Step-by-Step Text Solution:1. Definition of Monomers: Monomers are the basic building blocks of polymers. They are small, simple molecules that can join together in a chemical reaction to form larger struct
that determines the stability of the emulsion. When the concentration of Promulgen D is low, there are fewer molecules adsorbed on the interface, the strength of the interface film is poor, and the formed emulsion is unstable. When the concentration of Promulgen D increases to a certain leve...

other flammable liquids are effective, including diesel, turpentine, and jet fuel. All alcohols work, including ethanol, methanol, and isopropanol. Sometimes detergent, motor oil, polystyrene foam, or rubber cement
On the contrary, it is important to use Milli-Q to prepare reagents to avoid to contaminate them with either organics molecules or inorganic ions dissolved in the water (e.g. when you prepare buffer solutions). A similar approach must be adopted when adding water during the preparation of ...
on the other hand, is a solid and hard mineral composed of natural bitumen. Its primary compounds, known as asphaltenes, consist of large molecules. The color of asphaltite ranges from dark brown to black. Unlike Natural Bitumen , it cannot be dissolved in naphtha solution, a derivative of ...
The problem whether natural rubber is a polymer with linear chain molecules has been solved.(=The problem is whether natural rubber is a polymer with linear chain molecules, and the problem has been solved.)天然橡胶是否是线型链状分子的聚合物,这个问题已经解决了。 I have no idea when she will...

While the sap of the rubber tree (Hevea brasiliensis) is biodegradable, the vulcanized natural rubber is cross-linked and persistent in the environment. The “new economy” bioplastics include “drop in” materials, which are essentially classic plastics made from a renewable resource, e.g., PE...
More specifically, metallic or metalloid elements are usually employed as precursors in the sol–gel process. Organometallic precursors include silane alkoxides, which are the main fundamental elements of the majority of sol–gel processes. These molecules have a general Si(OR)4 formula, where R ...
