2C2H6(9) + 702(9) — 4CO2(g) + 6H20(9)
Enter

Answers

Answer:

21.13 L

Explanation:

Step 1: Write the balanced equation

2 C₂H₆(g) + 7 O₂(g) ⇒ 4 CO₂(g) + 6 H₂O(g)

Step 2: Determine the appropriate volume ratio

Since all the gases are in the same container at the same temperature and pressure, the volume ratio is equal to the molar ratio, because the volume depends on the number of moles. The volume ratio of O₂(g) to H₂O(g) is 7:6.

Step 3: Determine the volume of H₂O produced from 24.65 L of O₂

24.65 L O₂ × 6 L H₂O/7 L O₂ = 21.13 L H₂O

Answers

The question is incomplete. Here is the complete question.

When 2.10 g of a certain molecular compound X are dissolved in 65.0 g of benzene (C₆H₆), the freezing point of the solution is measured to be 3.5°C. Calculate the molar mass of X. If you need any additional information on benzene, use only what you find in the ALEKS Data resource. Also, be sure your answer has a unit symbol, and is rounded to 2 significant digits.

Answer: MM = 47.30 g/mol.

Explanation: There is a relationship between freezing point depression and molality. With this last one, is possible to calculate molar mass or molar weight of a compound.

Freezing Point Depression occurs when a solute is added to a solvent: the freezing point of the solvent decreases when a non-volatile solute is incremented.

Molality or molal concentration is a quantity of solute dissolved in a certain mass, in kg, of solvent. Its symbol is m and it's defined as

[tex]m=\frac{moles(solute)}{kg(solvent)}[/tex]

Freezing point depression and molal are related as the following:

[tex]\Delta T_{f}=K_{f}.m[/tex]

where

[tex]\Delta T_{f}[/tex] is freezing point depression of solution

[tex]K_{f}[/tex] is molal freezing point depression constant

m is molality

Now, to determine molar mass, first, find molality of the mixture:

[tex]\Delta T_{f}=K_{f}.m[/tex]

[tex]m=\frac{\Delta T_{f}}{K_{f}}[/tex]

For benzene, constant is 5.12°C/molal. Then

[tex]m=\frac{3.5}{5.12}[/tex]

m = 0.683 molal

Second, knowing the relationship between molal and moles of solute, determine the last one:

[tex]m=\frac{moles(solute)}{kg(solvent)}[/tex]

[tex]mol(solute)=m.kg(solvent)[/tex]

mol(solute) = 0.683(0.065)

mol(solute) = 0.044 mol

The definition for Molar mass is the mass in grams of 1 mol of substance:

[tex]n(moles)=\frac{m(g)}{MM(g/mol)}[/tex]

[tex]MM=\frac{m}{n}[/tex]

In the mixture, there are 0.044 moles of X, so its molecular mass is

[tex]MM=\frac{2.1}{0.044}[/tex]

MM = 47.30 g/mol

The molecular compound X has molecular mass of 47.30 g/mol.

Calculate the minimum mass of hydrobromic acid that could be left over by the chemical reaction. Be sure your answer has the correct number of significant digits.

Answers

Answer:

Zero

Explanation:

The complete reaction for this is as follows -

HBr + NaOH = NaBr + H2O

1 mole of NaOH reacts with 1 mole of HBr

m(HBr) = 57.4g and M(HBr) = 80.9g/mol

m(NaOH) = 16g and M(NaOH) = 40g/mol

Number of moles = m/M

Substituting the given values we get -

n(HBr) = 57.4 g/80.9 g/mol = 0.709

n(NaOH) = 16 g/40 g/mol = 0.4

n(H2O) = n(NaOH) = 0.40 mol

According to balanced equation

40 gram of NaOH reacts with 81 grams of HBr

41 gram of NaOH will react with 81/40 * 41 = 83.025 gram of HBr

We have only 57.4 g of HBr only hence, 0 HBr will be left.

