I would use a whiteboard to show that the Carbon atom shares two pairs of electrons with each Oxygen molecule

Covalent bonding is between non-metal atoms and involved the sharing of electron pairs, whereas ionic bonding is between a metal and a non-metal and involves the transfer of an electron from the metal to ...

The forces between the iodine molecules are stronger compared to the ones between chlorine

This is because when the metals are heated (burned), their electrons can briefly 'jump' from lower energy electron shells to higher energy electron shells. This requires energy to happen, and light is not...

First you must calculate the moles of Mg that originally reacted. moles = mass/Mr moles=48/24 moles= 2 Molar ratio of Mg to MgCl2 is 1:1 Therefore 2 moles of MgCl2 were produced moles= mass/Mr mass= moles...
