This allows bases to neutralize acids and regulate pH levels in a system.