In a hotel breakfast bar, you see an older woman sticking a fork into a toaster to remove a piece of toast. You warn her not to do that, and she says, "You know, I always wondered why forks conduct electricity so well." As an astute chemistry student, how would you explain it to her? Make sure you provide a relationship to electronegativity, proton pull, and electron distribution in your answer.

Answers

Answer:

See explanation

Explanation:

You see, all these materials we see around us are composed of elements. These elements are unique in their own ways!

Some of them are able to attract tiny negative particles called electrons close to their positive interior called the nucleus. This positive interior is so designated because it contains a positive particle called protons which attract these electrons.

Now, elements are broadly divided into metals and non metals. Protons in metallic elements are less able to pull electrons than protons in non metallic elements. As a result of this, non metals are mostly electronegative because they pull electrons towards themselves while metals are mostly electropositive because they give away their electrons easily. Fork is composed of metallic elements.

Since metals give away electrons easily, they can conduct electricity since electrons are the same charge carriers in electric circuits.

Also, in elements, there is a conduction band and a valence band. Electrons  occupy the valence band but also move into the conduction band. The gap between the valence band and the conduction band in nonmetals is large hence they do not conduct electricity. The gap between the valence band and the conduction band in metals is minimal hence metals conduct electricity.

So if you stick that fork into a toaster, electrons can flow right through the toaster circuit into your body and cause you to be electrocuted.

A solid piece of lead has a mass of 32.00 g and a volume of 2.84 cm^3. From these data, calculate the density of lead in SI units (kilograms per cubic meter).

Answers

Answer:

11267.61 Kg/m³.

Explanation:

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

Mass of lead = 32 g

Volume of lead = 2.84 cm³

Density of lead =.?

Next, we shall convert 32 g to Kg. This can be obtained as follow:

1000 g = 1 Kg

Therefore,

32 g = 32 g × 1 Kg / 1000 g

32 g = 0.032 Kg

Next, we shall convert 2.84 cm³ to m³. This can be obtained as follow:

1 cm³ = 10¯⁶ m³

Therefore,

2.84 cm³ = 2.84 cm³ × 10¯⁶ m³ / 1 cm³

2.84 cm³ = 2.84×10¯⁶ m³

Finally, we shall determine the density of the piece of lead. This can be obtained as follow:

Mass of lead = 0.032 Kg

Volume of lead = 2.84×10¯⁶ m³

Density of lead =.?

Density = mass / volume

Density of lead = 0.032 / 2.84×10¯⁶

Density of lead = 11267.61 Kg/m³

In an experiment, a student places a small piece of pure Mg(s) into a beaker containing 250.mL of 6.44MHCl(aq). A reaction occurs, as represented by the equation above. The student collects the H2(g) produced by the reaction and measures its volume over water at 298 K after carefully equalizing the water levels inside and outside the gas-collection tube. The volume is measured to be 45.6mL. The atmospheric pressure in the lab is measured as 765 torr, and the equilibrium vapor pressure of water at 298 K is 24 torr.
Calculate the following.
(i) The pressure inside the tube due to the H2(g)
(ii) The number of moles of H2(g) produced in the reaction
What is the answer and why?

Answers

Answer:

741 torr

0.81 moles of H2

Explanation:

Given the reaction equation;

Mg(s)+2HCl(aq)  →  MgCl2(aq)+H2(g)

We can obtain the pressure of the gas at 298 K using Dalton's law of partial pressures.

Pressure of gas + vapour pressure of water = 765 torr

vapour pressure of water = 24 torr

765 torr -  vapour pressure of water = Pressure of gas

Pressure of gas = 765 torr - 24 torr = 741 torr

From the question we have;

number of moles of HCl reacted = Concentration * volume

number of moles of HCl reacted = 250/1000 * 6.44 = 1.61 moles

If

2 moles of HCl yields 1 mole of H2

1.61 moles of HCl yields 1.61 * 1/2 = 0.81 moles of H2

An unknown compound is processed using elemental analysis and found to contain 117.4 g of platinum, 28.91 g of carbon, and 33.71 g of nitrogen. How many moles of platinum are present in the compound? Need help ASAP

Answers

Answer:

1 mole of platinum (Pt).

