The energy of combustion for one mole of butane to be approximately 2888.81 kJ/mol.

To calculate the energy of combustion for one mole of butane (C4H10), we need to use the information provided and apply the principle of calorimetry.

First, we need to convert the mass of the butane sample from grams to moles. The molar mass of butane (C4H10) can be calculated as follows:

C: 12.01 g/mol

H: 1.01 g/mol

Molar mass of C4H10 = (12.01 * 4) + (1.01 * 10) = 58.12 g/mol

Next, we calculate the moles of butane in the sample:

moles of butane = mass of butane sample / molar mass of butane

moles of butane = 0.367 g / 58.12 g/mol ≈ 0.00631 mol

Now, we can calculate the heat released by the combustion of the butane sample using the equation:

q = C * ΔT

where q is the heat released, C is the heat capacity of the calorimeter, and ΔT is the change in temperature.

Given that the heat capacity of the bomb calorimeter is 2.36 kJ/°C and the change in temperature is 7.73 °C, we can substitute these values into the equation:

q = (2.36 kJ/°C) * 7.73 °C = 18.2078 kJ

Since the heat released by the combustion of the butane sample is equal to the heat absorbed by the calorimeter, we can equate this value to the energy of combustion for one mole of butane.

Energy of combustion for one mole of butane = q / moles of butane

Energy of combustion for one mole of butane = 18.2078 kJ / 0.00631 mol ≈ 2888.81 kJ/mol

Therefore, the energy of combustion for one mole of butane is approximately 2888.81 kJ/mol.

In conclusion, by applying the principles of calorimetry and using the given data, we have calculated the energy of combustion for one mole of butane to be approximately 2888.81 kJ/mol.

1940K and 1939K Isotopes are two forms of the same element that have different numbers of neutrons in the nucleus. This means same symbol, and same atomic number (subscript), but different mass number (superscript).

The de Broglie wavelength of an electron traveling at 1.59×105m/s is  0.4547 x 10⁻⁹ m.

The elementary electric charge of the electron is a negative one, making it a subatomic particle. Due to their lack of known components or substructure, electrons, which are part of the first generation of the lepton particle family, are typically regarded to be elementary particles.

The length scale at which a particle's wave-like characteristics are significant is indicated by its de Broglie wavelength. The symbol or dB is typically used to indicate the De Broglie wavelength. The de Broglie wavelength for a particle with momentum p is given by dB = hp.

λ = h/mv

Where,

λ = wavelength of electron

m = mass of electron = 9.11e-31 kg

v = speed of electron = 1.59 × 10⁵ m/s

h = constant

Therefore,

λ = (6.626x10⁻³⁴J-s) ÷  [(9.11e-31 kg) (1.59 x 10⁵ m/s)]

λ = 0.4547 x 10⁻⁹ m

Thus, The de Broglie wavelength of an electron traveling at 1.59×105m/s is  0.4547 x 10⁻⁹ m.

The relationship between the rate of diffusion r, and d is r ∝ 1/√d.

The relationship between the rate of diffusion (r) and the density of a gas (d) can be explained using Graham's law of diffusion. According to this law, the rate of diffusion of a gas is inversely proportional to the square root of its density. Mathematically, it can be expressed as:

r ∝ 1/√d

where the symbol '∝' represents 'proportional to'. The constant of proportionality (k) can be introduced to this equation as:

r = k/√d

This equation shows that as the density of a gas increases, its rate of diffusion decreases. This is because denser gases have more molecules per unit volume and thus, they experience greater intermolecular collisions that hinder their movement. Therefore, it requires more energy for them to diffuse through a medium compared to less dense gases.

The relationship between the rate of diffusion and density is particularly important in understanding the behavior of gases in different environments. For instance, in a gas chromatography column, the rate of diffusion of a gas determines how quickly it moves through the column and separates from other components. Similarly, in the Earth's atmosphere, the rate of diffusion of greenhouse gases such as carbon dioxide affects their concentration and hence, their impact on climate change.

Answer:

3.5154 g/mL

Explanation:

You will need to use the equation Density = Mass/Volume. You are given mm(can be used to find volume) of a cube and kg(mass). Since your answer is in g and mL we should convert it to those sizes. First we want cm so we will divide the 127.58 mm to cm getting 12.758 cm. We want to cube it since we are finding the whole area of a cube( 12.758*12.758*12.758) which will equal 2076.58 cm^3. We know that 1 mL is equal to 1 cm^3, so we can take our 2076.58 cm^3 and label them as mL(which is what we want). Then we know that there are 1000g in 1 kg, so if we multiply the 7.3 kg, we get 7300g. Finally use the equation Density = Mass/Volume to get your answer. 7300g/2076.58mL = 3.5154 g/mL.

The mass of water that can be obtained is 2.2 g of water.

We know that in the case that we have here, we are going to depend on the stoichiometry of the reaction and this is very important in the determination of the amount of the water that can be formed.

Now we can see that the reaction equation can be written from the fact that; \(2H_{2} (g) + O_{2} (g) ---- > 2H_{2} O(g)\). Then we can see that in this kind of chemical reaction we have to apply the stoichiometry.

Number of moles of the hydrogen = 14.8g/2 g/mol = 7.4 moles

Number of moles of oxygen = 34.8 g/32 g/mol = 1.1 moles

Given that 2 moles of hydrogen reacts with 1 mole of oxygen

7.4 moles of hydrogen reacts with 7.4 * 1/2

The complete form of the table is:

1. For pH = 3.78:

[H₂O¹⁺] can be calculated using the formula [H₂O¹⁺] = 10^(-pH).

[H₂O¹⁺] = 10^(-3.78) = 1.58 x 10⁻⁴ M.

To find pOH, use the equation pOH = 14 - pH.

pOH = 14 - 3.78 = 10.22.

Since the concentration of [OH¹⁻] can be obtained by using the relation [OH¹⁻] = 10^(-pOH).

[OH¹⁻] = 10^(-10.22) = 6.31 x 10⁻¹¹ M.

Based on the pH value, this solution is acidic.

2. For [H₂O¹⁺] = 3.89 x 10⁻⁴ M:

Given the concentration of [H₂O¹⁺],  calculate the pH.

pH can be determined using the equation pH = -log[H₂O¹⁺].

pH = -log(3.89 x 10⁻⁴) ≈ 11.22.

The pOH can be calculated using the equation pOH = 14 - pH.

pOH = 14 - 11.22 ≈ 2.78.

Since the concentration of [OH¹⁻] is related to pOH as [OH¹⁻] = 10^(-pOH).

[OH¹⁻] = 10^(-2.78) ≈ 2.03 x 10⁻¹¹ M.

Based on the pH value, this solution is basic.

3. For pOH = 5.19:

To calculate the concentration of [OH¹⁻], use the relation [OH¹⁻] = 10^(-pOH).

[OH¹⁻] = 10^(-5.19) ≈ 6.05 x 10⁻⁶ M.

To find the pH, we can use the equation pH = 14 - pOH.

pH = 14 - 5.19 ≈ 8.81.

Since the pH is greater than 7, this solution is basic.

4. For [OH¹⁻] = 4.88 x 10⁻¹⁰ M:

Given the concentration of [OH¹⁻], calculate the pOH.

pOH = -log[OH¹⁻].

pOH = -log(4.88 x 10⁻¹⁰) ≈ 9.31.

To find the pH, use the equation pH = 14 - pOH.

pH = 14 - 9.31 ≈ 4.69.
