A metallic bond is the electrostatic force of attraction between the positive metals ions and the delocalised electrons. The three main factors that affect the strength of a metallic bond are: the number ...

Warm and distill with acidified pottasium dichromate. Then test with tollens reagent. The acidified pottasium dichromate will have oxidised the primary alcohol to an aldehyde, which will form a silver mir...

In Chemistry we need to know the structures of the molecules we make and work with. We use spectroscopy to work out the shapes of these molecules. Mass spectrometry is one type of spectroscopy and weighs ...

Electrophilic Addition

Differences in size of an ionic lattice are directly linked to differences in how exothermic the lattice enthalpy of a salt is. 

Mg²⁺ has a smaller radius than Ca²⁺  and thus ...
