Answer:
The correct order of the steps to making electricity with a generator is:
Mechanical energy spins a turbine.A turbine spins a magnet creating disturbances in a magnetic field.A magnetic field moves electrons in a conductor.Electrons create a current of electricity.First, mechanical energy is used to spin a turbine, which is typically connected to a magnet. As the turbine spins the magnet, it creates disturbances in a magnetic field. These disturbances then cause the magnetic field to move electrons in a nearby conductor, such as a wire. This movement of electrons creates a flow of electrical current through the wire, which can be used to power various devices. Therefore, the final step is the production of electricity, as electrons flow through the conductor and create a current of electricity.

What is meant by volume of gas?Volume of gas can be defined as the space occupied by gaseous particles at standard temperature and pressure conditions.
As we know, (P₁V₁)/T1 = (P₂ V₂)/ T₂
P₁, V₁, and T₁ are initial pressure, volume, and temperature, and P₂, V₂, and T₂ are final pressure, volume, and temperature.
T₁ = 12°C + 273.15 = 285.15 K

Consider the following reaction.
2NO2(g)⇌N2O4(g)
When the system is at equilibrium, it contains NO2
at a pressure of 0.716 atm
, and N2O4
at a pressure of 0.0513 atm
. The volume of the container is then reduced to half its original volume. What is the pressure of each gas after equilibrium is reestablished?
The pressure of NO2 after equilibrium is re-established is 1.432 atm and that of N2O4 is 0.1026 atm.
How do you calculate the pressure of each gas after equilibrium is reestablished?Writing the equilibrium expression for the specified reaction is the first step.
Kp is equal to (P(N2O4))²/(P(NO2))²
Next, using the partial pressures of NO2 and N2O4 at equilibrium provided, we must determine the value of the equilibrium constant Kp.
Kp = (0.0513)2 / (0.716)2 = 0.00201
The new equilibrium partial pressures of NO2 and N2O4 are P'(NO2) and P'(N2O4), respectively. Then:
P'(NO2)=2 x 0.716 = 1.432 atm
P'(N2O4) is equal to two times 0.0513 atm.
Last but not least, we may determine whether the new equilibrium partial pressures satisfy the expression for the equilibrium constant:
Kp = (P'(N2O4))²/ (P'(NO2)² = (0.1026) (0.1026)² / (1.432) (1.432)² = 0.00201
As a result, when equilibrium is restored, the pressures of NO2 and N2O4 are both 1.432 atm for NO2 and 0.1026 atm for N2O4, respectively.

The most common source of copper (Cu) is the mineral chalcopyrite (CuFeS2). How many kilograms of chalcopyrite must be mined to obtain 400.
g of pure Cu
Express your answer to three significant figures and include the appropriate
units.
To solve this problem, we need to use the molar mass of copper and the stoichiometry of the balanced equation to determine how much chalcopyrite is needed to produce 400 g of pure copper.
The molar mass of copper is 63.55 g/mol, which means that 1 mole of copper contains 63.55 grams of copper. Using this information, we can convert 400 g of copper to moles:
400 g Cu x (1 mol Cu/ 63.55 g Cu) = 6.292 mol Cu
From the balanced equation of the reaction, we know that 1 mole of chalcopyrite (CuFeS2) produces 1 mole of copper. Therefore, we need to mine the same number of moles of chalcopyrite as the number of moles of copper required.
To determine the number of moles of chalcopyrite needed, we can use the molar mass of chalcopyrite:
Molar mass of CuFeS2 = (1 x atomic mass of Cu) + (1 x atomic mass of Fe) + (2 x atomic mass of S)
= (1 x 63.55 g/mol) + (1 x 55.85 g/mol) + (2 x 32.06 g/mol)
= 183.53 g/mol
Now we can convert the moles of copper to moles of chalcopyrite:
6.292 mol CuFeS2 x (183.53 g CuFeS2/ 1 mol CuFeS2) = 1154.4 g or 1.1544 kg of CuFeS2
Therefore, we need to mine 1.1544 kg of chalcopyrite to obtain 400 g of pure copper.
Suppose that Daniel has a 3.00
L bottle that contains a mixture of O2

, and CO2

mol N2
and that the partial pressure of CO2
is 0.250
atm. If the temperature is 273
K, what is the partial pressure of O2
?
Answer:
To solve this problem, we can use the equation for the ideal gas law:
PV = nRT
where P is the pressure, V is the volume, n is the number of moles, R is the gas constant, and T is the temperature.
First, we need to find the total number of moles of gas in the bottle. We know that the bottle contains 0.270 mol of N2, and we can find the number of moles of CO2 by using the partial pressure and the total pressure:
P(CO2) / P(total) = n(CO2) / n(total)
0.250 atm / 4.90 atm = n(CO2) / n(total)
n(CO2) = 0.0128 mol
The total number of moles is then:
n(total) = n(O2) + n(N2) + n(CO2) = n(N2) + n(CO2) + n(O2) = 0.270 mol + 0.0128 mol + n(O2)
n(total) = 0.2828 mol + n(O2)
Next, we can use the ideal gas law to find the number of moles of O2:
PV = nRT
n(O2) = PV / RT
We can rearrange this equation to solve for P(O2):
P(O2) = n(O2)RT / V
We know that R = 0.08206 L·atm/mol·K and T = 273 K. We also know that P(total) = 4.90 atm, and we can find the volume of the bottle by using the given information that it contains 3.00 L:
n(O2) = P(O2) V / RT
0.2828 mol + n(O2) = P(O2) (3.00 L) / (0.08206 L·atm/mol·K) (273 K)
0.2828 mol + n(O2) = 35.75 P(O2)
We can use the information that the partial pressure of CO2 is 0.250 atm to find the partial pressure of N2:
P(N2) = P(total) - P(O2) - P(CO2) = 4.90 atm - P(O2) - 0.250 atm
P(N2) = 4.65 atm - P(O2)
Finally, we can use the fact that the total pressure is the sum of the partial pressures to find P(O2):
P(total) = P(O2) + P(N2) + P(CO2)
4.90 atm = P(O2) + (4.65 atm - P(O2)) + 0.250 atm
4.90 atm = 4.90 atm
Solving for P(O2), we get:
P(O2) = 0.990 atm
Therefore, the partial pressure of O2 is 0.990 atm.
Type at least 3 adaptions they have and explain how these adaptions help them survive in their environments
White-tailed deer have eyes on the sides of their heads. This provides them with a broad range of view for identifying predators.
What is adaptation?Adaptation has three meanings in biology. For starters, natural selection is a dynamic evolutionary process that adapts organisms towards their environment, increasing their evolutionary fitness.
Second, it is a condition attained by the population as a result of that process. The fawns depend on their behavioral and physical adaptations to survive their first few weeks. White-tailed deer are quick and nimble. White-tailed deer have eyes on the sides of their heads. This provides them with a broad range of view for identifying predators.
