Answer:

the pH of the pond is 4.0963

Explanation:

 Given the data in the question;

4FeS₂(s) + 11O₂(g)  ------>  2Fe₂O₃(s) + 8SO₂(g)

and oxidation of sulfur dioxide to trioxide

SO₃(g) + H₂O(l)  --------> H₂SO₄(aq)

given that; coal = 61.7 metric tons = 61700 kg

1.20 % by weight S, therefore mass of sulfur in coal will be;

⇒ 61700 × 1.20% = 740.4 kg

moles of sulfur = (740.4 × 1000 g) / 32 g/mole = 23,137.5 moles

moles of so₂ produced

= same moles of so₃ and same moles of H₂SO₄ = 23,137.5 moles

volume of pond = 397 m x 258 m x 5.64 m = 577,682.64 m³ = 577682640 L

Molarity = moles / volume = 23,137.5 / 577682640 = 4.0052 × 10⁻⁵ M

now each mole of  H₂SO₄ will give 2 moles of H⁺

[H⁺] = 2 × 4.0052 × 10⁻⁵ =  8.0104 × 10⁻⁵ M

pH = -log[H⁺]  

pH = -log [ 8.0104 × 10⁻⁵ M ]

pH = 4.0963

Therefore, the pH of the pond is 4.0963

Answer:

Container 2 has the lowest average molecular speed

Container 4 has the highest average molecular speed

Explanation:

Step 1: Data given

Atomic mass of Xe = 131.29 g/mol

Container 1: Number of moles Xe = 0.115 moles; volume = 4.87 L; temperature= 446K

Container 2: Number of moles Xe = 0.599 moles; Volume = 5.78 L; temperature= 306K

Container 3: Number of moles Xe = 0.444 moles; Volume = 2.39L; Temperature = 408K

Container 4: Number of moles Xe = 0.556 moles; Volume=2.11L; Temperature =446K

Step 2: Calculate average molecular speed

Average molecular speed V = √(8RT/πM)

→With R = he gas constant expressed in units of J/mol-K

→with T = the temperature in Kelvin

→with M = the molar mass of the gas

Average molecular speed depends on T and M

Since it's all Xenon, M is the samefor the 4 containers

Container 1:

V1 = √(8*8.314*446K/π*131.29)

V1 = 8.48

has an average molecular speed between the highest and the lowest

V2= √(8*8.314*306K/π*131.29)

V2= 7.03

has the lowest average molecular speed

V3 = √(8*8.314*408K/π*131.29)

V3 = 8.11

has an average molecular speed between the highest and the lowest

V4 = √(8*8.314*446K/π*131.29)

V4 = 8.48

Since the volume is smaller than in container 1 the average molecular speed will be a higher

has the highest average molecular speed

Explanation:

The concentration of the solution is given as the ratio of the moles and the volume of the solution. The concentration of hydrogen fluoride is 50 M.

Molarity is the colligative property that is expressed in the terms of the moles of the solute expressed per liter of solution. It is given by the formula:

[tex]\rm Molarity = \rm \dfrac{\text{moles of solute}}{ \text{liters of solution}}[/tex]

Given,

Volume of solution (V) = 0.5 L

Moles of the solute (n) = 25 moles

Molar concentration (M) = ?

Substituting values in the equation we get:

[tex]\begin{aligned} \rm M &= \rm \dfrac{n}{V}\\\\&= \dfrac{25}{0.5}\\\\&= 50\end{aligned}[/tex]

Therefore, 50 M is the concentration of 25 mol Hydrogen fluoride.

Answer: To be separated using GC, analytes must be volatile.

An air peak is commonly used to determine the dead time when using a TCD detector.

An FID is insensitive to non-combustible gases such as water and carbon dioxide.

A column temperature equal to or slightly above the average boiling point of the sample components results in a reasonable elution time.

Explanation:

The gas chromatography works on the principle of separation of gaseous substances based on the differences of vapor pressure. The thermal conductivity detector works on the principle of detection of effluents from the has chamber and the air peak gives indication of the retention time of the effluents. Flame ionization detector can be used for the detection of organic compounds but insensitive for the detection of halogens, non-combustible substances like carbon dioxide and water. The temperature of the column is kept higher than the average boiling point of the substance so as to attain separation of substances by the differences in the elution time.

Explanation:

Explanation:

X = Group 1 metal

Y = Group 7 Non metal

The dots basically signifies the group.

Metal loses electrons and non metal gains electron. The valency of X is 1 and that of Y is 7.

X atom loses one electron and Y atom gains one electron.

The bond that forms between a metal and a non metal is an ionic bond.

The electrons, in redox reaction get partially transferred by one to another element.

A redox reaction occurs when the oxidation states of the substrate change. The loss of electrons or maybe an increase in the oxidation state of a chemical and its atoms is referred to as oxidation. The gain of electrons or a reduction in the oxidation state of either a chemical or its atoms is referred to as reduction. The oxidation as well as reduction process can be seen in same reaction which is introduced as redox reaction.

Electron can be considered as sub atomic particle which carry negative charge on it.

The given reactions are:

a. Ca(s) + Cl2(g) → CaCl2(s)

b. 4Cu(s) + O2(g) → 2Cu2O(s)

After transferring two electron in both reaction Ca and Cu it will form  CaCl2 and 2Cu2O.

Therefore, after transferring partially electrons one elements get converted into another kind of molecule

Answer:

uhhh not really i don't even know what that is LOL

Answer:

molar mass of  unknown monoprotic acid = 114.1 g / mole.