Explanation:

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

Platinum (Pt) = 117.4 g

Carbon (C) = 28.91 g

Nitrogen (N) = 33.71 g

Number of mole of platinum =?

To obtain the number of mole of platinum present in the compound, we shall determine the empirical formula for the compound. The empirical formula for the compound can be obtained as follow:

Pt = 117.4 g

C = 28.91 g

N = 33.71 g

Divide by their molar mass

Pt = 117.4 /195 = 0.602

C = 28.91 /12 = 2.409

N = 33.71 /14 = 2.408

Divide by the smallest

Pt = 0.602 /0.602 = 1

C = 2.409 /0.602 = 4

N = 2.408 / 0.602 = 4

Therefore, the empirical formula for the compound is PtC₄N₄ => Pt(CN)₄

From the empirical formula for the compound (i.e Pt(CN)₄) we can see that the compound contains 1 mole of platinum (Pt).

What is Avogadro's number?

Avogadro’s constant can be explained as the proportionality factor that can be used to count the number of particles such as molecules, atoms, or ions in a given sample with a definite amount of substance.

Avogadro's number can be described as the approximate number of nucleons in 1 gram of substance. The value of the Avogadro constant can be expressed as the mass of one mole of a compound, in grams.

The value of Avogadro’s number is found about 6.022×10²³ mol⁻¹.

Given, the number of molecules of the KOH = 3.21 × 10²⁴

The mass of the one mole of KOH = 56 g/mol

The 6.022 × 10²³ molecules of KOH has mass = 56 g

The mass of 3.21 × 10²⁴ molecules of KOH = 56×(3.21× 10²⁴/6.022 × 10²³)

The question is incomplete. The complete question is :

A 100.0 mL flask is filled with 0.065 moles of A and allowed to react to form B according to the reaction below. The following experimental data are obtained for the amount of A as the reaction proceeds. What is the average rate of appearance of B in units of M/s between t = 10 min. and t = 30 min.? Assume that the volume of the flask is constant. A(g) → B(g)

Time 0.0 10.0 20.0 30.0 40.0

Moles of A 0.065 0.051 0.042 0.036 0.031

Solution :

Consider the following reaction as follows :

[tex]$A \rightarrow B$[/tex]

The experiment data is given as follows :

Time (min) :   0.0        10.0       20.0        30.0       40.0

Moles of A :  0.065    0.051    0.042      0.036     0.031

According to the rate of reaction concept, the rate can be expressed as a consumption of the reactant and formation of the product as follows :

Average rate : [tex]$= -\frac{d[A]}{dt} = \frac{d[B]}{dt} $[/tex]

Now we have to calculate the average rate between 10.0 to 30.0 min w.r.t. A as follows :

Rate  [tex]$=-\frac{(0.051-0.036) mol \times \frac{1}{0.1 \ L}}{(30.0-10.0) mol \times \frac{60 \ s}{1 \ min}}$[/tex]

         [tex]$= 1.25 \times 10^{-4 }\ M/s$[/tex]

Therefore, the rate = [tex]$= 1.3 \times 10^{-4 }\ M/s$[/tex]

A 100.0-mL flask is filled with 0.065 moles of A and allowed to react to form B. Between 10.0 min and 30.0 min, the average rate of appearance of B is 1.3 × 10⁻⁴ M/s.

What is the rate of reaction?

The rate of reaction is the speed at which a chemical reaction takes place, defined as proportional to the increase in the concentration of a product per unit time and to the decrease in the concentration of a reactant per unit time.

Step 1: Write the balanced equation.

