Oxygen, food, shelter and also water
reactant elements and molecules are used in a chemical reaction, they are not mixed or combined or produced in a chemical reaction.
Molecules are formed by synthesis from elements; molecules are broken by chemical reactions.
Both atoms and molecules are the smallest bits of elements and compounds, respectively, that retain the chemical and physical characteristics of that substance. We also note that molecules are made up of atoms
No, enzymes are not called elements. Enzymes are biological molecules that act as catalysts to speed up chemical reactions in living organisms. Elements are the basic building blocks of matter, such as oxygen, carbon, and hydrogen.
Organic refers to compound of carbon.
Molecules are formed from chemical elements associated by chemical bonds.
Nutrients are chemical compounds; they contain molecules - and the molecules are formed from chemical elements.
Molecules are chemical entities formed from two or more elements associated by chemical bonds.
Elements are the simplest form of matter and are made up of atoms. Atoms are the basic building blocks of elements and combine to form molecules. Molecules are made up of two or more atoms bonded together. In the context of chemical composition, elements combine to form molecules through chemical reactions, creating different substances with unique properties.
reactant elements and molecules are used in a chemical reaction, they are not mixed or combined or produced in a chemical reaction.
New elements can by obtained only by nuclear reactions.New molecules can be obtained by chemical reactions.
The most important is the electronegativity of chemical elements.
The elements or molecules that participate in a chemical reaction and yield a product.
One defining characteristic of a chemical compound is the inclusion of two or more chemical elements. When atoms of those different elements bond in a fixed ratio, the resulting molecules constitute a chemical compound. Molecules of a single chemical element (such as O2) are not considered compounds.
Symbols are used for elements, when writing chemical compounds. These clearly show reactions between molecules. This is chemical bookkeeping.
