The number of moles in container 2 is 33.3moles when the container has 27.32L of gas inside it

The number of moles of gas in container 2 can be calculated using the Ideal Gas Law:  

n = PV/RT  

where n is the number of moles of the gas with known volume,

P is the pressure (assumed to be 1 atm for ideal gases),

V is the volume (27.32 liters),

R is the ideal gas constant (0.0821 L·atm/mol·K) and

T is the temperature (assumed to be 273.15 K).  

Plugging in the values, we get:  

n = (1 atm)(27.32 L)/(0.0821 L·atm/mol·K)(273.15 K)

n = 33.3 mol  

Therefore, there are 33.3 moles of gas in container 2.

Answer:

could occur at any temperature.

Explanation:

The spontaneity of a reaction is what determines whether the reaction will occur or not. A spontaneous reaction occurs easily.

The spontaneity of a reaction is predicted by the sign of ∆G.

When ∆G is positive, the reaction is not spontaneous. When ∆G is negative, the reaction is spontaneous.

Note that;

∆G= ∆H - T∆S

Where;

∆H = Change in enthalpy

∆S = Change in entropy

T= temperature

If ∆H is unfavourable and ∆S is favourable, the reaction can proceed at all temperatures because ∆G will always be negative.

It should be noted that a process that is unfavorable as regards to enthalpy, but favorable with respect to entropy could occur at any temperature.

Enthalpy(∆H) serves as amount of internal energy that a compound has, entropy( ∆S)  on the other hand serves as intrinsic disorder within the system.

However, spontaneity of a reaction determines likely hood of occurrence of a reaction, when the process is spontaneous, it makes the reaction to occurs easily.

We can conclude that whenever enthalpy is unfavourable and entropy of a system is favourable, then the spontaneity will be negative and the reaction will occur at any temperature.

Answer:

P₂ = 3.61 atm

Explanation:

Given data:

Initial pressure of tank = 3.20 atm

Initial temperature = 22.0°C

Final temperature = 60.0°C

Final pressure = ?

Solution:

Initial temperature = 22.0°C (22.0 +273 = 295 K)

Final temperature = 60.0°C (60 +273 = 333)

According to Gay-Lussac Law,

The pressure of given amount of a gas is directly proportional to its temperature at constant volume and number of moles.

Mathematical relationship:

P₁/T₁ = P₂/T₂

Now we will put the values in formula:

3.20 atm / 295 K = P₂/333 K

P₂ = 3.20 atm × 333 K / 295 K

P₂ = 1065.6 atm. K /295 K

Answer: Based on Rock Formation, the student's judgment that Rock 2 is more likely to contain a fossil than Rock 1 is appropriate.

Explanation:

Rocks are classified into three types:

Igneous rocks, metamorphic rocks, and sedimentary rocks.

Rock 1 is an Igneous Rock.

When a fiery, molten rock crystallizes and hardens, it forms igneous rocks (from the Latin root word fire).

Rock 2 is a Sedimentary Rock

At standard surface temperatures, sedimentary rock is developed at or near the Earth's surface by the build-up and lithification of sediment (detrital rock) or by precipitation from suspension (chemical rock).

Under low temperatures and pressure, rock deposits produce sedimentary rocks in the ocean and on the Earth's crust. Plants and animals die and are deposited in a sedimentary deposit.

The following are the reasons why sedimentary rocks are the only rock types that hold fossils:

The burial of deceased plants and animals by additional sediment results in the build-up of minerals from water in bones, which leads to the development of fossils.

As a result, sedimentary rocks are the only rock types that retain fossils.

Option (d), P=ATC=MR=MC, accurately represents the long-run equilibrium condition for perfect competition, reflecting the balance between price and cost for firms operating in a competitive market.

The long-run equilibrium condition for perfect competition is that price (P) is equal to average total cost (ATC), which is also equal to marginal cost (MC), and marginal revenue (MR).

Option (d), P=ATC=MR=MC, best represents the long-run equilibrium condition for perfect competition. In perfect competition, firms operate at the minimum point of their average total cost curve, where price equals both average total cost and marginal cost. This condition ensures that firms are earning zero economic profit and are producing at an efficient level.

In the long run, if firms are earning economic profit, new firms will enter the market, increasing competition and driving prices down. Conversely, if firms are experiencing losses, some firms may exit the market, reducing competition and causing prices to rise. This process continues until firms reach a state where price equals average total cost, marginal cost, and marginal revenue, ensuring a long-run equilibrium.

Therefore, option (d), P=ATC=MR=MC, accurately represents the long-run equilibrium condition for perfect competition, reflecting the balance between price and cost for firms operating in a competitive market.

Ethanoic acid has a chemical formula of CH₃COOH.

The total number of carbon atoms in ethanoic acid is 2.

Answer: 25.0 L

Explanation:

For this problem, we will need to use Boyle's Law.

Boyle's Law: P₁V₁=P₂V₂

Since we are looking for V₂, we can rewrite the equation.

V₂=P₁V₁/P₂

The pressure should be in atm, so let's convert kPa to atm.

P₁=100 kPa=0.99 atm

P₂=200 kPa=1.97 atm

Now that we know the pressure in atm, we can plug it into the equation and solve.

