Question

Dinitrogen momoxide(also called nitrogen oxide) is also called"laughing gas." It can be prepared by the thermal decomposition of ammonium nitrate. The other product is water. (a) Write a balanced equation for this reaction. (b) How many grams of dinitrogen monoxide are formed if .46 moles of ammonium nitrate is used in the reaction?

Answer 1

Dinitrogen monoxide(also called nitrogen oxide) is also called"laughing gas." It can be prepared by the thermal decomposition of ammonium nitrate. The other product is water. (a) Write a balanced equation for this reaction. (b) How many grams of dinitrogen monoxide are formed if .46 moles of ammonium nitrate is used in the reaction?

Solution:

(a) $NH_{4}NO_{3} = N_{2}O + 2H_{2}O$

Mr $(N_2O) = 14*2 + 16 = 44$

(b) $m(N_2O)(g) = 0.46*44 = 20.24$

Answer: 20.24 g
