How are coefficients used in writing chemical equations?
They indicate the number of molecules in a substance.
What are codes used in chemical equations telling what atoms are part of the equations?
formulas
Does a chemical formula describes a chemical reaction?
Yes, chemical equations describe chemical reactions. A chemical equation tells you what substances are reacting, what substances are produced and, in a balanced equation, provides the coefficients to tell us in what ratio the substances react or are produced.
Why chemical equations used then writing chemical reactions sentences?
It is more simple and practical.
Chemical are codes used in chemical equations?
1. The representation of chemicals in chemical equations is made by formulas.2. The word code has another sense in chemistry; as an example, the digital code of the American Chemical Society - Chemical Abstract Service (CAS No).
