The mileage of the Toyota Prius hybrid in miles per gallon would be 49.39 miles/gallon.

A unit of measurement is a specified magnitude of a quantity that is established and used as a standard for measuring other quantities of the same kind. It is determined by convention or regulation.

As given in the problem a Toyota Prius hybrid gets 21 kilometers per liter in highway driving.

1 kilometers =  0.621 miles

21 kilometers = 21 ×  0.621 miles

                      =13.04 miles

1 liter =  0.264 gallon

The mileage in miles per gallon = 13.04 miles / 0.264 gallon

                                                     = 49.39 miles/gallon

Thus, the mileage of the Toyota Prius hybrid in miles per gallon would be 49.39 miles/gallon.

Answer:

59.8 g of PbSO₄.

Explanation:

The balanced equation for the reaction is given below:

Pb + PbO₂ + 2H₂SO₄ —> 2PbSO₄ + 2H₂O

Next, we shall determine the mass of PbO₂ that reacted and the mass of PbSO₄ produced from the balanced equation. This can be obtained as follow:

Molar mass of PbO₂ = 207 + (16×2)

= 207 + 32

= 239 g/mol

Mass of PbO₂ from the balanced equation = 1 × 239 = 239 g

Molar mass of PbSO₄ = 207 + 32 + (16×4)

= 207 + 32 + 64

= 303 g/mol

Mass of PbSO₄ from the balanced equation = 2 × 303 = 606 g

SUMMARY:

From the balanced equation above,

239 g of PbO₂ reacted to produce 606 g of PbSO₄.

Finally, we shall determine the mass of PbSO₄ that will be produced by the reaction of 23.6 g of PbO₂. This can be obtained as follow:

From the balanced equation above,

239 g of PbO₂ reacted to produce 606 g of PbSO₄.

Therefore, 23.6 g of PbO₂ will react to produce = (23.6 × 606) / 239 = 59.8 g of PbSO₄.

Thus, 59.8 g of PbSO₄ were obtained from the reaction.

2. Which is the volume of 3.20 moles of O₂?

We are told that at STP one mol of any gas occupies 22.4 L. We will use that relationship to find the volume occupied by 3.20 moles of O₂.

1 mol of O₂ = 22.4 L

volume of O₂ = 3.20 moles of O₂ * 22.4 L/(1 mol of O₂)

volume of O₂ = 71.7 L

Answer: 3.20 moles of O₂ occupies 71.7 L

7. Which is the volume of 100. g of O₂?

In this case we will use the same relationship, but we are given grams instead of moles. So first we have to convert the mass in grams into moles. To do that we use the molar mass of O₂.

atomic mass of O = 16.00 amu

molar mass of O₂ = 2 * 16.00

molar mass of O₂ = 32.00 g/mol

Once that we know that the mass of 1 mol of O₂ is 32.00 g, we can find the number of moles that we have in 100. g of it.

moles of O₂ = mass of O₂ /(molar mass of O₂)

moles of O₂ = 100. g/(32.00 g/mol)

moles of O₂ = 3.13 moles

Finally we can find the volume that 3.13 moles of O₂ occupies (remember that 1 mol of any gas occupies 22.4 L at STP).

volume of O₂ = 3.13 moles * 22.4 L/(1 mol)

volume of O₂ = 70.1 L

Answer: 100. g of O₂ occupies 70.1 L

Solid Snake (75 kg) carries 18 kg of equipment. If Solid Snake climbs 27 flights of stairs, each 5.5 m in height, the work done against gravity is 135.34 kJ (c).

In physics, work is the energy transferred to or from an object via the application of force along a displacement.

In this problem, the force that does the work is the one that opposes the weight.

Solid Snake is 75 kg and is carrying 18 kg of equipment. The total mass is:

m = 75 kg + 18 kg = 93 kg

We can calculate the weight using Newton's second law of motion.

