I need help!!!

Where are each of the three particles located within the atom?

What are the first three quantum numbers for the electrons located in subshell 2s?

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.
