Marks awarded for mention of outer most shells of electrons, shielding effects along side distance from nucleus of respective atoms as well as increased positive charge due to increased number of protons ...
The reactants adsorb to an active site on the surface of the catalyst. The active site places the reactants in an orientation that allows them to easily react. The reaction then occurs an...
Silicon dioxide (SiO2) has a macromolecular structure. This means that it forms thousands of covalent bonds between its silicon and oxygen subunits. Sulphur trioxide (SO3), meanwhile, has a simple covalen...
One anomalous property of water is that when in its solid phase (ice) it is less dense than when it's in its liquid phase. This arises because of the hydrogen bonding network that exists between water mol...
