Answer:47.05% is the percent yield of nitrogen in the reaction.

Explanation:

heoretical yield of nitrogen gas = x

Moles of ammonia =

According to reaction,2 moles of ammonia gives 1 mol of nitrogen gas.

Then 2.3529 mol of ammonia will give:

of nitrogen gas

Mass of 1.1764 moles of nitrogen gas,x = 1.1764 mol × 28 g/mol=32.94 g

Experiential yield of nitrogen gas = 15.5 g

Percentage yield:

hope that help

The reaction na 3po 4( aq) 3 agno3( aq) → ag 3po 4( s) 3 nano 3( aq) is best classified as a(n):_____.

Ugo [173]

The reaction $Na_{3} PO_{4} ( aq) +3AgNO_{3} (aq)$ → $Ag_{3} PO_{4} ( aq) +3NaNO_{3} (aq)$ is best classified as double displacement reaction.

Those reaction in which two compounds react by exchanges of ions to form two new compounds is called double displacement reaction. The easiest way to identify double displacement reactions is to check to see whether the cations exchanged anions with each other or not . Always balanced chemical equation is used to determine.

There are three types of double displacement reaction which is given as,

Precipitation
Neutralization
Gas formation

The real world example of double displacement reaction is combining vinegar and baking soda to create homemade volcano.
