YOu need to google solubility rules, and the child needs to memorize those seven rules. And you need to ask him why hasn't he memorized them...I am fairly confident they have been taught in class. ARe they in his notes?
YOu need to focus on teaching your child, in at that age, on learning study/learning skills. When are you going to buckle down on teaching responsibility for this. I would wager he has no class notes, nor text notes.
See this: Here is the best study skills program around, including notetaking. Take a look at it. If you as a parent can discipline your child accept responsibility, and have the skills to learn on their own, you will have done that child a great favor. If you don't , what good is his parents really doing him? After chemistry,what then? Math? Social studies? It has to change. This question on this reaction is basic stuff, and he has missed it. Why?
Good luck.
Helping my child study. Are there any online guides that can help me teach how to predict the products of a reaction.
i.e. _ Ag(NO3)+ _ CaCl2 yields
Really want to be able to teach my child how to do this rather than have the answer.
Thanks
