chemistry home work help?

[BigFatCow]

its chemistry i have to predict the products of equations and balance them. i know how to balance but not how to predict.

number in () means sub script

1.Cu+ZnSO(4) = ?
2.O(2)+Fr=?

theres more but if you can tell me with how to do them i can do them myself.

 

[BigFatCow]

need help bad.

 

[BrunoPuntzJones]

put chemistry in the title

 

[carmeo]

Cu + ZnSO(4) -> CuSO(4) + Zn
O(2) + 4Fr -> 2Fr(2)O

anyone disagree?

 

[Moonbeam]

Are we really talking francium here or did you mean iron.

 

[BigFatCow]

francium

 

[Moonbeam]

carmeo says francium oxide, but I would suspect hydroxide would be more likely, but don't know for sure and hydrogen isn't part of your equasion.

On the other one I don't know if copper is more reactive and would replace zink, so I'll give you a bump.

 

[DannyLove]

i agree with carmeo

then again i failed CHM twice

danny~!

 

[NelsonMuntz]

<< Cu + ZnSO(4) -> CuSO(4) + Zn
O(2) + 4Fr -> 2Fr(2)O

anyone disagree? >>


This looks right to me. The first one is replacement and the second one is combination or something like that.
