why so magical: every time i see people just write out the chemical reactants and their products. Say without remembering the formula: 1. how do you know the product that will be formed; such as what will bond with what? (example could work it out quickly by considering the valence of the reactants) 2. how do you know the charge of the ion or the ratio of the compound formed? ( is it also possible to determine the ion formed by considering the valences? Or is that something you have to remember) # going to fail the chemistry test this wednesday
Well maybe this is too late but for #1, there is the electronegativity. If one is higher than the other, it will take the lower's place. Also, there is a term called "Metal reactivity serie" that can be related to.
Completely inaccurate as rust is actually Ferric oxide with Fe+3 not Fe+2, and this creates confusion later when you reacted it with HCL and got FeCl2 when it should be FeCl3
as a student of mrs dreon she told me to say that iron oxide can be FeO, Fe2O3 and Fe3O4 can all be rust since irons a transition metal and has different numbers of valence electrons

Very bad
Shut up
i think you meant to comment “very good video”
