The reactions of matter whether occurring in natural processes or in the laboratories can be interpreted using another language of chemistry the equation. The water in the first reaction is in a liquid form while in the second reaction it is in a gaseous form. Word Equations These describe a chemical reaction using words rather than elemental symbols and chemical formula.
Word equations They are useful as they allow chemists to communicate what happens in a chemical reaction. Products can be elements or compounds. You might be interested in.
