In my class, my teacher asks about the colour of solutions after reactions and I never seem to understand from where my classmates know the answers. Is there some rule which I can follow, or is it something I just have to learn them from the internet?

14. complete and balance the equations for the single displacement reactions. a. zn + pb(no3)2 -> b. al + niso4 -> 15. complete and balance the equations for the double displacement reactions. a. agno3(aq) + nacl(aq) -> b. mg(no3)2(aq) + koh(aq) -> 16. complete and balance the equations for the combustion reactions. a. __ ch4 + o2 -> b. __ c3h6 + o2 -> c. + o2 ->
