OMG the solubility chart! I've been wondering for weeks how my lecturer expects us to know a solid from a gas from a liquid - I didn't know such a chart existed until now.
Is it reasonable for them to expect us to know if something is s/l/g/aq without giving us this chart or telling us directly that a substance has been dissolved etc? (discounting the obvious diatomics and gases).
BTW your videos are *fantastic*, and have really helped me to get through my chem bridging course!

thank you so much! this helped alot
For the chart part...we used the activity series for single replacements, so I kinda got confused with that part, but we used the solubility chart for double replacements. So the a.series chart can be applied to single replacements as well, right?

how to you know the products formula when they reacts for example H2+N2-->NH3,how do you know that it is NH3 or something else? is it a way to determin it or just by memorizing them all?

When nonmetals react, you have to be told the product(s); when it's ionic compounds, you can predict with replacement reactions!
