For the reaction H2(g) +O2(g) — H2O (g) how many liters of water can be made from 5 L of oxygen gas at 37.0 Celsius, 1.76atm and an excess of hydrogen?

Answers

Answer:

12.5 L

Explanation:

Part 1 - Finding Number of moles

First thing we need to find out is number of moles of oxygen gas. We can achieve this using the formula: PV=nRT

Pressure (Pa) x Volume (cubic meters) = no. moles x gas constant (8.31 J/K*mol) x Temperature (K)

We can rearrange this formula to solve for no. moles:[tex]n=\frac{PV}{RT}[/tex] and plug in the values to solve.

1 atm = 1.01325 x 10^5 Pa, therefore 1.76atm = [tex]1.76*1.01325*10^{5} =178332Pa[/tex]

1 L = 1 x 10^-3 m^3, therefore 5L = [tex]5*1*10^{-3}=5*10^{-3}m^{3}[/tex]

Finally Kelvin = Celsius + 273.15, therefore 37.0C = [tex]37.0+273.15=310.15K[/tex]

Substituting this all back into the formula we get:

[tex]n=\frac{(178332)(5*10^{-3})}{(8.31)(310.15)}[/tex]

[tex]n=\frac{891.66}{2577.3465}[/tex]

[tex]n=0.346[/tex] moles (3.s.f)

Part 2 - Balancing Equation

The equation given is not balanced so we need to balance it to find the correct molar ratio. We can start by balancing the oxygens as there are less of them. We can see that there are 2 oxygen atoms on the left as denoted by 'O2' but only one on the right in 'H2O', therefore we can add a two in front of the H2O on the right side to balance the oxygen atoms:

[tex]H_{2(g)} +O_{2(g)} - > 2H_{2} O_{(g)}[/tex]

Now we have four hydrogens on the right side so we have a 2 in front of H2 on the left hand side to balance the hydrogens:

[tex]2H_{2(g)} +O_{2(g)} - > 2H_{2} O_{(g)}[/tex]

And voila! The equation is balanced and shows the correct molar ratio.

Part 3 - Calculating moles of water

As we can see from the molar ratio in the balanced equation, every mole of O2 will produce two moles of H2O- the ratio is 1:2. As we have an excess of hydrogen, we only need to worry about the amount of oxygen we have. Therefore to calculate the number of moles of water that can be made we simply need to multiple by the ratio:

[tex]0.346*2=0.692[/tex] moles of water

Part 4 - Converting to Liters

Finally, to convert our amount of moles into volume, we can use water's molecular mass to find the mass and then its density to find its volume. Water's molecular mass is 18.02gmol^-1 (2x1.01+16.00) and its density is 997kg/m^3.

m=nM (mass = no. moles x molecular mass): m=[tex]0.692*18.02=12.46984g[/tex]

rho = m/v (density = mass/volume): [tex]997=12.46984/v[/tex], therefore [tex]v=0.0125m^{3}[/tex]

Finally as mentioned above, 1 L = 1 x 10^-3 m^3, therefore the volume of water that can be made is 12.5 Liters.

I want to know how to solve this question by step by step.
Question: What is the pH value of 500ml of an aqueous solution of 0.005 mol HCl ?

Answers

The pH value of 500 mL of an aqueous solution of 0.005 mole HCl is 2

How do I determine the pH of the solution?

We'll begin our calculations by obtaining the molarity of the solution. Details below:

Volume of solution = 500 mL = 500 / 1000 = 0.50 LMole of HCl = 0.005 moleMolarity = ?

Molarity = mole / volume

Molarity = 0.005 / 0.50

Molarity = 0.01 M

Next, we shall obtain the concentration of the hydrogen ion, H⁺ in the solution. Details below:

HCl(aq) <=> H⁺(aq) + Cl¯(aq)

From the balanced equation above,

1 mole of HCl contains 1 mole of H⁺

Therefore,

0.01 M HCl will also contain 0.01 M H⁺

Thus, the concentration of the hydrogen ion, H⁺ in the solution is 0.01 M

Finally, we shall determine the pH of the solution. Details below:

Concentration of hydrogen ion [H⁺] = 0.01 MpH of solution =?

pH = -Log H⁺

pH = -Log 0.01

pH = 2

Thus, we can conclude that the pH of the solution is 2

What is refraction?

The direction of the light changes as it passes through the air-water barrier. Refraction is the name for this phenomenon. Filling a glass with water and inserting a straw will make it simple to see. It will seem as though the straw is shattered.

Because light travels at a different speed in air and water, refraction takes place. The electromagnetic properties of a specific medium, which differ for air and water, determine the speed at which a light wave propagates in that medium. The speed of light in the air is very near to the vacuum's speed of light, which is 3*108 m/s. The speed of light is slower underwater. Consequently, The direction of the light changes as it passes through the air-water barrier. Refraction is the name for this phenomenon. Filling a glass with water and inserting a straw will make it simple to see. It will seem as though the straw is shattered.

A sample of helium was compressed at 35 °C from a volume of 0.5 L to 0.25 L where the pressure is 500 mmHg. What was the original pressure?

Answers

Answer:

The ideal gas law is a formula that relates the pressure, volume, temperature, and number of moles of a gas. It can be expressed as:

PV = nRT

where P is the pressure of the gas, V is the volume of the gas, n is the number of moles of the gas, R is the gas constant, and T is the temperature in Kelvin.

