(at 22!c the vapor pressure of water is 19.8 torr.)

Answers

The mass percent of naclo3 in the original sample is 15.1%.

Based on how much oxygen gas is generated when a sample of the compound is heated, the problem asks us to estimate the mass percent of NaClO3 in an impure sample. The quantity of O2 produced and the concentration of NaClO3 in the sample must first be related using a balanced chemical equation.

After making the required calculations, we discover that the original sample's mass percent of NaClO3 is 15.1%. This indicates that of the initial sample's 100 g, 15.1 g are NaClO3, and the remaining impurities. Hence this is the result.

Consider the reaction: CaCO3(s) CaO(s) + CO₂(g) Using standard thermodynamic data at 298K, calculate the entropy change for the surroundings when 1.91 moles of CaCO3(s) react at standard conditions.

Answers

We know that for the given reaction, $\Delta G^{\circ}$ and $\Delta H^{\circ}$ are given as follows:$$\Delta G^{\circ} = -RT ln K = -2.303RTlogK$$$$\Delta H^{\circ} - T\Delta S^{\circ}$$

Where, R is the universal gas constant, T is the temperature and K is the equilibrium constant. Now, we need to find out the entropy change of the surroundings. The surroundings are at a constant temperature of 298 K. The quantity of moles for CaCO3 is 1.91 moles.

We know that $\Delta S^{\circ}_{reaction}$ and $\Delta S^{\circ}_{surroundings}$ are given as follows:

$$\Delta S^{\circ}_{total}

= \Delta S^{\circ}_{reaction} + \Delta S^{\circ}_{surroundings}

= \frac{q_{rev}}{T}$$

The heat of reaction, $q_{rev}$ can be found using $\Delta H^{\circ}$ as follows:$$q_{rev} = -\Delta H^{\circ}$$

This is because at constant temperature, we have $\Delta U = q - w$. The work done in this reaction is $-P_{ext}\Delta V$, but since the reaction is happening at constant pressure, the work done will be 0.

Hence, $q_{rev}$ = $- \Delta H^{\circ}$.Putting in the values in the equation, we get:

$\Delta S^{\circ}_{total} = \Delta S^{\circ}_{reaction} + \Delta S^{\circ}_{surroundings}

= \frac{-\Delta H^{\circ}}{T}$

Now, we need to find $\Delta S^{\circ}_{surroundings}$.

$\Delta S^{\circ}_{surroundings} = -\frac{\Delta H^{\circ}}{T} - \Delta S^{\circ}_{reaction}$

Putting in the values in the equation, we get:

$\Delta S^{\circ}_{surroundings}

= -\frac{\Delta H^{\circ}}{T} - \Delta S^{\circ}_{reaction}

= \frac{-179.8 \ kJ \ mol^{-1}}{(298) \ K} - [-(161.9 - 120.1) \ J \ K^{-1} \ mol^{-1}]$So,$\Delta S^{\circ}_{surroundings}

= -0.813 \ kJ \ K^{-1} \ mol^{-1}$

Hence, the entropy change of the surroundings when 1.91 moles of CaCO3(s) react at standard conditions is -0.813 kJ K^(-1) mol^(-1).

how can the ir spectrum be used to show that there is not starting material left and the products are ketones? saved

Answers

In this case, if the reaction produces ketones, the infrared spectrum should show peaks associated with the C=O and C-H bonds of the ketones, but no peaks associated with the starting material.

The infrared spectrum of a reaction can be used to identify the starting material and products in a reaction. If a reaction is complete, there should be no peaks associated with the starting material, only the products. There are two ways to determine the absence of the starting material, and these are as follows:

Absence of band: In the IR spectrum, if the band that corresponds to the functional group in the starting material is missing, it is evident that the starting material has been entirely consumed in the reaction.Absence of characteristic peaks: Another way to ensure the absence of starting material is to look for characteristic peaks or bands. This method will only be useful if the starting material has a distinct peak or band.

As a result, if that peak or band is absent, it is evident that the starting material has been entirely consumed. To demonstrate that the products are ketones, there are several bands present in the IR spectrum, which can be looked for, and these are as follows:

Characteristic C=O band: A strong band present around 1650-1700 cm-1 is indicative of a carbonyl group. In the case of a ketone, this band is present. Characteristic C-H bending band: Another band present around 1450-1470 cm-1 is indicative of C-H bending. This band is also present in a ketone.Characteristic C-H stretching band: A strong band present around 2800-3000 cm-1 is indicative of C-H stretching. In the case of a ketone, this band is present.

https://brainly.com/question/28738928

#SPJ11

The IR spectrum can be used to identify ketones due to the presence of a strong C=O bond, which results in a characteristic absorption peak around 1730 cm-1. A comparison of the IR spectrum of the starting material and product can be used to confirm that the starting material is completely consumed and the products are ketones.

To demonstrate that there is no beginning material left and that the products are ketones, the IR spectrum can be used. Infrared (IR) spectroscopy is a technique that measures the absorbance of infrared radiation in a substance. When a compound absorbs infrared light, it vibrates at a particular frequency, which is dependent on the chemical structure of the compound. By studying these vibrational frequencies, the IR spectrum of a sample can reveal a great deal about its molecular structure and composition.

IR spectroscopy can be used to show that the starting material has been fully consumed and that the products are ketones. During a reaction that transforms a ketone from a different compound, the IR spectrum of the product will exhibit a carbonyl (C=O) peak at around 1710 cm-1. The absence of peaks corresponding to the beginning material in the product's IR spectrum indicates that the beginning material has been completely consumed. If a new peak that corresponds to the C=O bond appears in the IR spectrum of the product, this shows that the reaction has produced a ketone.

