Writing Chemical Equations. When sulfur dioxide is added to oxygen, sulfur trioxide is produced. Sulfur dioxide and oxygen, SO 2 + O 2, are reactants and sulfur trioxide, SO 3, is the product. 2SO 2(g) + O 2(g) ⏟ Reactants → 2SO 3(g) ⏟ Products. In chemical reactions, the reactants are found before the symbol " → " and the products …

Hydrogen Production. Hydrogen Production Processes. Hydrogen can be produced using a number of different processes. Thermochemical processes use heat and chemical reactions to release hydrogen from organic materials, such as fossil fuels and biomass, or from materials like water. Water (H 2 O) can also be split into hydrogen (H 2) and oxygen …

Chemical Etching Process. The chemical etching process involves selective material removal from a substrate using a chemical solution. The process begins with preparing the substrate, followed by applying a photoresist layer, exposure, development of the photoresist, etching, and finally, removal of the photoresist.
