a copper ore contains 3.00% of copper carbonate, CuCO3, by mass. Which mass of copper would be obtained from 1 tonne of the ore?
A 1.91kg B 3.71kg C 15.3kg D 58.4kg
Answers
Answer:
(c) 15.39 kg of copper present in 1tonne of ore.
Explanation:
We are given that ore contains 3% of copper carbonate
1tonne = 1000kg
3% of copper carbonate in 1000kg of ore will be
= \(\frac{3}{100}*1000\) = 30kg
30 kg of copper carbonate is present in ore
CuCO3 has 63.5g of cupper present in it
molar mass of CuCO3 = 123.5
so the percentage of copper present in CuCO3
= \(\frac{63.5}{123.5}*100\) = 51.3% of copper present per kg CuCO3
Now
amount of copper present in 30kg of CuCO3
= \(\frac{51.3}{100}* 30\) = 15.39kg
15.39 kg of copper present in 1tonne of ore
The mass of copper obtained from 1 tonne of the ore is 15.4 kg
The copper ore has 3% of copper carbonate by mass.
The mass of copper carbonate in 1 tonne of the ore can be calculated below.
1000 kg = 1 tonne
Therefore,
mass of copper carbonate = 3 /100 × 1000 = 30 kg
atomic mass of copper = 63.5 g
molar mass of CuCO₃ = 123.55 g
123.55 g of CuCO₃ gives 63.5 g of copper
30, 000g of CuCO₃ will give ? of copper
cross multiply
mass of copper = 30,000 × 63.5 / 123.55
mass of copper = 1905000 / 123.55 = 15418.8587616 g
mass of copper = 15418.8587616 / 1000 ≈ 15. 4 kg

Answer:
addition polymerization
Explanation:
In addition polymerization, the monomers are simply joined to each other to form a polymer having the same empirical formula as the monomer but of higher relative molecular mass. The monomers in addition polymerization are usually simple unsaturated molecules such as alkenes.
We can deduce the reaction to be an addition polymerization because of the the attachment of n to both the unsaturated monomer and the saturated polymer without the loss of any small molecule. If it was a condensation polymerization, there would have been an accompanying loss of a small molecule such as water.

How much energy would it take to melt 33.06 g of Ice How much energy is needed for that water to evaporate?
Answers
The amount of energy that must be added to a solid substance (usually in the form of heat) in order to cause a change in its physical state and turn it into a liquid (while the environment's pressure is maintained) is known as enthalpy of fusion. The amount of energy taken by water to evaporate is 74,444.4 J.
The amount of heat required to vaporize a specific amount of liquid at a fixed temperature is known as the Heat of Vaporisation. The kinetic energy of the steam is demonstrated to be higher than the kinetic energy of the fluid when the solutions of the vapor and liquid states are compared.
Let the temperature be 0°C.
The heat needed is:
q = n ×ΔH
n = Mass / Molar mass = 33.06 / 18.02 = 1.83
Enthalpy of fusion = 6.02 kJ / mol
q = 1.83 × 6.02 = 11.0166 kJ = 11016.6 J
Enthalpy of vaporization of water = 40.68 kJ / mol
q = 1.83 × 40.68 = 74.44 kJ = 74,444.4 J

Answers
The entire energy of all internal molecular motion makes up an object's heat.The thermal energy or average heat of the molecules in a substance is measured by temperature.It is a measurement of the quantity of atoms times the energy that each atom possesses.
How do heat and temperature relate to one another?
Let's now think about the connection between heat and temperature.The temperature rises as materials are heated.In other words, when a substance receives energy, the molecules that make up that substance move more quickly. The energy that is transferred from a hot object to a cold object is called heat.A measurement of an object's hotness or coolness is its temperature.Both the specific heat equation (Q=mcT Q = m c T) and the latent heat equation (Q=ml Q = m l) relate these two numbers. Meaning that it will require more heat to raise a temperature by one degree the more mass you govern.In contrast, the specific heat capacity would remain constant regardless of the mass used to raise the temperature by one degree Celsius.Heat capacity=mass*specific heat capacity is the relationship between the two. Temperature fluctuations are typically a good indicator of changes in heat.A group of atoms often move more quickly and become hotter when you add energy to them.Similar to this, when energy is removed from a group of atoms, they typically move less and become cooler. Heat is a measure of change, never a quality that an item or system possesses.It is categorized as a process variable as a result.Temperature can be expressed in Celsius (°C), Kelvin (K), Fahrenheit (°F), or Rankine units and describes the average kinetic energy of molecules inside a substance or system (R). The quantity of energy produced as a substance's temperature rises is referred to as heat.The right response is therefore option d, which states that heat is the energy transfer caused by a temperature differential. Heat is exchanged between two objects when their temperatures differ.When the two items reach the same temperature, the cooler object becomes warmer.Always, heat energy moves from a hot object to a cooler object. The average measurement of a substance's heat energy is its temperature.A body's temperature determines how hot or cold it is.The material becomes heated when a body's temperature rises.To learn more about heat and temperature refer

What pillar of sustainability is broken by recycling
electronics in India? Should the US make a law that electronics can
only be recycled in the US?
Answers
The pillar of sustainability broken by recycling electronics in India is environmental sustainability. Implementing a law that restricts electronics recycling to the US would not necessarily be the most effective solution, as it overlooks the complex global dynamics of electronic waste management.
Recycling electronics in India often involves improper disposal methods, such as burning or dismantling without proper safety measures. This leads to environmental pollution, including the release of hazardous substances into the air, soil, and water, thus violating the principle of environmental sustainability.
However, simply mandating that electronics can only be recycled in the US may not be the most optimal solution. Electronic waste is a global issue, and restricting recycling to a single country disregards the fact that electronic products are manufactured and consumed worldwide. A more comprehensive approach to addressing electronic waste would involve international cooperation, strict regulations, and monitoring of recycling practices to ensure they meet environmental standards.
Efforts should focus on improving recycling practices globally, including promoting responsible electronic waste management, developing sustainable recycling infrastructure in multiple countries, and encouraging the adoption of safe and environmentally friendly recycling practices. This approach would foster global sustainability and address the challenges associated with electronic waste disposal more effectively than a geographically limited restriction.

