The answer is chloroplast
This is the decomposition reaction, namely the reaction of photolysis.
2AgCl = 2Ag + Cl₂
General 'rule' - "like dissolves like". The solubility
of a solute in a solvent (that is, the extent of the mixing of the
solute and solvent species) depends on a balance between the natural
tendency for the solute and solvent species to mix and the tendency for a
system to have the lowest energy possible.
Hope this helps :p
Because its only representing the most stable isotope of that element but its considered the atomic mass and not average atomic mass
