In chemistry reactants vs products
WebA reactant is a substance that is present at the start of a chemical reaction. The substance (s) to the right of the arrow are called products . A product is a substance that is present at the end of a chemical reaction. In the equation above, the zinc and sulfur are the reactants that chemically combine to form the zinc sulfide product.

In chemistry reactants vs products
Did you know?
WebIf there are more products than reactants, then it is endothermic, because more molecules are broken, and breaking bonds consumes heat. If there are more reactants than products, then it is exothermic, because more molecules are combined, and forming bonds releases heat. Obviously, chemical formulas containing only decomposition or synthesis ... WebYou can think of the reactants as the ingredients for preparing a meal and the products as the different dishes in that meal. With that in mind, let’s take a look at the chemical equation for photosynthesis: Sunlight + 6 CO 2 + 6 H 2 O → C 6 H 12 O 6 + 6 O 2. CO 2 = carbon dioxide. H 2 O = water. C 6 H 12 O 6 = glucose.
