svet-max [94.6K]

Answer:

4 NH3 (g) + 5 O2 (g) → 4 NO (g) + 6 H2O (l)

This is an oxidation-reduction (redox) reaction:

4 N-III - 20 e- → 4 NII

(oxidation)

10 O0 + 20 e- → 10 O-II

(reduction)

NH3 is a reducing agent, O2 is an oxidizing agent.

Does anyone know how to do this??? Calculate the % yield
eimsori [14]

Answer:

Percentage Yield = 56.9% (to 3 significant figures)

Explanation:

Firstly you need to calculate the amount of moles of Na used. Moles = Mass/Mr, so moles of Na = 1.72x10^-3/23. This gets you 7.47826087x10^-5 moles.

The mole ratio of Na:Na2O is 2:1 so the moles of Na2O will be the moles of Na divided by 2. This gets you 3.739130435x10^-5 moles.

Mass = Moles x Mr

The Mr of Na2O = 62

Mass = 3.739130435x10^-5 x 62 = 2.31826087x10^-3g

Percentage Yield = (Actual Yield / Theoretical Yield) x 100

Percentage Yield = (1.32x10^-3 / 2.31826087x10^-3) x 100

Percentage Yield = 56.93923481%

Percentage Yield = 56.9% (to 3 significant figures)
