Mole fraction is expressed as the number of moles of solute over the total number of moles of solute and the number of moles of solvent. When expressed in molal, this is equal to number of moles of solute per liter solvent. If the mole fraction is 1.00, this means, all that is in the solution is solute. Hence the molal equivalent is 1.00 too
The element that has the greatest attraction for sulfur electrons is I (Iodine)
B. 0.9 <span>
</span>D.Light intensity has no effect on whether electrons are emitted or not.
and
A. X=1.9eV,Y=0.2eV
I already took the gizmo so I know these are right. The first one I got wrong b/c there was no graph and the last one I didn't understand. Basically for the last one you calculate the work function for the metals and find their difference.
Hope this helps.
Looks like 3*.5 mol of N, or 1.5*.5 N2
<span>convert that to grams.</span>
When light breaks apart CO2, the molecule normally splits into carbon monoxide (CO) and an oxygen atom (O).
