Are nodal planes related to nodes in the atom? I know that p, d, and f orbitals have nodal planes so does that contribute at all to the formation of nodes in an atom?

So if, for example, you get a value joules divided by kg, then that would leave you with m^2*s^-2. Hope that helps!

So my question is how to determine sig figs for adding scientific notation WHEN the powers of 10 are different for the two numbers. For example: 1.66 x 10^-17 + 5.9 x 10^-18 = 2.25 x 10^-17 (Problem Ch 1 #33) Solution guide says that it's three sig figs. Is it because you have to "adjust" ...

"When 0.528 g of sucrose is burned, 0.306 g of water and 0.815 g of carbon dioxide are formed. Deduce the empirical formula of sucrose." I was able to get to the point where I could divide by the smallest number of moles. When I divided the number of moles of carbon by that number, I got a...