A(g) → B(g)

Step 2: Calculate the rate of reaction of A (rate of disappearance of A).

To calculate the rate of disappearance of A (rA) between 10.0 min and 30.0 min, we will use the following expression.

rA = -ΔnA / V. Δt = -(0.036 mol - 0.051 mol)/ (0.1000 L) (30.0 min - 10.0 min)

rA = 7.5 × 10⁻³ M/min

where,

ΔnA is the change in the number of moles of A.Δt is the change in time.

Step 3: Calculate the rate of reaction of B (rate of appearance of B).

The molar ratio of A to B is 1:1.

7.5 × 10⁻³ mol A/L.min × 1 mol B/1 mol A = 7.5 × 10⁻³ mol B/L.min

Step 4: Convert 7.5 × 10⁻³ M/min to M/s

We will use the conversion factor 1 min = 60 s.

7.5 × 10⁻³ M/min × 1 min/60 s = 1.3 × 10⁻⁴ M/s

A 100.0-mL flask is filled with 0.065 moles of A and allowed to react to form B. Between 10.0 min and 30.0 min, the average rate of appearance of B is 1.3 × 10⁻⁴ M/s.

Problem 3 A sample of 2.37 moles of an ideal diatomic gas experiences a temperature increase of 65.2 K at constant volume. (a) Find the increase in internal energy if only translational and rotational motions are possible. (b) Find the increase in internal energy if translational, rotational, and vibrational motions are possible. (c) How much of the energy calculated in (a) and (b) is translational kinetic energy?

Answers

Answer:

a) the increase in internal energy is 3211.78 J

b) dU = 3854.14 J

c) dU[tex]_{T}[/tex] = 1927.06 J

Explanation:

Given the data in question;

Foe a diatomic gas, the degree of freedom are as follow;

lets consider the positional degree of freedom

transitional df = 3

rotational df = 2

vibrational ff = 1

now, the internal energy given by;

U = Nf × 1/2NKT = Nf×1/2×nRT

where Nf is the number of degree of freedom

N is Number of atoms or molecules

n = number of molecules

L is Boltzmann constant

R is universal gas constant

so change in internal energy , change in T is given by

dU =  Nf × 1/2 × nT dT

n = 2.37 moles

dT = 65.2 K

R = 8.314 J/mol.J

a)

Find the increase in internal energy if only translational and rotational motions are possible

since rotational and transitional motion are involved ;

Nf = 3(trasitional) + 2(rotational) = 5

so,

dU = 5 × 1/2  × nRdT

we substitute

dU = 5 × 0.5  × 2.37 × 8.314 × 65.2

dU = 3211.78 J

Therefore, the increase in internal energy is 3211.78 J

b)

Find the increase in internal energy if translational, rotational, and vibrational motions are possible.

Nf = 3 + 2 + 1 = 6

dU = 6 × 1/2  × nRdT

dU = 6 × 0.5  × 2.37 × 8.314× 65.2

dU = 3854.14 J

c)  

How much of the energy calculated in (a) and (b) is translational kinetic energy?

dU[tex]_{T}[/tex] = 3 × 0.5  × 2.37 × 8.314 × 65.2

dU[tex]_{T}[/tex] = 1927.06 J

A public School district furnishes pencils to its elementary school. The pencils the secretary orders from the district warehouse each year are packaged in boxes that contain one gross (12 dozen). The average use of pencils is 9.3 pencils per student. If the school's enrollment is 812 students, what is the minimum number of boxes of pencils that should be ordered?

Answers

Answer:

The minimum number of boxes of pencils to be ordered is 630 boxes.

Explanation:

Since a pupil uses averagely 9.3 pencils

and a box contains 12 pencils,

the school enrollment is also 812

school's enrollment x average use of pencil per student

__________________________________________

            number of pencils in a box

812 x 9.3 = 7551.6

7551.6 /12 = 629.3

Having a total number of 630 boxes of pencils to be ordered.
