In chemistry, a compound is a substance made up of two or more different chemicalelementscombined in a fixed ratio. When the elements come together, they react with each other and form chemical bonds that are difficult to break. These bonds form as a result of sharing or exchangingelectronsbe...

Copper chemistry is remarkably complex. Just to give you an idea, the chloride ions play an important role in this reaction. E.g. if you do the same with hydrogen peroxide and dilute sulphuric acid, then you'll see that the reaction is much slower. The special thing is that Cu2+ ...
Polyacrylic acid is a large-molecular-weight compound called a polymer, which consists of small repeating units called monomers. The polyacrylate polymer used in diapers is constructed from the acrylic acid and sodium acrylate monomers. The length of the polymer chain and the properties of the polym...
Chemistry class (Photo Credit : Elegant Solution/Shutterstock) When you see a molecular diagram or read a molecular formula, it may not immediately be apparent whether you are seeing a molecule or a compound. In fact, you may not even know if there is a difference between these two designati...
