I don;t understand why the AlPO4 becomes a solid. I know based on solubility rules that all phosphates are insoluble" it forms a solid because it is insoluble "based on the solubility rules all carbonates are insoluble... Why is it that in the 1st equation it becomes a solid' it is a solid because it is insoluble "do I assume aluminum is soluble or insoluble" If it bonds with a group such as phosphates, it will be insoluble meaning it will precipitate "how do you know whether a precipate is a solid or aqueous in a reaction?" A precipitate is by definition an insoluble solid that forms from a reaction.
Lets take an example: MnCl2 (aq) + (NH4)2CO3 (aq) ---> MnCO3 (s) + 2 NH4Cl (aq) In this equation, we have two soluble ionic compounds: this means they'll dissociate into their respective ions: In water we get: (ignoring proper ratios): Mn 2 Cl - NH4 CO3 2- We have all of these species just floating around in the water, not actually bonded to anything. If Mn and Cl bump into each other, they will feel a slight attraction (positive and negatives attract), but they'll be quickly separated by water molecules.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
