What is chemical reaction? - Great teacher!!

A chemical reaction is a reaction where there is a rearrangement or combination of electrons, or a change in structure. For example, the conversion of graphite into diamond is a chemical reaction because the structure of carbon changes from linear to crystalline. Redox reactions are chemical reactions because electrons are transferred.

How rubber cement is made - material, making, history

Rubber cement is a solution of unvulcanized (gum) rubber in a solvent, and is used as an adhesive. Ideally, it is meant to join two pieces of rubber together, which involves a chemical cohesion process. When joining two pieces of rubber, only one surface has to be coated with rubber cement since they are the same material.

What is Viscosity, and Why is Measuring Viscosity Important?

The formula for measuring viscosity is fairly simple: viscosity = shear stress / shear rate. The result is typically expressed in centipoise (cP), which is the equivalent of 1 mPa s (millipascal second). Shear stress is the force per unit area required to move one layer of fluid in relation to another.
