There must have been 0.10mol of \(C_{2} H_{2} O\) in the container at the beginning.

 \(C_{2} H_{2} O\) + \(2O_{2}\) = \(2CO_{2}\) + \(H_{2} O\)

The above reaction makes it quite evident that 1 mol of \(C_{2} H_{2} O\) combines to create 2 mol of \(CO_{2}\) and \(O_{2}\) is given in excess that \(C_{2} H_{2} O\) alone controls a product's formation. Therefore, here, O is an excess reactant and \(C_{2} H_{2} O\) is a limiting reactant.

It takes 6 times as much \(C_{2} H_{2} O\) to produce 1 mol of \(CO_{2}\) from 0.05 mol of \(C_{2} H_{2} O\).

Now, 0.6 divided by 6 mol of reactant is required for 0.60 moles of \(CO_{2}\)to produce, which translates to

moles of \(C_{2} H_{2} O\) = 0.6/6 = 0.1 mol .

Therefore, \(C_{2} H_{2} O\) must have been present in the container in an initial concentration of 0.10mol.

Williamson ether synthesis would give a poor yield of product as the halide is on a 2° carbon. is true about the synthesis of 1-isopropoxy-1-methylcyclopentane.

The Williamson ether synthesis is a method for the synthesis of ethers using an alcohol and an alkyl halide. The reaction proceeds through a nucleophilic substitution mechanism and the ether product is obtained with the alcohol and halide groups in the anti-Markovnikov orientation. The reactivity of the alkyl halides used in this reaction follows the order: primary > secondary >> tertiary. Therefore, the reaction of a secondary halide such as 2° carbon halide will give a poor yield of product as the reactivity of 2° carbon halide is less compared to primary halide. As a result, the reaction is less efficient and the yield of the product is lower.

The fugacity in atm for pure ethane at 310 K and 20.4 atm is given by the equation: f = 20.4 exp (-Δg1/RT). The change in chemical potential between this state and a second state of ethane where the temperature is constant but the pressure is 24 atm is -0.0911RT.

Fugacity is a measure of the escaping tendency of a component in a mixture, which is defined as the pressure that the component would have if it obeyed ideal gas laws. It is used as a correction factor in the calculation of equilibrium constants and thermodynamic properties such as chemical potential. Here we need to determine the fugacity in atm for pure ethane at 310 K and 20.4 atm and the change in the chemical potential between this state and a second state of ethane where the temperature is constant but the pressure is 24 atm. So, using the formula of fugacity: f = P.exp(Δu/RT) Where P is the pressure of the system, R is the gas constant, T is the temperature of the system, Δu is the change in chemical potential of the system.  Δu = RT ln (f / P)The chemical potential at the initial state can be calculated using the ideal gas equation as: PV = nRT    

=>  P

= nRT/V

=> 20.4 atm

= nRT/V

=> n/V

= 20.4/RT The chemical potential of the system at the initial state is:

Δu1 = RT ln (f/P)

= RT ln (f/20.4) Also, we know that for a pure substance,

Δu = Δg. So,

Δg1 = Δu1 The change in pressure is 24 atm – 20.4 atm

= 3.6 atm At the second state, the pressure is 24 atm.

Using the ideal gas equation, n/V = 24/RT The chemical potential of the system at the second state is: Δu2 = RT ln (f/24) = RT ln (f/24) The change in chemical potential is Δu2 – Δu1 The change in chemical potential is

Δu2 – Δu1 = RT ln (f/24) – RT ln (f/20.4)

= RT ln [(f/24)/(f/20.4)]

= RT ln (20.4/24)

= - 0.0911 RT Therefore, the fugacity in atm for pure ethane at 310 K and 20.4 atm is:

f = P.exp(Δu/RT)

=> f

= 20.4 exp (-Δu1/RT)

=> f

= 20.4 exp (-Δg1/RT) And, the change in the chemical potential between this state and a second state of ethane where the temperature is constant but pressure is 24 atm is -0.0911RT. Therefore, the fugacity in atm for pure ethane at 310 K and 20.4 atm is given by the equation: f = 20.4 exp (-Δg1/RT). The change in chemical potential between this state and a second state of ethane where the temperature is constant but the pressure is 24 atm is -0.0911RT.

