Definition of chemical reaction in English: chemical reactionnoun A process that involves rearrangement of the molecular or ionic structure of a substance, as distinct from a change in physical form or a nuclear reaction. Example sentencesExamples - They each have different chemical reactions because of their molecular structure.
- A burning cigarette is a complex system in which many types of chemical reactions and physical processes occur in parallel.
- An exothermic reaction is a chemical reaction which produces heat.
- The fuel cell generates electricity as a by-product of a chemical reaction involving dilute methanol.
- It was undergoing a chemical reaction and increasing the carbon dioxide.
- But what happens to a chemical reaction if the reagents are not in an ideal ratio?
- Atoms of these elements have six valence electrons and tend to gain or acquire electrons in chemical reactions.
- They are catalysts that either begin chemical reactions or speed up chemical reactions already in progress.
- The energy involved in a chemical reaction can be related to the differences in energy between the reactants and products.
- The heat triggers a chemical reaction that turns the polymers into a hard, incredibly sturdy structure.
- Enthalpy is more useful to chemists than energy when measuring the heat involved in chemical reactions.
- The arrow in a chemical equation represents the process of the chemical reaction.
- The state of matter may affect the way in which the molecule takes part in a chemical reaction.
- Soaps are created by the chemical reaction of a fatty acid with an alkali metal hydroxide.
- Temperature can determine which ions can form or remain stable enough to enter into chemical reactions.
- His was the first group to study chemical reactions in this way under molecular beam conditions.
- Most possess only the vaguest understanding of molecules, chemical reactions, and research methods.
- Energy is not only involved in chemical reactions and technology, but also in our basic bodily functions.
- This is what scientists call a physical process, because no chemical reactions take place.
- Liquid ammonia is also utilized as a solvent in certain chemical reactions.
