how do you know if a reaction will take place or not
like i know that i have to use the activity series and all but isn't that only when the reaction thing is single displacement where there 1 element in the first thing and then 2 element in the second compound so like this (a+ bc= ac + b) so for example Zn(s) + 2HCl(aq) -> ZnCl2(aq) + H2(g) so this reaction occurs because Zn is more to the left of the activity series compared to H but my question is what if its a double displacement reaction so AB+ CD -> CB + AD
for example i have Na2S + H2O how would i kno if a reaction takes place or not?
or do i always assume that when there are 2 elements in each reactant/ compound, that a reaction will always occur?
srry if this question is kinda confusing
it's just that i don't know the correct chemistry terms to use
and also I am in grade 11 chemistry so please easy with the chem terms
