what is the difference between a chemical process and a chemical reaction?
311733
There is no difference. Chemical changes are also known as Chemical Reactions - a change that results in the formation of new chemical substances. At the molecular level, chemical change involves making or breaking of bonds between atoms. These changes are chemical - for example, iron rusts and iron oxide is formed.

Chemical changes happen when chemical reactions occur. They involve the formation of new chemical elements or compounds . Physical changes do not lead to new chemical substances forming. In a physical change, a substance simply changes physical state , eg from a solid to a liquid.

A chemical change results from a chemical reaction, while a physical change is when matter changes forms but not chemical identity. Examples of chemical changes are burning, cooking, rusting, and rotting.

(1) Nuclear reactions involve a change in an atom's nucleus, usually producing a different element. Chemical reactions, on the other hand, involve only a rearrangement of electrons and do not involve changes in the nuclei. ... (3) Rates of chemical reactions are influenced by temperature and catalysts.

Chemical reactions, on the other hand, involve only a rearrangement of electrons and do not involve changes in the nuclei. ... The nuclear chemistry of different isotopes vary greatly from each other.

Chemical reaction. A process during which chemical bonds between atoms are broken and new ones are formed. Producing one or more different substances. reactant. the starting materials in a chemical reaction.

The key difference between industrial chemistry and chemical engineering is that the industrial chemistry applies chemical and physical processes to convert raw materials into important products whereas the chemical engineering is a branch of engineering that designs the processes to produce, transform and transport ...

Chemical processes occur when bonds are broken and reformed. Physical processes occur when intermolecular forces are broken and reformed. A gray area exists between these processes which can be either chemical or physical.

When a chemical reaction occurs, energy is transferred to, or from, the surroundings. An exothermic reaction releases heat to the surroundings and an endothermic reaction absorbs heat from the surroundings.

A chemical reaction is the process in which atoms present in the starting substances rearrange to give new chemical combinations present in the substances formed by the reaction. These starting substances of a chemical reaction are called the reactants, and the new substances that result are called the products.

Reactants and Products in Chemical Reactions. In a chemical reaction, substances (elements and/or compounds) called reactants are changed into other substances (compounds and/or elements) called products. ... Instead, you create a new substance with chemical reactions.

A physical reaction occurs when molecules undergo a molecular rearrangement to produce a physical change. The molecules are not chemically altered. ... So, the difference is that with a physical reaction, a chemical change in the molecule is not observed, but a physical change is observed.

What is the difference between a chemical and physical change? Chemical changes involves the production of an entirely new substance through breaking and rearranging atoms. Physical changes are usually reversible and do not involve the creation of different elements or compounds.

The reaction rate or rate of reaction is the speed at which a chemical reaction takes place. We define reaction rate as the speed at which reactants are converted into products. ... Chemical kinetics is the part of physical chemistry that studies reaction rates.

Breaking and Making Chemical Bonds The reactants and products in a chemical reaction contain the same atoms, but they are rearranged during the reaction. As a result, the atoms end up in different combinations in the products. This makes the products new substances that are chemically different from the reactants.

Summary. A chemical property describes the ability of a substance to undergo a specific chemical change. A chemical reaction is a process that occurs when one or more substances are changed into one or more new substances.

During a chemical reaction, the reactants are used to make the products. The atoms in the reactants have been rearranged into new compounds (the products).
