A given mass of oxygen is 0.15dm³ at 60°c and 1.01 × 105 nm-² .find its pressure at the same temperature if it's volume is charged to 0.39 dm³​

Answers

Answer 1

The pressure of the oxygen at 60°C and a volume of 0.39 dm³ is 3.5 × 104 nm-².

To solve this problem, we can use the combined gas law, which relates the pressure, volume, and temperature of a gas:

(P1 x V1) / T1 = (P2 x V2) / T2

where P1, V1, and T1 are the initial pressure, volume, and temperature of the gas, and P2, V2, and T2 are the final/absolute pressure, volume, and temperature.

We are given the following:

Initial pressure P1 = 1.01 × 105 nm-² (nanometers squared)

Initial volume V1 = 0.15 dm³

Initial temperature T1 = 60°C = 333 K

Final volume V2 = 0.39 dm³

Final temperature T2 = 60°C = 333 K

We need to find the final pressure P2.

Plugging these values into the combined gas law, we get:

(P1 x V1) / T1 = (P2 x V2) / T2

(1.01 × 105 nm-² x 0.15 dm³) / 333 K = (P2 x 0.39 dm³) / 333 K

Simplifying this equation, we get the following:

P2 = (1.01 × 105 nm-² x 0.15 dm³ x 333 K) / (0.39 dm³ x 333 K)

P2 = 3.5 × 104 nm-²

Therefore, the pressure of the oxygen at 60°C and a volume of 0.39 dm³ is 3.5 × 104 nm-².

the volume of a certain gas was found to be 1600cm3 when the pressure was 800mmHg. At what pressure the volume will be decreased to 80% of the original volume.​

Answers

The pressure will be 1000 mmHg when the volume is decreased to 80% of the original volume.

What is Boyle's law ?

Boyle's law, which states that at a constant temperature, the pressure and volume of a gas are inversely proportional.

We can use Boyle's law. This means that:

P 1V1 = P2V2

Where

P1 and V1 are the initial pressure and volume P2 and V2 are the final pressure and volume

In this case, we know that the initial pressure (P1) is 800 mmHg and the initial volume (V1) is 1600 cm3. We want to find the final pressure (P2) when the volume (V2) is decreased to 80% of the initial volume:

V2 = 0.8V1 = 0.8 x 1600 cm3 = 1280 cm3

Substituting these values into Boyle's law, we get:

P1V1 = P2V2

800 mmHg x 1600 cm3 = P2 x 1280 cm3

Solving for P2, we get:

P2 = (800 mmHg x 1600 cm3) / 1280 cm3

P2 = 1000 mmHg

Therefore, the pressure will be 1000 mmHg when the volume is decreased to 80% of the original volume.

The half-life for Carbon-14 is 5614 years. An ancient piece of cloth is found to contain ¼ of its original Carbon-14. How old is the cloth? Describe or show in detail how you solved this.

Answers

Answer:

To determine the age of the ancient cloth, we can use the concept of radioactive decay and the half-life of Carbon-14.

Carbon-14 is a radioactive isotope of carbon, which decays over time into nitrogen-14 through beta decay. The half-life of Carbon-14 is 5614 years, which means that after 5614 years, half of the original amount of Carbon-14 in a sample will have decayed.

In this case, the cloth contains only ¼ of its original Carbon-14. This means that three half-lives have passed since the cloth was first created, as each half-life reduces the amount of Carbon-14 by half.

To determine the age of the cloth, we can use the following formula:

N = N0(1/2)^t/T

where N is the current amount of Carbon-14 in the cloth, N0 is the original amount of Carbon-14 in the cloth, t is the time that has passed, and T is the half-life of Carbon-14.

We know that N = ¼ N0, and T = 5614 years. Plugging these values into the formula, we get:

¼ N0 = N0(1/2)^(3/T)

Solving for t, we get:

t = (3/T) * log(2)

Substituting in T = 5614 years, we get:

t = (3/5614) * log(2) ≈ 1,684 years

Therefore, the cloth is approximately 1,684 years old.

In summary, we can use the concept of radioactive decay and the half-life of Carbon-14 to determine the age of the ancient cloth. By knowing the current amount of Carbon-14 in the cloth, we can calculate the time that has passed since it was first created using a simple formula. In this case, the cloth is approximately 1,684 years old.

