Group 18 noble gases are relatively inert because * their s and p orbitals are filled (outer energy level is filled).
they can have either a positive or a negative charge.
their outermost energy level is missing one electron.
they readily form positive ions.

For the reaction shown, calculate how many moles of no2 form when each of the following completely reacts. 2n2o5(g)→4no2(g)+o2(g) part a 1.0 mol n2o5 express your answer using two significant figures. nothing mol m o l request answer part b 5.4 mol n2o5 express your answer using two significant figures.
