Question

What is the balanced equation for copper and sulfuric acid, copper nitrate, copper and lead nitrate, zinc and sulfuric acid, zinc and copper nitrate, and zinc and lead nitrate. Please help!

Answer 1

I'm not sure which are the reactants and which are the products..

Answer 2

This is a lab we did at school and we had to put sulfuric acid, copper nitrate, and lead nitrate to three pieces of copper. Same for zinc. We have to write the equations for those. I am really confused. If you can't help it's ok.

Answer 3

Ohhhh.
So this was what it looked like?
sulfuric acid + copper
copper nitrate+copper
lead nitrate + copper
Then it's the same thing, except with zinc?

Answer 4

Yes and also for lead too, I forgot about that one.

Answer 5

Alrighty.
What do your equations look like for each of these? With the chemical symbols, and such.

Answer 6

I do not even get how to do these equations so if you help me with them. I don't if it's too much to ask for? They just put: Cu + H2SO4, CU + Cu(NO3)2, and Cu + Pb(NO3)2 and the same thing for zinc and lead on the worksheet. I'm sorry if it's too much

Answer 7

No, not at all.
Did anything happen with the copper and sulfuric acid? And did anything happen with the copper and lead nitrate?

Answer 8

As for Cu + Cu(NO3)2, nothing's supposed to happen.
I'm assuming you guys are doing single replacements. Do you know what those are? :)

Answer 9

Yes there were no reactions for those two and yes i know what single replacements are

Answer 10

If there were no reactions, then I believe your equations would be the same: Cu(s) + H2SO4 (aq) -> Cu + H2SO4
And same for the other two for copper.
No single replacements happened here, since copper's lower on the activity series than hydrogen and lead. And copper can't do anything with copper. So I think your copper equations are done there. :)

Answer 11

And after your answer you could write "no reaction."

Answer 12

And what about zinc because that was the only one that reacted?

Answer 13

Alrighty. What are your equations for zinc? :)

Answer 14

It's the same Zn + H2SO4, Zn + Cu(NO3)2, and Zn + Pb(NO3)2

Answer 15

Alrighty. These all should have reacted.
So you have single replacements here:

H2 + ZnSO4
Cu + Zn(NO3)2
Pb + Zn(NO3)2

Just check the charges on those to make sure they're all equal and match. See how zinc replaced hydrogen, copper, and lead?

Answer 16

Ok and yes. I get it now thank you so much!

Answer 17

You're welcome. I think you got the ones with lead, then?

Answer 18

Yes, they didn't react so they would stay the same, right?

Answer 19

Yep. :) I'm wondering why the lead and sulfuric acid didn't react though...I guess you could write:
H2 + PbSO4 (and make sure those charges add up), but you may have to write no reaction after it, because in your experiment, it didn't react. Same thing for copper.

Lead nitrate would definitely stay the same.

Answer 20

Ok and again thanks for your help!

Answer 21

No prob :)
