Ammonia is produced by the millions of tons annually for use as a fertilizer. It is commonly made from N₂ and H₂ by the Haber process. Because the reaction reaches equilibrium before going completely to product, the stoichiometric amount of ammonia is not obtained. At a particular temperature and pressure, 10.0 g of H₂ reacts with 20.0 g of N₂ to form ammonia. When equilibrium is reached, 15.0 g of NH₃ has formed.
(a) Calculate the percent yield.

Answers

Answer 1

The percent yield was found to be 16.7%.

Steps

the equation is

3H2+N2-->2NH3

the no of moles of H2 is

moles of H2 =(10g H2)x 1mol H2/2.02g H2

=4.95 mol of H2

moles of N2= (20g N2)x 1molN2/28.02g N2

=0.714mol of N2

ratio of H2 andN2 is 3:1

moles of NH3=(0.714molN2)x 2molNH3/ 1molN2

=1.428 mol o NH3

the theoritical mass of NH3= 24.3g

experimental mass = 15g

the percentage yield =experimental mass/ theoritical mass x100%

the percentage yield =16.7%

Answers

Burning natural gas on a stove is an exothermic process.

When natural gas (CH₄) is burned on a stove, it undergoes a chemical reaction with oxygen (O₂) in the air. This combustion reaction releases energy in the form of heat and light, making it an exothermic process.

The combustion of natural gas can be represented by the following balanced chemical equation:

CH₄(g) + 2O₂(g) → CO₂(g) + 2H₂O(g)

In this reaction, methane (CH₄) reacts with oxygen (O₂) to produce carbon dioxide (CO₂) and water (H₂O). The breaking of the carbon-hydrogen and carbon-oxygen bonds in methane and the formation of new carbon-oxygen and hydrogen-oxygen bonds in carbon dioxide and water release energy.

The release of energy in the form of heat is what makes the burning of natural gas on a stove exothermic. This heat energy can be used for cooking or heating purposes.

#SPJ4

The burning of natural gas on a stove is an exothermic reaction.

When natural gas burns on a stove, it undergoes a combustion reaction. Combustion reactions involve the reaction of a fuel (in this case, natural gas) with oxygen to produce carbon dioxide and water vapor. These reactions are typically exothermic, meaning they release heat energy into the surroundings.

In the case of natural gas burning on a stove, the heat energy released is what allows the stove to generate heat and cook food. The combustion of natural gas is a highly exothermic process, which is why it is commonly used as a fuel source for heating and cooking.

It is important to note that the exothermic nature of the reaction can be influenced by other factors such as the presence of a catalyst or the availability of oxygen. However, in the context of a typical stove burner, the burning of natural gas is considered an exothermic reaction.

Which element, when combined with Fluorine, would form an COVALENT compound?

A.Lithium
B.Iron
C.Phosphorus

Answers

Answer:

Explanation:

A covalent compound is a compound formed by covalent bonds. A covalent bond is formed between two atoms where electrons are shared between the two atoms. This forms a molecule.

What determines whether two elements will form a covalent compound or not is the number of valence electrons present in each of the elements.

Fluorine will form a covalent compound with phosphorous because fluorine has 5 electrons in its outermost shell. It needs 3 more to become stable.

Phosphorous also has 5 valence electrons. It needs 3 more to become stable.

What happens is that 3 atoms of FLuorine combine with one atom of Phosphorus, sharing the valence electrons between themselves. This leads to the formation of the PF3 molecule.

Both the Phosphorous and the Fluorine are now stable.

Answer: Phosphorus

you find a piece of cloth painted with organic dye. by analyzing the dye, you find that only 71 % of the carbon-14 originally in the dye remains. when was the cloth painted? express your answer in years to two significant figures.

Answers

The cloth was painted with organic dye approximately 2,300 years ago ( rounded to two significant figures ).

To determine when the cloth was painted with organic dye, we can use the half-life of carbon-14 and the given information that 71% of the carbon-14 remains. The half-life of carbon-14 is 5,730 years.

