1.30 grams of H₂ are reacted with an excess of N₂ to produce 4.21 grams of NH3-
3H₂ + N2 → 2NH3
What was the percent yield for ammonia in this reaction?

A-27.40%
B-28.80%
C-57.50%
D-62.60%

Answers

To find the percent yield, we first need to calculate the theoretical yield, which is the amount of NH3 that would be produced if the reaction went to completion. We can do this by calculating the amount of NH3 that would be produced from the amount of H2 used in the reaction:

From the balanced chemical equation, we see that 3 moles of H2 react with 1 mole of N2 to produce 2 moles of NH3. Therefore, the number of moles of NH3 produced is:

moles of NH3 = (1.30 g H2) / (2.016 g/mol H2) x (2 mol NH3 / 3 mol H2) = 0.427 mol NH3

The molar mass of NH3 is 17.031 g/mol, so the theoretical yield of NH3 is:

theoretical yield = (0.427 mol NH3) x (17.031 g/mol NH3) = 7.28 g NH3

Now we can calculate the percent yield:

percent yield = (actual yield / theoretical yield) x 100%

The actual yield is given as 4.21 g NH3, so:

percent yield = (4.21 g NH3 / 7.28 g NH3) x 100% ≈ 57.85%

Therefore, the percent yield for ammonia in this reaction is approximately 57.85%, which is closest to option C (57.50%).

as dr. jillian swift's research has shown, chemical isotope analysis is particularly useful for considering ancient diets. why is this?

Answers

chemical isotope analysis is particularly useful for considering ancient diets because it provides information that cannot be obtained from other sources.

Chemical isotope analysis is particularly useful for considering ancient diets because it can reveal the types of foods that were consumed by ancient people. This type of analysis is based on the fact that different isotopes of elements such as carbon, nitrogen, and oxygen are found in different types of foods.

For example, the isotopes of carbon found in wheat and barley are different from those found in meat and dairy products. By analyzing the isotopes of carbon, nitrogen, and oxygen in the bones and teeth of ancient people, researchers can determine what types of foods were consumed by these people.

This information can help researchers to understand how ancient people lived, what types of foods they ate, and how their diets may have affected their health and well-being. It can also provide insight into how food production and consumption patterns have changed over time.

A solution of 0.15M NH3 is only 1.1% ionized in solution. Calculate the pKa of NH4+. The Kb for NH3 is 1.8 x 10-5.m

Answers

The pKa of [tex]NH^{4+[/tex] would be 9.51.

pKa calculation

To solve the problem, we can use the equation for the ionization constant of a weak base, Kb:

Kb = [NH4+][OH-] / [NH3]

Since NH3 is a weak base, we can assume that the concentration of OH- ions produced by water is negligible. Thus, we can simplify the equation to:

Kb = [NH4+] / [NH3]

The equilibrium expression for the ionization of NH3 can be written as:

NH3 + H2O ⇌ NH4+ + OH-

The equilibrium constant for this reaction is:

Kw = [NH4+][OH-] / [NH3] = 1.0 x 10^-14

Since the concentration of OH- is negligible, we can assume that:

Kw = [NH4+][OH-] / [NH3] ≈ [NH4+][OH-] / [NH4+] = [OH-]

Substituting Kb and Kw into the equation above, we get:

Kb x [OH-] = Kw[OH-] = Kw / Kb = 1.0 x 10^-14 / 1.8 x 10^-5 = 5.6 x 10^-10

Since NH3 is only 1.1% ionized, we can assume that [NH4+] ≈ [OH-] = 5.6 x 10^-10

Using the equation for the ionization constant of NH4+, we get:

Ka = [NH3][H3O+] / [NH4+]

Since NH3 is a weak base, we can assume that [H3O+] ≈ [OH-] = 5.6 x 10^-10

Substituting the values into the equation, we get:

Ka = (0.15 x 0.011)/(5.6 x 10^-10) = 3.1 x 10^-10

Finally, we can use the relationship between Ka and pKa:

pKa = -log(Ka) = -log(3.1 x 10^-10) = 9.51

Therefore, the pKa of NH4+ is 9.51.

