A chemical reaction begins with a substance called and ends with substance called?
Pure substances (or ELEMENTS) form COMPOUNDS after a chemical reaction. For example: Sodium and chlorine, when fused in a chemical reaction become the compound Sodium-Chloride The substance you have in the beginning of a chemical reaction are called reactants and the substance you have when chemical reaction is complete is called products.
What is a chemical reaction and how are reactants and products involved?
A chemical reaction is a change in which one kind of matter changes into a different kind of matter with different properties. Reactant is a substance used in a chemical reaction and a product is a substance made in a chemical reaction. Hope this is helpful! ;)
What information is contained in a chemical equation?
A chemical formula contains information on the types and spatial arrangement of bonds in the chemical.It also tells you what elements are in the chemical, and how many atoms of each. The spatial arrangement is not necessarily very obvious from the formula, e.g. C2H5OH does not tell you much about the spatial arrangement of the bonds.A chemical formula uses symbols and numbers o represent the composition of a pure substance