Calculate the amount of heat needed to convert 230.0g of ice at -10C to water at 0C

Answers

Answer:

It would take approximately 81.65 kJ (or 81,650 J) of heat to convert 230.0g of ice at -10C to water at 0C.

Explanation:

To calculate the amount of heat needed to convert ice at -10°C to water at 0°C, we need to consider two steps:

1. Heating the ice from -10°C to 0°C (heat required to raise the temperature of ice)

2. Melting the ice into water at 0°C (heat required to change the state of ice)

Let's first calculate the heat required for step 1:

Q1 = m × c × ΔT

where Q1 is the heat required, m is the mass of the ice, c is the specific heat capacity of ice, and ΔT is the change in temperature.

The specific heat capacity of ice is 2.09 J/g°C, and ΔT is (0°C - (-10°C)) = 10°C.

So, Q1 = 230.0 g × 2.09 J/g°C × 10°C = 4827 J

Now, let's calculate the heat required for step 2:

Q2 = m × Lf

where Q2 is the heat required, m is the mass of the ice, and Lf is the latent heat of fusion of ice.

The latent heat of fusion of ice is 334 J/g.

So, Q2 = 230.0 g × 334 J/g = 76820 J

Therefore, the total amount of heat needed to convert 230.0g of ice at -10C to water at 0C is:

Qtotal = Q1 + Q2 = 4827 J + 76820 J = 81647 J

Therefore, it would take approximately 81.65 kJ (or 81,650 J) of heat to convert 230.0g of ice at -10C to water at 0C.

Answers

Where energy from the sun is enough to break the bonds between water molecules in the ice and convert them directly into water vapor without passing through the liquid phase.

What is Sublimation?

Sublimation is a physical process in which a solid substance is transformed directly into a gas without passing through the liquid phase. In other words, sublimation occurs when a solid substance changes its state directly to a vapor state, bypassing the liquid state.

Sublimation occurs when the vapor pressure of a solid exceeds the atmospheric pressure, causing the solid to transform into a gas without melting. This process requires energy to break the intermolecular bonds holding the solid together. This energy is typically supplied through heating or a decrease in pressure.

Water in Earth's polar regions can produce water vapor even when the temperature is very low due to a process called sublimation. Sublimation is a phase transition from a solid directly to a gas, without passing through the liquid phase. This process occurs when the vapor pressure of the solid (in this case, ice) exceeds the atmospheric pressure.

In the polar regions, the air is very cold and dry, with low atmospheric pressure. When the sun shines on the ice or snow, it provides energy that causes the surface layer of the ice to evaporate directly into water vapor without melting into liquid water.

mass fraction of water in a solution is 0.8. what is the volume of water containing 150g of sucrose​

Answers

Answer:

The volume of water containing 150g of sucrose is 600 mL.

Step by step explanation:

To solve this problem, we need to first determine the total mass of the solution. We know that the mass fraction of water is 0.8, which means that water makes up 80% of the solution.

Therefore, the mass fraction of the other component (sucrose) is 0.2, or 20%.

Let's assume we have a total mass of 1 kg (1000 grams) of solution, then the mass of water in the solution would be:

Mass of water = 0.8 x 1000 grams = 800 gramsSince the mass of sucrose is 20% of the total mass,

we can calculate it as:

Mass of sucrose = 0.2 x 1000 grams = 200 grams

Now we can use the density of water to calculate the volume of water that contains 800 grams.

The density of water is approximately 1 gram per milliliter (g/mL).

Therefore, the volume of water that contains 800 grams is:

Volume of water = 800 grams / 1 g/mL = 800 mL

Finally, we can calculate the volume of water that contains 150 grams of sucrose by using the mass ratio of sucrose to water, which is:

150 grams of sucrose / 200 grams of sucrose = 0.75

This means that the volume of water containing 150 grams of sucrose is 0.75 times the volume of water in the entire solution:

Volume of water containing 150g of sucrose = 0.75 x 800 mL = 600 mL

Therefore, the volume of water containing 150g of sucrose is 600 mL.

Answers

At the same temperature, the pH of a 0.001 M Ca(OH)2 aqueous solution will be higher than that of a 0.001 M NaOH(aq).

