Question

How would i do single replace ment for Zn+AgNo3->

Answer 1

When you look at the reactivity series, you notice that zinc(zn) is more reactive than silver(Ag) therefore zinc will displace Ag from AgNO3 and form Zn(NO3)2.
Zn + 2AgNO3 -> Zn(NO3)2(aq) + 2Ag(s)

Answer 2

Thank you now i have a question where did you get the 2 from sorry im really confused with this class

Answer 3

I just knew how to balance chemical equations and the reactivity series
