The maximum mass of carbon dioxide that could be produced by the chemical reaction is 46.2 g

First, we shall determine the limiting reactant. This obtained as follow

2CH₃(CH₂)₂CH₃ + 13O₂ -> 8CO₂ + 10H₂O

From the balanced equation above,

116 g of CH₃(CH₂)₂CH₃ reacted with 416 g of O₂

Therefore,

48 g of CH₃(CH₂)₂CH₃ will react with = (48 × 416) / 116 = 172.14 g of O₂

From the above calculation, we can see that a higher amount (i.e 172.14 g) of O₂ than what was given (i.e 54.6 g) is needed to react with 48 g of CH₃(CH₂)₂CH₃

Thus, the limiting reactant is O₂

Finally, we shall determine maximum mass of carbon dioxide, CO₂ produced. Details below:

2CH₃(CH₂)₂CH₃ + 13O₂ -> 8CO₂ + 10H₂O

From the balanced equation above,

416 g of O₂ reacted to produce 352 g of CO₂

Therefore,

54.6 g of O₂ will react to produce = (54.6 × 352) / 416 = 46.2 g of CO₂

Thus, the maximum mass of carbon dioxide, CO₂ produced is 46.2 g

Container 3 has the gas stored at the highest temperature.

Temperature is a measure of the average kinetic energy of the particles in a substance. In the given table, it is stated that container 3 has a large number of collisions with container walls, high average kinetic energy, and large number of particles with large spaces between them.

These properties indicate that the gas in container 3 has higher kinetic energy and more vigorous movement compared to the other containers.

Container 1 has a low number of collisions with container walls and a medium average kinetic energy. This suggests that the gas in container 1 has lower energy and less movement than the gas in container 3.

Container 2 has a large number of collisions with container walls, but it also has a small number of particles with little spaces between them. While the collisions may be frequent, the limited number of particles and the lack of space between them may result in lower overall kinetic energy compared to container 3.

Container 4 has few collisions with container walls, low average kinetic energy, and a small number of particles. These properties indicate that the gas in container 4 has the lowest energy and least movement among all the containers.

Answer: The energy of a photon that has a wavelength of 965 nm is \(2.06\times 10^{-16}J\)

Explanation:

The relation between energy and wavelength of light is given by Planck's equation, which is:

\(E=\frac{hc}{\lambda}\)

where,

E = energy of the photon =

h = Planck's constant  = \(6.626\times 10^{-34}Js\)

c = speed of light  = \(3\times 10^8m/s\)

\(\lambda\) = wavelength of light  = 965 nm = \(965\times 10^{-9}m\)     \((1nm=10^{-9}m)\)

Putting in the values we get:

\(E=\frac{6.626\times 10^{-34}\times 3\times 10^8m/s}{965\times 10^{-9}m}=2.06\times 10^{-16}J\)

Thus the energy of a photon that has a wavelength of 965 nm is \(2.06\times 10^{-16}J\)

Answer:

3 atm

1.6 g

Explanation:

Step 1: Given data

Step 2: Find partial pressure (P) of CO₂ gas

We will use Henry's law.

C = k × P

P = C / k

P = 0.1 M / 3.3 × 10⁻² M atm⁻¹

P = 3 atm

Step 3: Calculate the mass of CO₂ gas

The molar mass of carbon dioxide is 44.01 g/mol.

0.355 L × 0.1 mol/L × 44.01 g/mol = 1.6 g

The mass of the asteroid is C. 1.2 x \(10^{12}\) Kg

To find the mass of the other asteroid, we can rearrange the equation for the gravitational force between two objects:

F = (G * m1 * m2) / \(r^{2}\)

where F is the force of gravity, G is the gravitational constant, m1 and m2 are the masses of the two asteroids, and r is the distance between them.

Given that the distance between the asteroids is 75000 m, the force of gravity between them is 1.14 N, and one asteroid has a mass of 8 x \(10^{7}\) kg, we can substitute these values into the equation and solve for the mass of the other asteroid (m2):

1.14 N = (6.67430 × \(10^{-11}\) N \(m^{2}\)/\(Kg^{2}\) * 8 x \(10^{7}\) kg * \(m2\)) / \((75000 m)^{2}\)

Simplifying and solving the equation, we find that the mass of the other asteroid (m2) is approximately 1.2 x \(10^{12}\) kg. Therefore, Option C is correct.

0.191M of Na₂C₂O₄ is the concentration of the original Na₂C₂O₄ solution

Explanation:

The reaction of potassium dichromate, K₂Cr₂O₇ with sodium oxalate, Na₂C₂O₄ in the presence of acid H⁺ is:

K₂Cr₂O₇ + 3Na₂C₂O₄ + 14H⁺ → 2Cr³⁺ + 6CO₂ + 7H₂O + 6Na⁺ + 2K⁺

Thus, 1 mole of K₂Cr₂O₇ reacts with 3 moles of Na₂C₂O₄

Moles of 2.34g of K₂Cr₂O₇ (Molar mass: 294.185g/mol):

2.34g K₂Cr₂O₇ ₓ (1mol / 294.185g) = 7.954x10⁻³ moles K₂Cr₂O₇

In 250mL = 0.250L:

7.954x10⁻³ moles K₂Cr₂O₇ / 0.250L = 0.0318M K₂Cr₂O₇

Moles in 35.7mL = 0.0357L of this solution are:

0.0357L ₓ (0.0318mol / L) = 1.136x10⁻³ moles K₂Cr₂O₇ in solution. As 1 mole of K₂Cr₂O₇ reacts with 3 moles of Na₂C₂O₄, to titrate the moles of K₂Cr₂O₇ in solution you need:

1.136x10⁻³ moles K₂Cr₂O₇ × (3 moles Na₂C₂O₄ / 1 mole K₂Cr₂O₇) =

3.408x10⁻³ moles of Na₂C₂O₄

Explanation:

Historically, phosphorus has been considered to be the primary nutrient limiting phytoplankton growth in freshwater ecosystems.

Answer: B

Explanation:

If the efficiency of a machine increases, it means that the machine is able to convert a higher percentage of its input energy into useful work output.

This could happen due to various factors, such as reducing friction, improving the design of the machine, or using more efficient components. The machine requires less energy input to perform the same amount of work. This could result in cost savings, reduced energy consumption, and lower environmental impact.

The output of the machine increases while the input remains constant. This could result in increased productivity, faster production rates, and improved performance. The wear and tear on the machine may decrease, as it is working more efficiently and experiencing less stress. This could result in longer machine life and reduced maintenance costs. Increasing the efficiency of a machine can have many positive effects, including cost savings, improved performance, and reduced environmental impact.