Why do clouds form behind a cold front and ahead of a warm front?

Answers

Clouds form behind a cold front and ahead of a warm front because of the difference in temperature and moisture between the two air masses.


When a cold front, which is an area of colder air, meets a warm front, which is an area of warmer air, the colder air forces the warmer air to rise. As the warmer air rises, it cools and the moisture in the air condenses to form clouds. This process is called adiabatic cooling.

Similarly, when a warm front meets a cold front, the warmer air rises over the colder air and cools, forming clouds. However, because the warm air is less dense than the cold air, it rises more slowly and the clouds that form are typically less dense and less likely to produce precipitation.

In both cases, the difference in temperature and moisture between the two air masses leads to the formation of clouds. This is why we often see clouds forming behind a cold front and ahead of a warm front.

Answers

After 11 years, a tritium sample will contain about 41.6% of the original amount.

How many years are there in a tritium half-life?

A hydrogen isotope with a half-life of 12.3 years, tritium (also known as T or 3H) decays to 3He through beta decay.

Applying the formula for the half-life:N(t) = N₀(1/2)^(t/T)

where N(t) is the quantity still present at time t, N0 is the starting quantity, t is the time since the beginning of time, and T is the half-life.

For tritium, we have T = 12.3 years, and t = 11 years.

Substituting these values, we get:

N(11) = N₀(1/2)^(11/12.3)

We can multiply by 100 and divide N(11) by N0 to determine how much is left:

% remaining = (N(11) / N₀) * 100

How many grams of AgNO3 are needed to prepare 237.3 mL of 0.0312 M AgNO3 solution? m(AgNO3) = ___g​

Answers

Answer:

we need 1.605 grams of AgNO3 to prepare 237.3 mL of 0.0312 M solution.

Explanation:

First, let's write down the formula for calculating the mass of a solute:

mass = molarity x volume x molar mass

We are given the volume and molarity of the solution, so we just need to find the molar mass of AgNO3.

AgNO3 has a molar mass of 169.87 g/mol.

Now we can substitute into the formula:

mass = 0.0312 mol/L x 0.2373 L x 169.87 g/mol

mass = 1.605 g

Therefore, we need 1.605 grams of AgNO3 to prepare 237.3 mL of 0.0312 M solution.

What is the procedure for making nitrous acid?

Nitrous acid is frequently created by adding a mineral acid to aqueous sodium nitrite solutions. Typically, acidification is carried out at ice-cold temperatures, and HNO2 is consumed on-site. Nitrous acid in its free form is unstable and breaks down quickly.

In a neutralization process, weak nitrous acid (HNO2) reacts with strong basic KOH.

HNO2 + KOH → KNO2 + H2O

Then, we determine how many moles of KOH were used:

volume KOH x concentration equals moles KOH. KOH

moles KOH = 0.190 L x 0.377 mol/L

moles KOH = 0.07153 mol

Next, we calculate the initial concentration of HNO2:

concentration HNO2 = moles HNO2 / volume HNO2

concentration HNO2 = 0.07153 mol / 0.190 L

concentration HNO2 = 0.3765 M

[HNO2] = 0.5 x 0.3765 M

[HNO2] = 0.1883 M

The following equation can be used to model how nitrous acid dissociates in water:

HNO2 + H2O ⇌ H3O+ + NO2-

The following equation relates the pKa to the acid dissociation constant, Ka, for this reaction:

pKa = -log Ka

So we can find the Ka value from the given pKa:

pKa = -log Ka

3.35 = -log Ka

Ka = 10⁻³

Ka = 4.47 x 10⁻⁴

The relationship shown below is true for the concentrations of the species involved at equilibrium:

Ka = [H3O+][NO2-] / [HNO2]

Ka = [H3O+][NO2-] / [HNO2]

Ka = [H3O+] [HNO2]

Solving for [H3O+], we get:

[H3O+] = Ka / [HNO2]

[H3O+] = (4.47 x 10⁻⁴) / (0.1883 M)

[H3O+] = 0.002374 M

Finally, we can calculate the pH of the solution:

pH = -log[H3O+]

pH = -log(0.002374)

pH = 2.624

Answers

The percent composition by mass of sodium chloride and potassium chloride in the mixture is 90.4% sodium chloride and 9.6% potassium chloride.

