Chemistry Zinc and Copper question?

What experiment can you do to prove that Zn is not able to reduce Cu??


Anybody that tells you 1000 CC's is to much is wrong, anybody that tells you will wreck your first bike is wrong. I have been riding a couple of years, my first and only street bike was and is a 99 zx9r, I have never laid it down. Can the bike do 170, I am sure, I do not ride it like that, on the other hand the extra power has saved my *** for than once, anyone who's been riding long enough knows this. I am sure I will get a couple thumbs down from people who did not grow up riding and bought a bike they could not control and did not respect. The answer is, get a feel for what you want, and buy what you need. If you are going on the freeway a 250 is a death trap, you will need the power sooner or later. Take more than one Motorcycle safety course, even if you think it is boring and you know what you are doing. I always ride full gear any where I go, it's that short trip you don't wear the helmet that will get you. Just because you're bike can do a ten second quarter mile, does not mean you should ride it like that. Test drive a couple and see what is right for you, good luck and ride safe. It's the bullet you don't see that kills you.
It's always good to start small and as you start riding you will eventually get comfortable enough to upgrade. Only you will know when you're ready and comfortable. So it's a wise move on your behalf to start with the 250. As far as the you will grow out of it excuse a lot of new rider use, of course you will grow out of it if you didn't want it In the first place but it's still a good idea to start on one. I didn't want a 250 to begin with but I got one anyways just to learn on then when I was comfortable I moved on. And to the guy who started on the zx9r, yes it's very much possible to start on a busa even but for most people starting small helped them learn faster. I mean it is great that you learned on a large bike and didn't have to spend money on a 250 then more money on a larger bike once you got used to it. And also unless you ride the autobahn daily I don't see a situation where being able to exceed 100mph saved someone's life.
Actually, zinc is more reactive than copper and WILL reduce copper(II) ion to copper metal. To demonstrate this, go buy some copper and zinc plated nails from a hardware store, and some lemons from a grocery store. Put one of each nail into the lemon and connect a voltmeter to the two electrodes. You could also create several of these voltaic cells and connect them in series. The voltmeter will not only show the difference in potential, but also which nail is the anode and cathode. Zn + Cu?? -- Zn?? + Cu Anode (oxidation): Zn -- Zn?? + 2 e- Cathode (reduction): Cu?? + 2 e- -- Cu In reality, zinc is commonly used as a sacrificial anode in order to preserve other metals such as iron. For example, a zinc bar is often used on an outboard motor in order to protect the motor (made of steel) from corrosion.
I scares me to think that you have graduated high school and still think your rambling lack of grammar and spelling is an appropriate way to communicate. It also give me the idea, since you have no time to pause for punctuation, you will also live too fast and ride too fast. Take the beginners' riding class before you get your heart set on a bike. Look for a small used bike with the idea you will trade to a larger one after a few years of riding. A FEW YEARS! You are at the age that you are still getting experience driving a car. You have a young man's enthusiasm and sense of invulnerability. You need to watch out that. It would be nice if you made it past your teens. Many young men on big bikes do not.
