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.

How much heat is transferred when the temperature of 36.4g of aluminum
is raised from 32.5°C to 71.6°C?
The amount of heat transferred would be 1269.67 J.
Heat transfer calculationTo calculate the heat transferred (q), we can use the specific heat capacity (c) of aluminum, which is 0.903 J/g°C, the mass of aluminum (m), and the change in temperature (ΔT):
q = m x c x ΔT
where ΔT = (final temperature - initial temperature)
Substituting the given values, we get:
ΔT = 71.6°C - 32.5°C = 39.1°C
m = 36.4 g
c = 0.903 J/g°C
q = 36.4 g x 0.903 J/g°C x 39.1°C
q = 1269.67 J

What is the de Broglie wavelength (in m) of a 0.053 g object moving at a speed of 0.16 m/s?
Answer:
The equation gives the de Broglie wavelength of an object:
λ = h / p
Where λ is the de Broglie wavelength, h is Planck's constant (6.626 x 10^-34 J s), and p is the object's momentum.
The momentum of an object can be calculated using the equation:
p = m * v
Where m is the mass of the object and v is its velocity.
In this case, the mass of the object is 0.053 g, which is equivalent to 0.053 x 10^-3 kg. The velocity of the object is 0.16 m/s. So, the momentum of the object is:
p = (0.053 x 10^-3 kg) * (0.16 m/s) = 8.48 x 10^-6 kg m/s
Substituting this value of momentum and Planck's constant into the de Broglie wavelength equation, we get:
λ = (6.626 x 10^-34 J s) / (8.48 x 10^-6 kg m/s)
Simplifying, we get:
λ = 7.82 x 10^-28 m
Therefore, the de Broglie wavelength of a 0.053 g object moving at a speed of 0.16 m/s is 7.82 x 10^-28 m.

Suppose that Daniel has a 3.00
L bottle that contains a mixture of O2

, and CO2
under a total pressure of 4.90
atm. He knows that the mixture contains 0.270
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.

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.

At STP (Standard Temperature and Pressure), the temperature is 273.15 K (0°C) and the pressure is 1 atm. The molar volume of any gas at STP is 22.4 L/mol.
Explanation:
Therefore, the volume of 225 moles of gas at STP would be:
V = n * V_m
where
V = volume of the gas
n = number of moles of the gas
V_m = molar volume of the gas at STP = 22.4 L/mol
Substituting the values, we get:
V = 225 mol * 22.4 L/mol
V = 5040 L
So the volume of 225 moles of a gas at STP would be 5040 liters.
Answer:
5049 L

Find the ion symbol for the atom and its charge
Answer:
Oxygen 17 isotope with neutral charge
Explanation:
The atom has 8 red protons and 8 black electrons so it is neutral. Since it has 8 protons, it has atomic number of 8, which is oxygen (O).
There are 9 blue neutrons. The mass number = #protons + #neutron = 8 + 9 = 17. Therefore it is the oxygen 17 isotope.
Based on the balanced chemical equation, 2Al(s) + 3H₂SO4(aq) -> Al2(SO4)3(aq) + 3H2(g), how much 4.00 M sulfuric acid is needed to produce 2 moles of aluminum sulfate?
Aluminum sulfate is very non-toxic, having acute and chronic oral LD50 values above 5,000mg/kg (5). Alum, on the other hand, can cause irritation, burns, and breathing problems.
What is Aluminium sulfate used for?
Aluminum sulfate is a crystalline (sand-like) solid that is odorless, white or colorless. It is utilized in sewage treatment, water purification, paper production, and leather tanning. Aluminum sulfate is also known as alum or papermaker's alum; however, the term "alum" refers to any double sulfate salt having the general formula XAl(SO4)212H2O, where X is a monovalent cation such as potassium or ammonium (5).