The percent composition by mass of sodium chloride and potassium chloride in the mixture can be calculated using the following equation:

%Mass Sodium Chloride = (Mass of Sodium Chloride / (Mass of Sodium Chloride + Mass of Potassium Chloride)) x 100

%Mass Potassium Chloride = (Mass of Potassium Chloride / (Mass of Sodium Chloride + Mass of Potassium Chloride)) x 100

Mass of Sodium Chloride = (32.8mL)(0.384M)(58.44g/mol) / 1000mL = 0.73 g

Mass of Potassium Chloride = 0.807 g - 0.73 g = 0.077 g

%Mass Sodium Chloride = (0.73 g / (0.73 g + 0.077 g)) x 100 = 90.4%

%Mass Potassium Chloride = (0.077 g / (0.73 g + 0.077 g)) x 100 = 9.6%

Compare the ways in which igneous and metamorphic rocks form. Include examples in your answer. (6 marks QWC)

Answers

Answer:

Igneous and metamorphic rocks are two of the three major types of rocks found on Earth, with the third being sedimentary rocks. Igneous rocks are formed from the solidification of molten magma or lava, while metamorphic rocks are formed from the transformation of existing rocks due to high temperature and pressure.

The formation of igneous rocks begins when magma or lava cools and solidifies. Magma is molten rock that is located beneath the Earth's surface, while lava is magma that has erupted onto the surface. When magma or lava cools and solidifies, it forms igneous rocks. There are two types of igneous rocks: intrusive and extrusive. Intrusive igneous rocks form when magma cools and solidifies slowly beneath the Earth's surface, while extrusive igneous rocks form when lava cools and solidifies quickly on the Earth's surface. Examples of igneous rocks include granite, basalt, and pumice.

In contrast, the formation of metamorphic rocks occurs when existing rocks are transformed due to high temperature and pressure. Metamorphism can occur when rocks are buried deep within the Earth's crust, or when they are subjected to high pressure and temperature due to tectonic activity. The transformation of existing rocks can result in the formation of new minerals, textures, and structures within the rocks. Examples of metamorphic rocks include marble, slate, and gneiss.

In conclusion, the formation of igneous and metamorphic rocks differ in terms of their origin and formation process. Igneous rocks are formed from the solidification of molten magma or lava, while metamorphic rocks are formed from the transformation of existing rocks due to high temperature and pressure. While both types of rocks can be found in various locations around the world, they differ in their properties, appearance, and composition.

Answer:

524.21 g/mol

Explanation:

The molar mass of a compound is the sum of the atomic masses of all the atoms in its chemical formula. The molecular formula of Prussian Blue is Fe(CN)18.

The atomic mass of iron (Fe) is 55.85 g/mol. The atomic mass of carbon is 12.01 g/mol and the atomic mass of nitrogen (N) is 14.01 g/mol. So the molar mass of the CN group is 12.01 g/mol + 14.01 g/mol = 26.02 g/mol.

Since there are 18 CN groups in one molecule of Prussian Blue, the total contribution of the CN groups to the molar mass of Prussian Blue is 18 × 26.02 g/mol = 468.36 g/mol.

So the molar mass of Prussian Blue is 55.85 g/mol + 468.36 g/mol = 524.21 g/mol.

How does blood flow through your body. What is the path that it takes

Answers

A closed network of blood vessels, comprising arteries, veins, and capillaries, transports blood throughout the body.

These are some examples of the route blood takes:

The largest artery in the body, the aorta, is used to push blood out of the heart.

The aorta divides into smaller arteries that supply blood to the body's many organs and tissues.

The arteries gradually shrink to the size of arterioles, which are tiny channels that can assist control blood pressure and flow.

The tiniest blood veins in the body, known as capillaries, are then reached via arterioles. The blood and cells of the organism exchange nutrients and gases through capillaries.

Then, blood exits the capillaries and enters the tiny veins called venules.
