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 combustion reactions produce water .So, we kn...

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 be a...

Sodium oxide has a formula of Na 2 O. Since sodium is a metal and oxygen is a non metal, sodium oxide is an ionic species. Sodium will lose an electron to form a cation and oxygen will gain 2 electrons to fo...

Graphene has strong covalent bonds between the carbon molecules giving graphene properties such as a high melting point and making it very strong.Due to the delocalised electrons that are free to move across...

HA <----> H+ + OH-Acid:Adding an acid increases the concentration of H+ ions as acids are proton donors. These H+ ions react with the conjugate base, A-, to form HA and thus shift the equilibrium posit...
