Which of the following elements would you expect to have the lowest ionization energy value? fluorine, lithium, neon, nitrogen

How do scientists think that gravity affected the formation of our solar system?

For the reaction c6h14(g) & longrightarrow; c6h6(g) + 4h2(g), δp(h2)/δt was found to be 2.5 x 10-2 atm/s, where δp(h2) is the change in pressure of hydrogen. determine δp(c6h14)/δt for this reaction at the same time.
