If "yes" what would you observe\nWrite a chemical equation that describes your predicted observations

Yes.  If carried to the extreme, you would see the aluminum strip dissolve, copper metal precipitating, and the solution color will fade from blue to colorless.\n\n2Al + 3Cu(2+) ---> 2Al(3+) + 3 Cu

It is a chemical reaction.

Sounds good...I was able to picture it...watch your punctuation tho!! Good luck!

yes, you'll get hydrogen cyanide. you could perform the experiment in a gas chamber, but its quite dangerous

Get some Wintergreen lifesavers.\n\n(P.S. - this really belongs in the Chemistry group, not the Astronomy group)

Maybe!Just look and see.

I know my chem, but have never heard of it nor could I find it.\n\nPerhaps you mispelled it?  It should be described in your book if they're going to use it as a problem.

Well, which of those things wasn't actually seen? Observations are writing down what you see. Since there is no lable to see on the gas, the statement "The gas is Carbon Dioxide." is a conclusion, not something actually observed. The answer is 2.

If I'm not mistaken, try to calculate the prediction equation and use it to draw the regression line.\ny= a + bx

Tell you what you post your answers and I'll tell you if you're right!

If I understood what you meant I might know something...

Oh yeah! That would be so cool. But I don't know if there is actually a real formula for it. I love that's so raven. What about you?

Read the label. It should say.

Did you pay attention to the experiment?  Your hypothesis is what you think might happen.  In fact, you've already stated the hypothesis: \n"If the enzyme is boiled,it will become denatured and no longer function."\n\nThe discussion details what you think about the experiment and compares it to other knowledge.  It also tells why you got the results you did...it's basically an overview of the experiment and further research on why things did what they did.  \n\nI hope you have the results handy to refer to.

The models that already exist are good enough for most chemists maybe all. Developments in molecular orbital theory on the other hand would be welcome.

Do you mean results of an experimental study?

You saw WHAT is possible?