NH.NO, dissolves spontaneously and endothermically in water at room temperature. What can you deduce about the sign and size of As for this solution process relative to the size and sign of AH?

Answers

NH₄NO₃ dissolves endothermically and non-spontaneously in water, with positive ∆H and ∆S.


How does NH.NO dissolve?

Since NH₄NO₃ dissolves spontaneously and endothermically in water at room temperature, it implies that the solution process is non-spontaneous in the opposite direction, and the sign of ∆G for this process is positive. Therefore, the sign of ∆S must be positive, indicating an increase in disorder, and the sign of ∆H must be positive, indicating an endothermic process.

Regarding the relationship between the magnitudes of As and AH, it is not possible to make any definitive conclusions without additional information. The magnitude of As depends on the increase in entropy of the system and the surroundings, while the magnitude of AH depends on the amount of heat absorbed by the system during the process.

A water sample contains 10mgNO3/L. What is the concentration in millimoles/L? Question 2 1 pts 2.2c A water sample contains 10mgNO3
- L. What is the concentration in mg/L as NO 3 −N ?

Answers

The concentration of NO3-N in mg/L = 10 mg/L.

The given water sample contains 10 mg NO3/L.

To find the concentration of NO3 in millimoles/L:

1 mg = 1/1000 g1 mole of NO3 contains 1 + 3x16 = 61 g NO3So, 1 g NO3 = 1/61 mole NO3

Thus, 10 mg NO3 contains (10/1000) * (1/61) mole of NO3= 0.000163934426 mole of NO3

Therefore, the concentration of NO3 in millimoles/L = 0.000163934426 * 1000= 0.163934426 millimoles/L

To find the concentration of NO3-N in mg/L:1 mole of NO3 contains 1 mole of N= 14 g N

Thus, 1 g NO3-N = 1/14 mole of NO3-N

Therefore, 10 mg NO3-N contains (10/1000) * (1/14) mole of NO3-N= 0.000714285714 mol of NO3-N

Therefore, the concentration of NO3-N in mg/L = 0.000714285714 * 14000= 10 mg/L.

1. Calcium phosphate, silicon dioxide, and carbon may be heated together in an
electric furnace to produce phosphorous, as shown in this equation:
2Ca3(PO4)2 + 6SiO₂ +10C
- 6CaSiO3+10CO + P4
a. In this reaction, how many g of silicon dioxide, SiO2, would be needed to make
100 g of phosphorous, P4?
b. How many moles of calcium silicate, CaSiO3, would be formed in a reaction in
which 0.75 moles of carbon, C, is consumed?

Answers

a. To determine the amount of silicon dioxide (SiO₂) needed to produce 100 g of phosphorus (P₄), we need to calculate the stoichiometric ratio between SiO₂ and P₄ in the balanced equation and use it to convert the masses.

From the balanced equation, we can see that the stoichiometric ratio between SiO₂ and P₄ is 6:1. Therefore, for every 6 moles of SiO₂, we obtain 1 mole of P₄.

First, we need to calculate the molar mass of P₄. Phosphorus (P) has a molar mass of 31.0 g/mol, so the molar mass of P₄ is 4 × 31.0 g/mol = 124.0 g/mol.

Next, we can calculate the amount of SiO₂ needed:

Moles of P₄ = Mass of P₄ / Molar mass of P₄ = 100 g / 124.0 g/mol = 0.806 mol of P₄

Since the stoichiometric ratio is 6:1, we need 6 times the moles of SiO₂:

Moles of SiO₂ = 6 × Moles of P₄ = 6 × 0.806 mol = 4.836 mol of SiO₂

Now, we can calculate the mass of SiO₂:

Mass of SiO₂ = Moles of SiO₂ × Molar mass of SiO₂ = 4.836 mol × 60.08 g/mol = 290.9 g

Therefore, approximately 290.9 grams of silicon dioxide (SiO₂) would be needed to produce 100 grams of phosphorus (P₄).

b. To determine the moles of calcium silicate (CaSiO₃) formed when 0.75 moles of carbon (C) is consumed, we need to consider the stoichiometry of the reaction.

From the balanced equation, we can see that the stoichiometric ratio between carbon (C) and calcium silicate (CaSiO₃) is 10:6. Therefore, for every 10 moles of C consumed, we obtain 6 moles of CaSiO₃.

Given that we have 0.75 moles of C, we can calculate the moles of CaSiO₃:

Moles of CaSiO₃ = (6 moles CaSiO₃ / 10 moles C) × 0.75 moles C = 0.45 moles CaSiO₃

Therefore, when 0.75 moles of carbon (C) is consumed, approximately 0.45 moles of calcium silicate (CaSiO₃) would be formed.

Energy is the ability to do work, and to do work means to move something. Every time you or any of your cells move (which is all the time), you are using energy. Humans get all of our energy from eating things. Plants get their energy from the sun. In fact, nearly all the energy on our planet comes from the sun.


Because the sun is a giant fusion reactor, it constantly bombards Earth with energy, which is transferred, stored, and used in many ways. Energy conversion is the transfer of energy from one form to another. For example, chemical energy is stored in the cells of green plants through a process called photosynthesis. This chemical energy started as solar energy, which was converted through a chemical process. The light energy breaks down the chemical bonds in carbon dioxide molecules and converts them to oxygen and carbohydrates (molecules of hydrogen and carbon). When you eat something, the muscles in your body use this stored chemical energy from the sun by splitting the carbohydrate molecules to gain their stored, potential energy.
