An exothermic reaction is a chemical reaction that releases energy in the form of heat. This means that the products have lower energy than the reactants. Exothermic reactions are often characterized by temperature increases, light emission, or sound production.
A reaction that produces heat
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.
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.
Solubility is the term that defines the maximum amount of a solute that can dissolve in a solvent at a specific temperature and pressure.
A reaction that produces heat
An endothermic reaction need heat to begin.
This is a catalyst
Compounds that form after a chemical reaction is complete are called products. The compounds they're made of are called reactants.
A reaction that produces heat
Catalyst is the substance that speeds up a chemical reaction without being consumed in the process.
Action (gasses coming out of the rocket motor) will equal reaction (rocket being pushed)
An acid is a substance that donates hydrogen ions in a chemical reaction, typically characterized by a pH less than 7.
That defines addiction.
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.
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.
