Displacement order A metal can only displace another metal from a compound if it is located above it in the reactivity series. A displacement reaction happens when a more reactive metal (one that forms positive ions more easily) displaces a less reactive metal from a compound. Example: Magnesiu...
Carbon belongs to the group IVA elements series. Therefore, it has four electrons in its valence shell. Hydrogen is the first element in the periodic table that Hydrogen has only one electron in its valence shell. For a molecule, we add the number of valence electrons on each atom in the ...
Through a series of case studies, we establish a list of crucial research questions that provide a direction for future research in this field: What is the contribution of chloride binding to chloride transport? What is the path for chloride transport in concrete? How are our findings on ...
As shown in scheme 1, the hydrolysis reaction is an example of a sol-gel process and the side product is ethanol. The reaction proceeds via a series of condensation reactions that convert the TEOS molecule into a mineral-like solid via the formation of Si-O-Si linkages. Rates of this ...
Being able to re-package those products to order and have them on the loading dock ready for shipment in as little as 15 minutes after receiving an order is a small miracle of modern industry. Why spend so much effort on simple two-terminal components? The combinatorics of voltage and ...

-15 o c, sodium chloride is spread over the roads in order to lower the freezing point of water and prevent the build up of ice. if the temperatures are below 18 o c, calcium chloride is used instead of nacl to melt the ice on the roads. this is because cacl 2 dissociates into ...
In 2017, it was the 286th most commonly prescribed medication in the United States, with more than one million prescriptions. 1,6-Di(4 -chlorophenyldiguanido)hexane gluconate (Hibiclens)is the most effective of a series of antibacterial biguanides originallydeveloped in Great Britain. Biguanide...
In order to concentrate a solution, either more solute particles must be added or some solvent must be removed. If the solvent is nonvolatile, a solution may be concentrated by evaporating or boiling off solvent. Dilutionsare made by adding solvent to a more concentrated solution. It's common...
