A chemical bond is a force which holds the atoms together. Therefore, during a chemical reaction, the bonds between atoms have to break so that the atoms can rearrange to form the products. New bonds form between the atoms in the product. Next we will look at a chemical reaction that has been used by humankind for centuries.

Be they liquid, gel or powder form, most of the drain cleaners you'll find on store shelves use strong chemicals, and they come in liquid, gel and powder forms. All chemical reactions involve moving electrons, and drain cleaners work by either taking or giving electrons to the clogging substance, generating heat in the process.

The reactions of matter whether occurring in natural processes or in the laboratories can be interpreted using another language of chemistry – the equation. A chemical reaction transforms one or more substances into a set of different substances. The substances that enter into a chemical reaction are called reactants and the substances formed are the products.

The rates at which reactants are consumed and products are formed during chemical reactions vary greatly. We can identify five factors that affect the rates of chemical reactions: the chemical nature of the reacting substances, the state of subdivision (one large lump versus many small particles) of the reactants, the temperature of the reactants, the concentration of the reactants, and the ...

Some chemistry teachers like to define a chemical process as any process that involves a chemical reaction and all other processes as physical processes. According to such teachers, things like burning fuels are chemical processes and things like dissolving salt in water or freezing water into ice are physical processes. But this distinction is ...

The nature of chemical reactions and physical properties of materials (e.g., reactive, corrosive, flammable) determine the design, features and construction of reactors. Multi-purpose reactors have external shells and internal coils which are filled with cooling water, steam or chemicals with special heat-transfer properties.

Its chemical formula is Ca(OCl2) C a ( O C l 2) with its chemical name as Calcium hypochlorite. 1. Preparation of Bleaching Powder. Bleaching powder is synthesized by the action of chlorine gas (produced from the chlor-alkali process) on dry slaked lime ( Ca(OH)2 C a ( O H) 2 ). 2.

Chemical reactions occur between an acid and an alkaline--baking powder or baking soda--forming gas pockets, which make the dough rise. Yeast fungus, when combined with warm water, begins to ferment the natural sugars and carbohydrates found in flour and other bread ingredients.

Process Engineers work in Process or Continuous Manufacturing – takes a formulation or recipe of ingredients and blends them together using a chemical reaction, heat, cold, fermentation, etc continuously or in a batch into a final product which is usually a liquid, powder, gas or solid. (Think turning milk into baby formula, oil refining, gasoline, plastic, shampoo, washing powder ...

This process is known as saponification, and is the method to manufacture soap. The slippery feel of bleach on skin is due to saponification of the skin oils and destruction of tissue! Mixing bleach with some other chemicals can be hazardous due to unwanted side-reactions.

Crystallization is a process that includes a variety of steps for solid isolation, such as cooling, evaporation, concentration, reaction precipitation, pH change precipitation, and solvent change precipitation. These actions are performed using a batch crystallizer, which is a modified batch reactor.