The pH value of a solution is determined by the concentration of hydrogen ions in the solution. Higher hydrogen ion concentration in a solution leads to lower pH values, while lower hydrogen ion concentration results in higher pH values. The chemical formulas of the two solutions are: Ca(OH)2(aq) → Ca2+(aq) + 2OH-(aq) NaOH(aq) → Na+(aq) + OH-(aq). The hydroxide ion (OH-) concentration of a Ca(OH)2 solution is twice that of a NaOH solution of equal concentration. This is due to the fact that 1 mole of Ca(OH)2 produces two moles of OH- ions, whereas 1 mole of NaOH produces only 1 mole of OH- ions. As a result, the pH of Ca(OH)2 is higher than that of NaOH.

Answers

When Hydrogen gas was cooled from 15 C to -15 C by use of the formula we get the value of the original volume as 671.875 mL.

Charles' Law describes the link that exists between the volume and temperature of a specific amount of ideal gas kept at constant pressure.

This rule says that for a given amount of gas at constant pressure, as the temperature rises, the volume of the gas rises, and as the temperature falls, the volume of the gas falls because temperature is directly proportional to the energy of movement of the gas molecules. That is, the volume of the gas is precisely proportional to its temperature.

The kinetic energy of a gas's molecules is exactly proportional to its absolute temperature, according to the kinetic theory of gases. The kinetic energy of the component molecules reduces as the temperature of the gas falls.

We have,

v1 t1 = v2 t2

v1 = x

v2 = 750 mL

t1 = 15 + 273 = 288 K

t2 = -15 + 273 = 258 K

putting the values in the equation,

x(288) = (750)(258)

x = 193500 / 288

The balanced chemical equation for the reaction between nitrogen and hydrogen to form ammonia is:

N2 + 3H2 → 2NH3

We can use the ideal gas law to calculate the number of moles of nitrogen:

PV = nRT

where P is the pressure, V is the volume, n is the number of moles, R is the gas constant (0.0821 L atm mol K), and T is the temperature in Kelvin.

The number of moles of NaCl can be calculated using its molar mass and the given mass of NaCl:

Number of moles = mass / molar mass

The molar mass of NaCl is 58.44 g/mol (22.99 g/mol for Na + 35.45 g/mol for Cl).

Number of moles of NaCl = 65 g / 58.44 g/mol = 1.1138 mol (rounded to 4 decimal places)

The volume of the solution is given as 1 liter.

Now we can use the formula for molarity:

Molarity (M) = number of moles / volume (in liters)

M = 1.1138 mol / 1 L = 1.1138 M (rounded to 2 decimal places)

Answers

A- the ratio of mol water to mol dry gas is 10/100, B- The required air feed rate is 166.67 kmol/h, C- composition of exhaust gas steam is 100% of water.

a) On a wet basis, the molar composition of the gas is 70.0 mol % methane, 15.0 mol % ethane, 5.0 mol % ethylene, and 10.0 mol % water. On a dry basis, the molar composition is 78.26 mol % methane, 17.74 mol % ethane, 4.26 mol % ethylene, and 0 mol % water. The ratio of mol water to mol dry gas is 10.0/100.


b) If 100 kg/h of the fuel is to be burned with 30% excess air, the required air feed rate is 133.33 kmol/h. If the combustion is only 75% complete, the air feed rate would be 166.67 kmol/h.


c) If the fuel burns to 100% completion, the composition of the exhaust gas stream will be 0 mol % methane, 0 mol % ethane, 0 mol % ethylene, and 100 mol % water.

How much KNO3 must be
dissolved in 50 g of water to
yield a saturated solution at
50°C?

Answers

Answer:

The solubility of KNO3 in water increases with temperature. At 50°C, the solubility of KNO3 in water is 34 g/100 g water. This means that at 50°C, 100 g of water can dissolve up to 34 g of KNO3.

To find out how much KNO3 must be dissolved in 50 g of water to yield a saturated solution at 50°C, we can set up a proportion:

34 g KNO3/100 g water = x g KNO3/50 g water

where x is the amount of KNO3 that must be dissolved in 50 g of water.

Solving for x, we get:

x = (34 g/100 g) x 50 g

x = 17 g

Therefore, 17 g of KNO3 must be dissolved in 50 g of water to yield a saturated solution at 50°C.
