Hi, Can someone tell me the steps on how to find the displacement in 3D? I am trying to solve the problem with given: seperate angles of two different vehicles from north, clockwise direction. magnitude of their distances from the origin. and the magnitude for elevation. there is an attached image. Thanks

hi what is the difference between impact distance and horizontal distance? thanks

Hi, I am trying to work on this problem, but I don't understand it. this is the problem: A compound of molar mass 229 contains only carbon, hydrogen,iodine, and sulfur, Analysis shows that a sample of thecompound contains 6 times as much carbon as hydrogen. bymass. Calculate the molecular formula of the compound. my solution is attached..I am stuck.. . Help please

I got the answer thank you...

He did not say anything. He briefly describe the topic then ask us to this.

I am really confuse now...

I got 0.09457 mol Cu 9.7889*10^-3 mol Zn then?

I found the moles of Cu and Zn.Then, I am stuck...

ok then after that...

So I need to subtract the Zn from Cu? Is the question asking for the atomic mass for Cu only?

2g?

I am stuck... I don't get it... Help

will the balance equation be Cu +Zn -> CuZn? then calculate moles for each elements?then?

Can someone tell me how to approach this problem. I don't need to see any solution. I just want to know the steps in solving this kind of problem. A 6.01 g sample of copper is contaminated with an additional 0.64g of zinc. Suppose an atomic mass measurement was performed on this sample. Do I have to create a balanced equation, and convert the values for moles?

this is not a homework question, I'm preparing for my exam...

Hi, How will I know whether a molecule is nonpolar or polar???? Also, why is it that, even though some of the molecules have polar bonds it can also be a nonpolar molecule????

Is it possible not to use the henry's law?

Hi, Why is the solubility of oxygen in blood greater than its solubility in pure water? I need to have an answer that relates to solubility, temperature and pressure. I read about Henry's law, but its not that clear to me because my teacher did not discuss Henry's law in class.