Explanation:

Note: This question is incomplete and lacks necessary data to solve for the required calculation. However, I have similar question on the internet and seen the question completely and will be using that data to solve for this question in order to solve required calculation. Besides that, complete question asks us to solve for molar mass of the acid used.

Note: I have attached the screenshot of the complete question, please have a look on it in the attachment below.

Calculation:

Volume = 34.81mL

34.81 mL of 0.4346 M potassium hydroxide

= 0.03481 L * 0.4346 mole / L

= 0.01513 mole.

Balance equation:

HA + KOH ----> KA + H2O

As we know from the question,

one mole HA neutralize with 1 mole KOH.

mole of unknown monoprotic acid = 0.01513 mole.

And we know that the formula for mole is:  

mole = mass / molar mass

Making molar mass as the subject:

 Molar mass = mass / mole

Molar mass = 1.726 g / 0.01513 mole

Molar mass = 114.1 g / mole.

So,  

Molar mass of  unknown monoprotic acid = 114.1 g / mole.

Answer:

32.7 L of H₂

Explanation:

We'll begin by calculating the number of mole in 95 g of Zn. This can be obtained as follow:

Mass of Zn = 95 g

Molar mass of Zn = 65 g/mol

Mole of Zn =?

Mole = mass /Molar mass

Mole of Zn = 95/65

Mole of Zn = 1.46 mole

Next, we shall determine the number of mole of H₂ produced by the reaction of 95 g (i.e 1.46 mole) of Zn. This can be obtained as illustrated below:

Zn + H₂SO₄ —> ZnSO₄ + H₂

From the balanced equation above,

1 mole of Zn reacted to produce 1 mole of H₂.

Therefore, 1.46 mole of Zn will also react to produce 1.46 mole of H₂.

Finally, we shall determine the volume of H₂ obtained at STP. This can be obtained as follow:

1 mole of H₂ = 22.4 L at STP.

Therefore,

1.46 mole of H₂ = 1.46 × 22.4

1.46 mole of H₂ = 32.7 L at STP

Thus, 32.7 L of H₂ were obtained from the reaction.

Answer:

Explanation:

Mass = 66.6 gram

Density = 0.790 g/mL

Volume = Mass ÷ Density

Volume = 66.6 ÷ 0.790

Volume = 84.30 mL

Answer:

0.998 atm.

Explanation:

NOTE: The temperature is missing in the above question and the value is 20 °C

From the question given above, the following data were obtained:

Volume (V) = 10.0 L

Number of mole of H₂ = 0.2 mole

Number of mole N₂ = 0.215 mole

Temperature (T) = 20 °C

Total pressure (P) =?

Next, we shall determine the total number of mole in flask. This can be obtained as follow:

Number of mole of H₂ = 0.2 mole

Number of mole of N₂ = 0.215 mole

Total number of mole (n) =?

n = mole of H₂ + mole of N₂

n = 0.2 + 0.215

n = 0.415 mole

Thus, the total number of mole in the flask is 0.415 mole

Next, we shall convert 20 °C to Kelvin temperature. This can be obtained as follow:

T(K) = T(°C) + 273

Temperature (T) = 20 °C + 273

Temperature (T) = 293 K

Finally, we shall determine the total pressure in the flask. This can be obtained as follow:

Volume (V) = 10.0 L

Total number of mole (n) = 0.415 mole

Temperature (T) = 293 K

Gas constant (R) = 0.0821 atm.L/Kmol

Total pressure (P) =?

PV = nRT

P × 10 = 0.415 × 0.0821 × 293

Divide both side by 10

P = (0.415 × 0.0821 × 293) / 10

P = 0.998 atm.

Therefore, the total pressure in the flask is 0.998 atm.

Answer:

See explanation

Explanation:

We can convert cyclohexanol to cyclohexene in the presence of a strong acid such as sulfuric acid catalyst in a test tube at 60 oC by heating up the mixture to about 80 oC. This is a dehydration reaction so water is removed  to yield the alkene. A drying agent is used to remove any trace amount of water left in the system. This overall reaction is endothermic.

Also, the reverse is the case when we want to carry out the hydration of cyclohexene to yield cyclohexanol. The overall reaction is exothermic and involves the addition of more water to the alkene and then cooling down the system to about 40 oC.

Answer:

To calculate the concentration of the acid solution, use three steps.

1. Use the volume of base used at the endpoint and the known concentration of the base solution to find the moles of base used.

2. Use the stoichiometry to find the moles of acid from the moles of base.

3. Divide the moles of acid by the volume of acid used in the titration to find the concentration of acid.

Explanation:

Titration is the process used in volumetric analysis to determine the amount of a substance present in a given sample.

In any titration, a solution of known concentration known as the standard solution is used to react with a solution of of unknown concentration. The reacting volumes of the solutions are then used to calculate the unknown  concentration of the second solution.

In acid-base neutralization reactions, an equivalence point/endpoint of the neutralization titration is obtained and is the point at which the moles of H+ is equal to the moles of OH- . An indicator is used to indicate the equivalence point during a titration by a color change observed in the indicator.

In order to calculate the concentration of an acid, we need to know accurately, use three steps:

1. Use the volume of base used at the endpoint and the known concentration of the base solution to find the moles of base used.

2. Use the stoichiometry of the reaction to find the moles of acid from the moles of base.

3. Divide the moles of acid by the volume of acid used in the titration to find the concentration of acid.
