What is the process that changes one set of chemicals into another set of chemicals quizlet?
a process that changes or transforms one set of chemicals into another. The elements or compounds that enter into a chemical reaction. The elements or compounds produced by a chemical reaction. Chemical reactions involve changes in the chemical bonds that join atoms into compounds.
What is the process that changes one set of chemicals into another set of chemicals by reorganizing the atoms and their bonds?
The process of reorganizing atoms by breaking one set of chemical bonds and forming a new set is known as a chemical reaction.
What is a catalyst in chemistry?
A catalyst is a substance that speeds up a chemical reaction, or lowers the temperature or pressure needed to start one, without itself being consumed during the reaction. Catalysis is the process of adding a catalyst to facilitate a reaction.
Why are combustion reactions used?
Many combustion reactions occur with a hydrocarbon, a compound made up solely of carbon and hydrogen. The products of the combustion of hydrocarbons are carbon dioxide and water. Many hydrocarbons are used as fuel because their combustion releases very large amounts of heat energy.
What is a synthesis reaction?
Synthesis reactions are reactions that occur when two different atoms or molecules interact to form a different molecule or compound. Most of the time, when a synthesis reaction occurs, energy is released and the reaction is exothermic.
What is atomic rearrangement?
A rearrangement reaction is a broad class of organic reactions where the carbon skeleton of a molecule is rearranged to give a structural isomer of the original molecule. Often a substituent moves from one atom to another atom in the same molecule, hence these reactions are usually intramolecular.
What is catalytic process?
Catalysis has been defined as the process by which chemical reaction rates are altered by the addition of a substance (the catalyst) that is not itself changed during the chemical reaction (ACS, 1996).
Which term describes the conversion of substances into different substances?
chemical reaction, a process in which one or more substances, the reactants, are converted to one or more different substances, the products.
What is combustion process?
Combustion is a chemical process in which a substance reacts rapidly with oxygen and gives off heat. The original substance is called the fuel, and the source of oxygen is called the oxidizer. The fuel can be a solid, liquid, or gas, although for airplane propulsion the fuel is usually a liquid.
What is combustion chemical reaction?
combustion, a chemical reaction between substances, usually including oxygen and usually accompanied by the generation of heat and light in the form of flame.
What is exchange chemical reaction?
Exchange reactions are those in which cations and anions that were partners in the reactants are interchanged in the products. In exchange reactions, the products must remain electrically neutral. It is this fact that allows you to easily predict the products of these reactions.
What is combustion in chemistry?
combustion, a chemical reaction between substances, usually including oxygen and usually accompanied by the generation of heat and light in the form of flame.
What is another word for rearrangement?

What is heterogeneous process?
heterogeneous reaction, any of a class of chemical reactions in which the reactants are components of two or more phases (solid and gas, solid and liquid, two immiscible liquids) or in which one or more reactants undergo chemical change at an interface, e.g., on the surface of a solid catalyst.
What’s the meaning of catalysis?
Definition of catalysis : a modification and especially increase in the rate of a chemical reaction induced by material unchanged chemically at the end of the reaction.
What is the other name of chemical reaction?
What is another word for chemical reaction?
| chain reaction | domino effect |
|---|---|
| vicious circle | causal nexus |
| series of events | cause and effect |
| chain of circumstances | concatenation of events |
| powder train | ripples in a pond |
What is chemical reaction of combustion?
A combustion reaction is a chemical reaction which a fuel undergoes oxidation by reacting with an oxidizing agent, resulting in the release of energy (usually in the form of heat).
Why is combustion a chemical change?
Combustion, however, starts with carbon, and oxygen C(s)+O2(g), and end up with carbon dioxide CO2(g) a completely different molecule – that's a chemical change. Was this answer helpful?
What is photochemical process?
A photochemical reaction is a chemical reaction triggered when light energy is absorbed by a substance's molecules. This response leads the molecules to experience a temporary excited state, thus altering their physical and chemical properties from the substance's initial molecule.
What is synthesis and decomposition?
Synthesis is the process of the formation of new bonds between reactants to form new products, whereas decomposition is the breaking of chemical bonds within reactants to form different products.
What is another name for an exchange reaction?
An exchange reaction will occur when ions in the solution form insoluble products, weak electrolytes, or nonelectrolytes. Because there is an exchange of ions, it is also known as an ion-exchange reaction (1-2). In an exchange reaction, the cation from the first reactant reacts with the anion from the second reactant.
What’s chemical synthesis?
Definition. Chemical synthesis is the process by which one or more chemical reactions are performed with the aim of converting a reactant or starting material into a product or multiple products.
What is a synonym for changing?
adjustment, advance, development, difference, diversity, innovation, modification, reversal, revision, revolution, shift, switch, transformation, transition, variation, turnaround, adjust, alter, diminish, evolve.
What is the meaning rearrangement?
Definition of rearrangement 1 : the act of rearranging something or someone or the state of being rearranged rearrangement of the furniture changes that will require some rearrangement of the schedule …
What is homogeneous chemical reaction?
homogeneous reaction, any of a class of chemical reactions that occur in a single phase (gaseous, liquid, or solid), one of two broad classes of reactions—homogeneous and heterogeneous—based on the physical state of the substances present.
What is the difference between H * * * * * * * * * * and heterogeneous catalysis?
Catalysis in which the reactants and catalyst are in same phase. ie., same physical state is known as homogeneous catalysis. Catalysis in which the reactants and catalyst are in same phase. ie., same physical state is known as Heterogeneous catalysis.
What is catalyst of change?
What Is a Change Catalyst? Also called a Change Champion, we define a Change Catalyst as someone who helps to guide, navigate, and accelerate the people side of change with key stakeholders.
What is a catalyst in a chemical reaction?
A catalyst is a substance that speeds up a chemical reaction, or lowers the temperature or pressure needed to start one, without itself being consumed during the reaction. Catalysis is the process of adding a catalyst to facilitate a reaction.
What is chemical change and chemical reaction?
In a chemical change, a new compound is formed but in a physical change, the substance changes its state of existence. Atoms or ions or molecules which react to form a new substance are called reactants; the new atoms or molecules formed are products. A chemical reaction follows the law of conservation of mass.
What is called photolysis?
Photolysis (also called photodissociation and photodecomposition) is a chemical reaction in which an inorganic chemical (or an organic chemical) is broken down by photons and is the interaction of one or more photons with one target molecule.
