Answer to Question #248156 in General Chemistry for Mr. Lee

Question

The depletion of ozone (O3) in the stratosphere has been a matter of great concern among scientists in recent years. It is believed that ozone can react with nitric oxide (NO) that is discharged from the high altitude jet plane, the SST. The reaction is

O3+NO product> O2+NO2

If 0.740 g of O3 reacts with 0.670 g of NO, how many grams of NO2 will be produced? Which compound is the limiting reagent? Calculate the number of moles of the excess reagent remaining at the end of the reaction.

Answer 1

Molar mass of O₃= 48

0.74/48= 0.0154

Molar mass of NO= 30

0.67/30= 0.022

Molar mass of NO₂= 46

= 0.0154+0.022= 0.0376moles
