will Zn react with NaNO3? why or why not?
thanks

No!, I think it has to do with charges, Zn has a charge of 2+, while Na1+, and NO3 (1-) charge. Thats the only thing that makes sense to me, I might be wrong!!

It will not react. Check the electronegativity series.

I don't see why would their respective electronegativities make them not react, to my knowledge Na is an alkali metal and therefore highly reactive,
plz be more specific

ok lets think about this..

Na+ and NO3- so they are good...they will form an ionic bond
Zn by itself...look at its hybridzation its [Ar]4s2, 3d10 it is full already so its a neutral charge....so it wouldnt react

Na is more reactive than Zn a and for this reason Zn will not displace Na. The electronegativity series or the activity series guides you in deciding which reactions will go and which will not.

why is Na more reactive than Ca and K?

why is Na more reactive than Ca and K?

Check your chem textbook or look at the link given.

The activity is Li>K>Ca>Na...

wait....

Ok I worded my question wrong. Why is Na less reactive than Ca and K?
