How can i find out how many moles I collected if i wasnt even given how many i started of with. I am sorry to sound dumb but I am having a difficult with this. It might be that I am just missing something really small.
Homework Statement
Given the following chemical reaction:
Zn + HCl ----> ZnCl2 + H2(g)
If you measured the total volume of collected gas over water at 20 Celsius to be 428 ml at a total pressure of 845 torr, how many milliliters of 2.6M HCl would be required to produce the correct amount of...
Thing is we haven't even gotten to work functions so I have to get the answer just using what i have. Ionization Energy of Nickel which is 757kj/mole Then i just factored it down to joules.
757(1000J/1KJ)(1mole/6.022e23)= 1.257J
ET=Total Energy
IE=Ionization Energy
KE= Kinetic Energy...
Homework Statement
Q. How much energy will it take to remove only one electron on the surface of Nickle? If you hit the surface of Nickel with a photon that has a wavelength of 90 nm, what will the wavelength of that ejected electron be?
Homework Equations
KE= 1/2 MV^2
\lambda=h/mv...