A student measured a cylinder to have a length of 4.21 cm and a diameter of 1.29 cm. The volume of the cylinder is  \(V \approx 5.5 \mathrm{~cm}^3\).

\(V=\pi\left(\frac{d}{2}\right)^2 h=\pi \cdot\left(\frac{1.29}{2}\right)^2 \cdot 4.21 \approx 5.50239 \mathrm{~cm}^3\)

A cylinder's volume refers to the amount of interior room it has to hold a given quantity of material. To put it another way, a cylinder's volume is how much it can hold. You can store any one of the three forms of matter—solid, liquid, or gas—within the confines of a cylinder. You cannot hold any liquid, solid, or gas in a two-dimensional cylinder, hence this capacity can only be observed in a three-dimensional cylinder.

Under ordinary circumstances, a gas that takes up 75 ml is heated to 17 °C and the pressure is lowered to 0.97 atm. The gas has now filled a capacity of 79.9 ml.

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

(P₁ × V₁) / T₁ = (P₂ × V₂) / T₂

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

We are given P₁ = 1 atm (standard conditions), V₁ = 75 ml, T1 = 273 K (standard conditions + 0°C), P2 = 0.97 atm, and T₂ = 17°C + 273 = 290 K.

Substituting these values into the formula and solving for V₂, we get:

(1 atm × 75 ml) / 273 K = (0.97 atm × V₂) / 290 K

Simplifying and solving for V2, we get:

V₂ = (1 atm × 75 ml × 290 K) / (273 K × 0.97 atm) = 79.9 ml

Therefore, the new volume occupied by the gas is approximately 79.9 ml (three significant figures).

Answer:

\(\boxed {\boxed {\sf 56 \ Joules}}\)

Explanation:

We are given the mass, specific heat, and temperature, so we must use this formula for heat energy.

\(q=mc \Delta T\)

The mass is 5 grams, the specific heat capacity is 0.14 Joules per gram degree Celsius. Let's find the change in temperature.

We know the variables and can substitute them into the formula.

\(m= 5 \ g \\c= 0.14 \ J/ g \ \textdegree C \\\Delta T= 80 \ \textdegree C\)

\(q= (5 \ g )( 0.14 \ J/ g \ \textdegree C ) ( 80 \ \textdegree C)\)

Multiply the first numbers. The grams will cancel.

\(q= 0.7 \ J/ \textdegree C(80 \ \textdegree C )\)

Multiply again. This time the degrees Celsius cancel.

\(q= 56 \ J\)

56 Joules of heat are needed.

Question: an oil drum weights 11.8kg. when it is filled, pentane it weighs 55.32kg. how many molecules of pentane c5h12 exist in this oil drum?

Answer:

3.64×10²⁶ molecules

Explanation:

Applying,

n = M/M.M................... Equation 1

Where n = number of moles of pentane, M = mass of pentane, M.M = reacting mass of pentane

From the question,

Given: M = 55.32-11.8 = 43.52 kg = 43520 g

Constant: M.M of octane (C₅H₁₂) = [(12×5)+(1×12)] = 60+12 = 72 g/mol

Substitute these values into equation 1

n = 43520/72

n = 604.44 moles

Therefore,

number of molecules = n×(6.02×10²³)

number of molecules = 604.44(6.02×10²³)

number of molecules = 3.64×10²⁶ molecules

It appears that the straw in the glass of water is bent or refracted at the water-air interface. This is a result of the phenomenon known as refraction. Refraction occurs when light travels from one medium to another with a different optical density, causing the light rays to change direction.

Based on the provided image from BrainPOP Science, it appears that the straw in the glass of water is bent or refracted at the water-air interface. This is a result of the phenomenon known as refraction. Refraction occurs when light travels from one medium to another with a different optical density, causing the light rays to change direction.

In this case, as the light passes from the water to the air, it undergoes refraction because the speed of light is different in water compared to air. The change in speed causes the light rays to bend as they cross the water-air boundary. This bending of light is what makes the straw appear bent or displaced when viewed through the glass of water.

The phenomenon of refraction is a common optical effect and can be observed in various situations where light passes through different mediums with varying optical properties.
