As you may know, ionic compounds are composed of electrostatic forces of attraction between oppositely charged ions. This means that there are no free moving ions in the compound, as they have all been bo...
atomic number shows the number of protonsand proton number = the number of electrons so the overall charge of an atom is neutral.
NaOH is an ionic compound with strong electrostatic attraction between the oppositely charged ions. This means the melting point is high, as the bonds ne...
Firstly, note that the reaction is complete burning. This means there is no carbon monoxide produce, only carbon dioxide.Secondly, we should know that all simple combusti...
Each carbon atom forms 3 (covalent) bonds with other carbon atoms. One electron is left to be free, or as we say de-localised, and therefore can move around freely. Therefore an electrical potential can b...
