Sodium chloride has a giant ionic lattice structure with ionic bonding. There are electrostatic forces of attraction between the Na⁺ ions and the Cl^- ions.

(a) Coal contains  Carbon (80%) Sulfur (9%) Oxygen (5%) Hydrogen (1%) other elements (5%) (b) Carbondioxide (CO2) Sulfurdioxide (SO2) Water  (H2O) (c)  Carbon dioxide: Global warming (green house effect) ...

There are a few reasons why percentage yield will never be 100%. This could be because other, unexpected reactions occur which don't produce the desired product, not all of the reactants are used in the r...

So both are examples of very strong bonding. These are strong bonds that are difficult to break. With covalent bonds, the electron are shared between atoms whereas in ionic bonds the electrons are 'taken'...

Fractional distillation works by using the fact that molecules of different sizes have different boiling points. Generally, the smaller a molecule, the lower its boiling point. When heating up a mixture o...
