Compounds that are gases at room temperature are covalent bonds (nonmetal + nonmetal).
1.53 mole of n2o2.
now just multiply 1.53 by avogadro's number.
1.53 x 6.02 x 10^23 = 9.21 x 10^23
that is your answer in scientific notation
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.
