For the reaction NH4NO3 (s) → N2O (g) + 2H2O (l), You decompose 1 mole of NH4NO3 and only get 0.7 moles of N20. What is the percent yield?
90%
25%
65%
70%

70% is the percent yield

Explanation:

First of all, we work with the stoichiometry of the decomposition:

NH₄NO₃ (s) → N₂O (g) + 2H₂O (l)

1 mol of ammonium nitrate can produce 1 mol of nitrogen oxide.

This, will happen with the 100% yield reaction.

To determine the percent yield we do:

(moles produced / theoretical yield) . 100 =

(0.7 moles / 1 mol) . 100 = 70%

the ozone layer acts as a filter for the shorter wavelength and highly hazardous ultraviolet radiation (uvr) from the sun, protecting life on earth from its potentially harmful effects. when the sky is clear, there is an inverse relationship between stratospheric ozone and solar uvr measured at the earth's surface.