F = m . g = 93 kg . 9.8 m/s² = 911.4 N

Solid Snake climbs 27 flights of stairs, each 5.5 m in height.

27 . 5.5 m = 148.5 m

We will use the definition of work.

w = F . s = (911.4 N) . (148.5 m) . (1 kJ/1000 J) = 135.34 kJ

Explanation:

what is your Question plese

Answer:

Volume of the reaction vessel is increased - shift to the left

The reaction is cooled down - shift to the right

H2 is added to the system - shift to the right

The pressure of the system is decreased - shift to the left

A catalyst is added to the system - no change

Water is removed from the system - shift to the right

Explanation:

When a constraint such as a change in temperature, pressure or volume is imposed on a reaction system in equilibrium, the equilibrium position will shift in such a way as to annul the constraint.

When the volume of a reaction system is increased, the equilibrium position shifts in the direction in which there is the highest total volume. This is the left hand side.

Since the reaction is exothermic (heat is given out) when the reaction is cooled down, the forward reaction is favoured.

Adding of reactants shifts the equilibrium position to the right hand side hence when H2 is added, the equilibrium position shifts to the right.

Decreasing the pressure shifts the equilibrium position to the direction of higher total volume hence the equilibrium shifts to the left when pressure is decreased.

A catalyst has no effect on the equilibrium position. It increases the rate of forward and reverse reaction to the same extent hence the equilibrium position is unaffected.

Removal of water from the system increases the rate of forward reaction since a product is being removed from the reaction system.

The standard reaction Gibbs free energy (ΔGrxn°) using the given partial pressures is -60,200 J/mol.

Energy is the ability to do work, whether it be in the form of heat, light, electrical, chemical, nuclear, or mechanical energy. It is the capacity to move, change, or transform matter, and is essential for all processes of life.

ΔGrxn = -RT ln Kp
Where R is the universal gas constant (8.314 J/mol K) and T is the temperature (25°C).
Therefore, ΔGrxn = -(8.314)(298) ln (2.26 x 10⁴)
= -20,067 J/mol
Now we need to calculate the standard reaction Gibbs free energy (ΔGrxn°) using the given partial pressures:
ΔGrxn° = ∑nΔGrxn°products - ∑nΔGrxn°reactants
ΔGrxn°products = -RT ln (PCH₃OH)
= -(8.314)(298) ln (1.0)
= 0 J/mol
ΔGrxn°reactants = -RT ln (PCO) - 2(RT ln (PH2))
= -(8.314)(298) ln (0.010) - 2(8.314)(298) ln (0.010)
= -60,200 J/mol
Therefore, ΔGrxn° = ∑nΔGrxn°products - ∑nΔGrxn°reactants
= 0 - (-60,200)
= -60,200 J/mol
Finally, ΔGrxn = ΔGrxn° + RT ln Q
= -60,200 + (8.314)(298) ln (1.0)
= -60,200 J/mol.

The equation C2H4(g) + H2(g) + C2H6(g) → Caco3(s) + Cao(s) + CO2(g) shows an increase in entropy due to the formation of a gas as a product. Option A

In this equation, the reactants on the left-hand side consist of gases (C2H4 and H2), while the products on the right-hand side include a solid (Caco3) and a gas (CO2).

When a reaction involves a change from gaseous to solid or liquid states, there is typically a decrease in entropy because the particles become more ordered and constrained in the solid or liquid phase.

Conversely, when a reaction involves the formation of gases, there is generally an increase in entropy because gases have higher degrees of molecular motion and greater freedom of movement compared to solids or liquids.

In the given equation, the reactants include three gaseous compounds (C2H4, H2, and C2H6), and one of the products is a gas (CO2). Therefore, the overall entropy of the system increases during this reaction.

The equation Fe(s) + S(s) → FeS(s) does not show an increase in entropy. Both the reactants (Fe and S) and the product (FeS) are solids. Since solids have lower entropy compared to gases or liquids, the entropy of the system does not increase in this reaction. Option A