Since the number of moles and the temperature are constant in this problem, we can rearrange the formula to solve for the pressure:

P = (nRT) / V

Plugging in the known values, we get:

P = (nRT) / V

= (n * R * (35 + 273)) / 0.25 L

= (n * R * 308 K) / 0.25 L

We are given that the pressure is 500 mmHg and the volume is 0.25 L at this pressure, so we can set these equal:

500 mmHg = (n * R * 308 K) / 0.25 L

Solving for n, we get:

n = (500 mmHg * 0.25 L) / (R * 308 K)

We know that the pressure and volume of the gas at its original state are what we are trying to solve for. Let's call the original pressure P_0 and the original volume V_0. We can then express the relationship between the original and final state of the gas as:

P_0 * V_0 = n * R * T

Substituting the expression we found for n and the known values, we get:

P_0 * V_0 = ((500 mmHg * 0.25 L) / (R * 308 K)) * R * 308 K

Solving for P_0, we get:

P_0 = (500 mmHg * 0.25 L) / (R * 308 K) * (R * 308 K) / V_0

= (500 mmHg * 0.25 L) / (V_0)

Since V_0 = 0.5 L, we can substitute this value to get:

P_0 = (500 mmHg * 0.25 L) / (0.5 L)

= 500 mmHg / 2

= 250 mmHg

Therefore, the original pressure of the gas was 250 mmHg.

What is sodium chloride?

Sodium chloride is an ionic compound formed by the combination of sodium metal and chlorine atom. Sodium metal has extra one electron in its valance shell and chlorine needs one more electron into its valence shell. Hence sodium donates its valence electron to chlorine forming NaCl.

NaCl is used as the table salt in food. It is a very important compound in our daily diet. Similarly NaCl is industrially important for many reaction especially in electrochemical processes.

It is given that, the price of 5 kg of NaCl = $179

required mass of NaCl = 65 g = 0.065 Kg

Which balloon, A or B, most accurately illustrates the effusion of a gas from the central balloon?
Calculate the relative rate of effusion for the orange to blue spheres. The root-mean-square speed for the orange spheres is 495.0m/s. The root-meah-5quare speed for the blue spheres is 380.0m/ s.

Answers

According to the claim, Balloon A, which has more blue and less orange, exhibits accurate effusion at a relative effusion rate of 1.303. (orange is 1.303 times more effused than blue).Relative rate of effusion for the orange to blue spheres = 1.531.

What is effusion ?

The process of effusion is when a gas escapes from a container through a hole that is significantly smaller in diameter than the molecules' mean free path.

Gas molecules flow through a small opening in one container and into another by effusion. Graham's law allows rates of effusion to be compared at the same temperature. Diffusion is the random molecular motion-based movement of gas molecules through one or more other types of gas.

Rate of effusion of Orange / Rate of effusion of blue

= [Mblue / Morange]^1/2

Vrms = sqrt [(3RT/M)]

Vorange / Vblue = [ Mblue / Morange]^1/2

Rate of effusion of Orange / Rate of effusion of blue

= 565/ 369

Combustion of 1.125 of an unknown compound containing carbon, hydrogen, and oxygen resulted in 1.649g of CO2 and 0.675g of H2O. If the molar mass is 180g/mol What is the molecular formula?
CxHyOz + O2 → CO2 + H2O

Answers

The molecular formula of the unknown compound, given that it contains carbon, hydrogen, and oxygen is C₆H₁₂O₆

How do I determine the molecular formula?

First, we'll begin by obtaining the mass of carbon, hydrogen and oxygen. Details below:

For Carbon

Mass of CO₂ = 1.649 gMolar mass of CO₂ = 44 g/mol Molar of C = 12 g/mol Mass of C =?

Mass of C = (12 / 44) × 1.649

Mass of C = 0.45 g

For Hydrogen

Mass of H₂O = 0.675 gMolar mass of H₂O = 18 g/mol Molar of H = 2 × 1 = 2 g/mol Mass of H =?

Mass of H = (2 / 18) × 0.675

Mass of H = 0.075 g

For Oxygen

Mass of compound = 1.125 gMass of C = 0.45 gMass of H = 0.075 gMass of O =?

Mass of O = (mass of compound) - (mass of C + mass of H)

Mass of O = 1.125 - (0.45 + 0.075)

Mass of O = 0.6 g

Next, we shall determine the empirical formula. details below:

C = 0.45 gH = 0.075 gO = 0.6 gEmpirical formula =?

Divide by their molar mass

C = 0.45 / 12 = 0.0375

H = 0.075 / 1 = 0.075

O = 0.6 / 16 = 0.0375

Divide by the smallest

C = 0.0375 / 0.0375 = 1

H = 0.075 / 0.0375 = 2

O = 0.0375 / 0.0375 = 1

Thus, the empirical formula of the compound is CH₂O

Finally, we shall determine the molecular formula. Details below:

Molar mass of compound = 180 g/molEmpirical formula = CH₂OMolecular formula =?

Molecular formula = empirical × n = mass number

[CH₂O]n = 180

[12 + (2×1) + 16]n = 180

30n = 180

Divide both sides by 30

n = 180 / 30

n = 6

Molecular formula = [CH₂O]n

Molecular formula = [CH₂O]₆

Molecular formula = C₆H₁₂O₆
