Female Professor: Well, we know that the reaction that takes place is not chemical in nature. The color changes are executed by two different kinds of cells in the octopus's skin, mainly by color cells on the skin’s surface, called chromatophores.Chromatophores consist of tiny sacs filled ...
Because no chemical reaction takes place when a mixture is formed, no energy (e.g. heat, light or electrical energy) is released or absorbed during the formation of a mixture.Do mixtures consist of atoms or molecules ?Mixtures can consist of either atoms or molecules - but must include at...

What happens in the chemical reaction in which sucrose is heated? Sucrose: Sucrose is a disaccharide sugar that is commonly used as a sweetener in cooking and beverage preparation. It is made up of the monomers glucose and fructose, which are both six-carbon sugars. ...

Physical absorption— A non-reactive process e.g. when oxygen present in air dissolves in water. The process depends on the liquid and the gas, and on physical properties like solubility, temperature and pressure. Chemical absorption— A chemical reaction takes ...
the current structure of the economy: we take materials from the earth, make products from them, and eventually throw them away as waste. The foundation advocates a transition from this so-called linear economy to acircular economy, in which we stop waste being produced ...
which might be illustrated as a pipe ,e.g., the heat exchanger described earlier, with a homogeneous chemical reaction occurring in the fluid within .The fluid enters with a certain concentration of reactant and leaves the tube with a decreased concentration of reactant and an increased ...
