This was clear chemical reaction. The Potassium Chlorate reacted with Oxygen in a combustion reaction to change the chemical structure so that it was able to react with Silver Nitrate.
Well, it introduced atoms in this world and their functions. When the theory of atoms were created many more theory's came and we slowly figure out what the atoms do and what their functions are. The theory of an atom really surprised people because most of the people never knew the possibility of having living things inside of them.
Hope this helps.
Auto-ionization of water:
<span>HOH(l) </span>↔<span> H</span>⁺<span>(aq) + OH</span>⁻<span>(aq) </span>
<span>You might also see: </span>
<span>2HOH </span>↔<span> H</span>₃<span>O</span>⁺<span> + OH</span>⁻<span> .......... or ............ H</span>₂<span>O + H</span>₂<span>O </span>↔ <span>H</span>₃<span>O</span>⁺<span> + OH</span>⁻<span> </span>
C2H5NO2 , if you need the lweis structure let me know.