\(V_{2} =\frac{(0.99 atm)(50.0L)}{1.97atm}\)

\(V_{2} =25.0 L\)

If a sample of gas trapped by a moveable piston has a volume of 59.0 L and a pressure of 2.10 atm at 273 K. If the volume of the gas decreases to 13.0 L as the temperature is increased to 325 K the new pressure is 10.4 atm.

To solve this problem, we can use the formula

PV = nRT,

where;

P is pressure,

V is volume,

n is the number of moles of gas,

R is the gas constant, and T is the temperature.

Since we have a trapped sample of gas with a moveable piston, we can assume that the number of moles of gas and the gas constant is constant.

So, we can write:

P\(_1\)V\(_1\) = nRT\(_1\)   

(where P\(_1\)= 2.10 atm, V1 = 59.0 L, and T\(_1\) = 273 K)

P\(_2\)V\(_2\) = nRT\(_2\)    

(where P\(_2\) is the new pressure we want to find, V\(_2\) = 13.0 L, and T\(_2\) = 325 K)

Dividing the two equations, we get:

P\(_2\) = (P\(_1\)V\(_1\)T\(_2\)) / (V\(_2\)T\(_1\))

Substituting the values we have:

P\(_2\) = (2.10 atm x 59.0 L x 325 K) / (13.0 L x 273 K)
P\(_2\) = 10.4 atm

Therefore, the new pressure of the gas is 10.4 atm.

Answer: If 550 ml of gas at 1 atm expands to 960 ml, the pressure will be 0.57 atm.

Explanation:

It is an exercise of Boyle's Law that says: "At constant temperature the volume of a mass of a gas is inversely proportional to the pressure it exerts".

This means that if the volume is doubled the pressure is halved, and if the pressure is increased three times as much, the volume will be one third (1/3) of what it originally was.

The word inversely proportional means that if the pressure increases the volume decreases but proportionally.

550 mL of gas at I atm is expanded to 960 mL. What will the pressure be?

Data:

V₁ = 550 mL

P₁ = 1 atm

V₂ = 960 mL

P₂ = ?

The formula of this law is:

Where

He asks us what the pressure would be after 960 mL, we solve the formula for the final pressure, then

\(\boxed{\bold{P_1V_1=P_2V_2 \iff \ P_2=\frac{P_1V_1}{V_2} }}\)

We substitute our data in the cleared formula and solve:

\(\boxed{\bf{P_2=\dfrac{(1 \ atm \ \times \ 550\not{mL}) }{960\not{mL}} }}\)

\(\boxed{\bf{P_2=0.57 \ atm }}\)

If 550 ml of gas at 1 atm expands to 960 ml, the pressure will be 0.57 atm.

The planet that is nearest to the Sun is Venus. Because of its size and similarity to Earth in composition, it is frequently referred to as Earth's "twin" or "sister" planet. Whether Venus is visible in the morning or evening sky, it is always close to the Sun.

Despite Venus' greater distance from the Sun, Venus is hotter than Mercury. In contrast to the other planets in our solar system, Venus' axis rotates in a clockwise direction. The Moon is the brightest star in the night sky, followed by Venus.

Venus is strange because it rotates in the opposite direction from Earth and most other planets. It rotates fairly slowly as well. About 243 days are required for the Earth to complete one full rotation. Given its closeness to the Sun, a year goes by rapidly.

The number of hamburgers sold on Wednesday is 275.

Let's assume the number of hamburgers sold is x.

According to the given information, the number of cheeseburgers sold is 70 more than the number of hamburgers. So, the number of cheeseburgers sold can be expressed as x + 70.

The total number of hamburgers and cheeseburgers sold is given as 620, so we can set up the following equation:

x + (x + 70) = 620

Combining like terms, we get:

2x + 70 = 620

Subtracting 70 from both sides of the equation:

2x = 550

Dividing both sides by 2:

x = 275

Answer:

It's a chemical change.

Explanation:

The process of burning (as opposed to evaporating) is a chemical reaction, a chemical change. The wax molecules are undergoing a chemical change; they are changing into different molecules by reacting with a substance in the air.

when the temperature is raised to 325 K and the volume is increased to 1.8 L, the gas will occupy a pressure of approximately 1.08 atm.

To solve this problem, we can use the combined gas law equation, which relates the initial and final conditions of a gas when the amount of gas remains constant.

The combined gas law equation is given as:

(P₁ * V₁) / T₁ = (P₂ * V₂) / T₂

where P₁, V₁, and T₁ represent the initial pressure, volume, and temperature, respectively, and P₂, V₂, and T₂ represent the final pressure, volume, and temperature, respectively.

Given

Initial pressure (P₁) = 1.2 atm

Initial volume (V₁) = 0.9 L

Initial temperature (T₁) = 273 K

Final volume (V₂) = 1.8 L

Final temperature (T₂) = 325 K

We need to find the final pressure (P₂).

Substituting the given values into the combined gas law equation, we have:

(1.2 atm * 0.9 L) / 273 K = (P₂ * 1.8 L) / 325 K

Now, we can solve for P₂:

P₂ = (1.2 atm * 0.9 L * 325 K) / (273 K * 1.8 L)

Adiabatic conditions can be written as:

\(TV^{\gamma-1}=constant\)

Then, new temperature is

\(T.(10.4)^{1.67-1}=46.7735\)

\(T.(10.4)^{0.67}=46.7735\)
