1. If 3.00g of ammonia reacts with 40.00g of oxygen, what is the theoretical yield of nitrogen monoxide?
2. If only 10.00g of nitrogen monoxide was isolated from the products, what was the percent yield of nitrogen monoxide?

The theoretical yield of nitrogen monoxide = 5.28 grams

Explanation:

Step 1: Data given

Mass of ammonia = 3.00 grams

Molar mass NH3 = 17.03 g/mol

mass of oxygen = 40.00 grams

Molar mass O2 = 32.0 g/mol

Step 2: The balanced equation

4NH3 + 5O2 →  4NO + 6H2O

Step 3: Calculate moles

Moles = mass / molar mass

Moles NH3 = 3.00 grams / 17.02 g/mol

Moles NH3 = 0.176 moles

Moles O2 = 40.00 grams / 32.0 g/mol

Moles O2 = 1.25 moles

Step 4: Calculate limiting reactant

For 4 moles NH3 we need 5 moles O2 to produce 4 moles NO and 6 moles H2O

NH3 is the limiting reactant. It will completely be consumed (0.176 moles)

O2 is in excess. There will react 5/4 * 0.176 = 0.220 moles

There will remain 1.25 - 0.22 = 1.03 moles

Step 5: Calculate moles NO

For 4 moles NH3 we need 5 moles O2 to produce 4 moles NO and 6 moles H2O

For 0.176 moles NH3 we'll have 0.176 moles NO

Step 6: Calculate theoretical yield of NO

Mass NO = moles NO * molar mass NO

Mass NO = 0.176 moles * 30.01 g/mol

Mass NO = 5.28 grams

Step 7: Calculate percent yield

% yield = (10.00 grams / 5.28 grams) *100 %

% yield = 189 %

⇒ Since the theoretical yield is less than 10.0 grams. I think the data are not correct ( may be 30.00 grams of NH3)

when—without warning—something provokes your anger, you may struggle not to succumb to it. since what typically makes you mad is feeling powerless in the face of what seems unfair, your anger is mostly an attempt at a “quick fix” to right the balance. it’s as though you’re raising a fist in protest, proclaiming that you’re not going to capitulate to such injustice.

there are, however, a multitude of problems related to this immediate, push-back reaction of anger. and probably the key one is that almost never does it resolve the issue that gave rise to it. such reactive anger is probably best understood as self-defeating. as david burns, the author of the seminal self- book feeling good, observes: if realistically, acting on your anger is to make any sense, it needs to meet two criteria—which, in almost every case, is frankly impossible. that is, your anger must:

be directed toward a person who has intentionally (and needlessly) behaved in a hurtful way toward you; and

be beneficial or advantageous to you (i.e., assist you in achieving a desired goal).

i think you’ll agree that only rarely can you claim that your anger is both warranted and , whether to yourself or the relationship.

so let me offer you a two-step alternative to abandoning your better judgment and giving in to the temptation of anger—one that should neutralize your anger in seconds. or, when you’re really angry, in minutes.

but keep in mind that you must really want to execute these steps, be sufficiently motivated to perform them. which means overcoming more unconscious resistance than you might ever have imagined. because there are many immediate “advantages” of anger that can interfere with your resolve, i’ll suggest a few of them that might interfere with your employing this powerful method to rid yourself of counter-productive anger.