Step 1: Calculate the decay factor.
Decay factor = remaining percentage / 100
Decay factor = 71% / 100 = 0.71

Step 2: Use the decay formula.
N(t) = N0 * (1/2)^(t / half-life)
0.71 = (1/2)^(t / 5730)

Step 3: Solve for t (time in years).
t / 5730 = log(0.71) / log(1/2)
t = 5730 * (log(0.71) / log(1/2))
t ≈ 2349.27 years

Expressing the answer to two significant figures, the cloth was painted approximately 2,300 years ago.

why is an acid-base extraction being performed rather than a simple solid-liquid or liquid-liquid extraction? what are the acid and the base solutions used for, and why are they both necessary in the procedure?

Answers

Acid-base extraction is performed rather than a simple solid-liquid or liquid-liquid extraction because it allows for the separation of compounds based on their acidity or basicity.

The acid and base solutions are used to react with the compounds in the mixture, causing them to become either more acidic or more basic. This allows for the compounds to be separated into different layers based on their solubility in the acid or base solution.

The acid solution is typically a dilute solution of a strong acid, such as hydrochloric acid or sulfuric acid, and is used to react with basic compounds in the mixture. The base solution is typically a dilute solution of a strong base, such as sodium hydroxide or potassium hydroxide, and is used to react with acidic compounds in the mixture.

Both the acid and base solutions are necessary in the procedure because they allow for the separation of compounds based on their acidity or basicity. Without both solutions, the compounds would not be able to be separated into different layers based on their solubility in the acid or base solution.

1. The reaction

SO2Cl2 (g) → SO2 (g) + Cl2 (g)

is first order in SO2Cl2. Using the following kinetic data, determine the magnitude of the first order rate constant

Answers

The kinetic data is essential to determine the magnitude of the first-order rate constant. To do this, we can use the integrated rate law equation for first-order reactions, which is:

ln [A]t = -kt + ln [A]0

where [A]t is the concentration of reactant at time t, [A]0 is the initial concentration of reactant, k is the rate constant, and t is time.

Using the given reaction and the kinetic data, we can plot ln [SO2Cl2] versus time and determine the slope of the line. The slope of the line will be equal to -k, which will give us the magnitude of the first-order rate constant.

Let's assume that the initial concentration of SO2Cl2 is 0.05 M. Then, the table of data can be used to calculate ln [SO2Cl2] for each time interval. For example, at 10 minutes, [SO2Cl2] = 0.031 M, and ln [SO2Cl2] = -3.471.

Time (min) [SO2Cl2] (M) ln [SO2Cl2]

0 0.05 -2.996
10 0.031 -3.471
20 0.019 -3.957
30 0.012 -4.415
40 0.008 -4.828

Plotting ln [SO2Cl2] versus time gives us a straight line, as expected for a first-order reaction. The slope of the line is -0.177 min^-1, which is equal to the magnitude of the first-order rate constant (k).

Therefore, the magnitude of the first-order rate constant for the given reaction is 0.177 min^-1.
Hi! Based on the given data, we can determine the magnitude of the first order rate constant for the reaction:

SO2Cl2 (g) → SO2 (g) + Cl2 (g)

For a first order reaction, the rate law can be expressed as:

rate = k [SO2Cl2]

Unfortunately, the kinetic data required to calculate the rate constant (k) was not provided in your question. Please provide the necessary data, such as concentration changes and time intervals, so I can help you find the magnitude of the first order rate constant.

The levels of electrolytes in your body can become too low or too high. This can happen when the amount of water in your body changes. The amount of water that you take in should equal the amount you lose. If something upsets this balance, you may have too little water (dehydration) or too much water (overhydration). Some medicines, vomiting, diarrhea, sweating, and liver or kidney problems can all upset your water balance.

How long it would take for drug to degrade to 15% of the initial concentration (0.1M)? k = 0.1hr-1?

Answers

It would take approximately 8.09 hours for the drug to degrade to 15% of the initial concentration.

To calculate the time it would take for the drug to degrade to 15% of the initial concentration (0.1M), we can use the first-order degradation equation:

ln([A]/[A]0) = -kt

where [A] is the concentration of the drug at time t, [A]0 is the initial concentration of the drug, k is the rate constant, and t is the time interval.

We can rearrange this equation to solve for t:

t = -(ln([A]/[A]0)) / k
