Nitrous oxide (N 2 O) can be produced by thermal decomposition of ammonium nitrate: NH 4 NO 3 ( s ) → heat N 2 O ( g ) + 2 H2O ( l ) What volume of N2O( g ) collected over water at a total pressure of 94.0 atm and 22°C can be produced from thermal decomposition of 2.6 g NH4NO3? The vapour pressure of water at 22°C is 21 torr.

The image compares the arrangement of electrons in two different neutral atoms. a figure labeled atom q has a shaded sphere at the center of three concentric circles. the innermost circle has two black spheres. the middle circle has six black spheres. to the left of this figure is another figure labeled atom p. atom p has a shaded sphere at the center of three concentric circles. the innermost circle has two black spheres. the middle circle has seven black spheres. which of the following best explains the position of the two atoms in the periodic table? atom p has an estimated zeff of 7 and is therefore to the left of atom q, which has a zeff of 6. atom p has an estimated zeff of 7 and is therefore to the right of atom q, which has a zeff of 6. atom p has an estimated zeff of 5 and is therefore below atom q, which has a zeff of 4. atom p has an estimated zeff of 5 and is therefore above atom q, which has a zeff of 4.
