25 i got the #1, just not #2 and #3. an industrial chemical company has opened a new plant that will produce ammonia (nh3). hydrogen and nitrogen gases are reacted to produce the ammonia. for the first batch of ammonia production, 475 g of nitrogen is reacted with excess hydrogen, and 397 g of ammonia are produced. • write the balanced equation for the formation of ammonia from hydrogen and nitrogen. 2nh3 • calculate the theoretical yield of ammonia. work must be shown to earn credit. • calculate the percent yield for the ammonia production. work must be shown to earn credit.

Answer :

Part 1 : Balanced reaction,

Part 2 : The theoretical yield of gas = 440.96 g

Part 3 : The % yield of ammonia is 90.03 %

Solution : Given,

Mass of = 475 g

Molar mass of = 28 g/mole

Molar mass of = 17 g/mole

Experimental yield of = 397 g

Answer for Part (1) :

The balanced chemical reaction is,

Answer for Part (2) :

First we have to calculate the moles of .

From the given reaction, we conclude that

1 moles of gas react to give 2 moles of gas

16.96 moles of gas react to give moles of gas

Now we have to calculate the mass of gas.

Therefore, the theoretical yield of gas = 440.96 g

Answer for Part (3) :

Formula used for percent yield :

Therefore, the % yield of ammonia is 90.03 %

the correct answer is:

a. formation of precipitation
