Both 2-methylheptane and 2,2,3,3-tetramethylbutane have C8H18. how can you tell which has a higher viscosity? They both have London force and I would assume it is based off of the shape. But...

If a student dissolves 5.082 g of NiCl2 * 6H2O in water in a 250.0 ml flask, what is the solutionâ€™s concentration in g/L? (show all work)  convert mL to L ml to L divide by 1000...

Hi all,     So my experiment with the waiting list was a mixed success.  I had some students remain interested when I contacted them as availability popped up later in the semester, but it was about 20% of the people. It was still a useful way to remain visible to students so I'm going to continue it.   I have room this Fall for another student or... read more

I was told to tell based on using if a molecule is polar non polar or having hydrogen bonds to determine electronegativity along with the total number of electrons   However when I got...

Wouldn't you set up the equation like this: 37.4 (1mol/159.65)(3mol/1mol)(28/1mol) I understand how to do the percent yield, I just can't figure out the mass to mass equation part