Assume that cell death is negligible ("mu" g ≫ kd) and ethanol consumption for product formation is negligible. Sterile medium feeding into the bioreactor contains an ethanol concentration of 22 g/L. We will operate the bioreactor to maximize the biomass productivity. Assume the kinetics of cell growth on ethanol is of the Monod type, with:
"mu" m = 0.65 h-1 KS = 0.045 g/L
YX/S = 0.40 g cells/g ethanol YO2/S = 1.5 g O2/g ethanol

(h) Can sufficient oxygen be provided to the bioreactor to operate at Dopt? Explain your answer.
Answers
The simplified form of the differential cell mass balance equation is dX/dt = μmX/(KS + S).
(a) The simplified form of the differential cell mass balance can be derived as follows:
dX/dt = D(XF - X) - μX
Where:
dX/dt is the rate of change of cell mass (g/L-h)
D is the dilution rate (h-1)
XF is the concentration of cell mass in the feed (g/L)
X is the concentration of cell mass in the bioreactor (g/L)
μ is the specific growth rate (h-1)
(b) To find the optimal dilution rate (Dopt) for maximum cell mass productivity, we set the derivative of cell mass with respect to the dilution rate (dX/dD) equal to zero and solve for D:
dX/dD = 0
(c) The concentration of ethanol substrate in the bioreactor effluent can be calculated using the equation:
Cout = Cin - D/X * X
Where:
Cout is the concentration of ethanol in the effluent (g/L)
Cin is the concentration of ethanol in the feed (g/L)
D/X is the dilution rate (h-1)
(d) The simplified form of the differential substrate mass balance can be derived as follows:
dS/dt = Cin * D - D * S / X
Where:
dS/dt is the rate of change of substrate concentration (g/L-h)
Cin is the concentration of substrate in the feed (g/L)
D is the dilution rate (h-1)
S is the concentration of substrate in the bioreactor (g/L)
X is the concentration of cell mass in the bioreactor (g/L)
(e) The concentration of cell mass in the bioreactor effluent can be calculated using the equation:
Xout = X
(f) The yield coefficient (YX/O2) can be calculated as the ratio of cell mass formed per amount of oxygen consumed:
YX/O2 = (μ/YX/S) * (1/YO2/S)
Where:
μ is the specific growth rate (h-1)
YX/S is the biomass yield coefficient (g cells/g substrate)
YO2/S is the oxygen yield coefficient (g O2/g substrate)
(g) The oxygen uptake rate (OUR) for the chemostat bioreactor can be calculated using the equation:
OUR = D * YO2/S * S
Where:
D is the dilution rate (h-1)
YO2/S is the oxygen yield coefficient (g O2/g substrate)
S is the concentration of substrate in the bioreactor (g/L)
(h) To determine if sufficient oxygen can be provided to the bioreactor to operate at Dopt, we compare the oxygen transfer rate of the equipment (15 g O2/L-h) with the oxygen uptake rate (OUR) calculated in part (g). If the oxygen transfer rate is greater than or equal to the oxygen uptake rate, then sufficient oxygen can be provided. Otherwise, additional oxygen supply or modifications may be needed.

Flaming the neck of the tubes immediately after uncapping and before recapping.
Answers
Sub-culturing, or transferring a small amount of microbial culture from one culture vessel to another, is a common laboratory technique used to maintain and propagate microbial cultures.
Several steps are essential during sub-culturing to prevent contamination and ensure accurate and reliable results.
Flaming the inoculating instrument prior to and after each inoculation is important to sterilize the instrument and prevent cross-contamination between cultures.
The high temperature of the flame kills any residual bacteria on the instrument, ensuring that the subsequent culture is not contaminated with unwanted microbes.
Holding the test tube caps in the hand during transferring is necessary to prevent contamination from the environment.
Placing the caps on the lab bench can cause them to pick up unwanted microbes, which can then be transferred to the culture when the cap is replaced.
Cooling the inoculating instrument prior to obtaining the inoculum is important to prevent heat damage to the microbial culture.
Heat can kill or damage microbes, so cooling the instrument to room temperature before obtaining the inoculum ensures that the microbes are not damaged during the transfer process.
Flaming the neck of the tubes immediately after uncapping and before recapping is essential to prevent contamination of the culture with unwanted microbes in the air.
Flaming the neck of the tube sterilizes the opening, preventing airborne microbes from contaminating the culture during the transfer process.
Overall, these steps are essential to maintain the purity and integrity of microbial cultures during sub-culturing, which is important for accurate and reliable results in microbiology research and diagnosis.

which term refers to a compound that helps maintain a stable ph by binding protons if h concentration begins to rise, and releasing them into solution if h concentration falls?
Answers
The term that refers to a compound that helps maintain a stable pH by binding protons if H+ concentration begins to rise, and releasing them into solution if H+ concentration falls is a buffer. Buffers are substances that are able to resist changes in pH, and are essential for maintaining the proper pH in biological systems. They work by balancing the concentration of H+ ions in a solution, preventing pH from becoming too acidic or too basic.
Buffers are crucial in maintaining the proper pH in many biological systems. pH is a measure of the concentration of H+ ions in a solution, and changes in pH can have drastic effects on biological processes. Buffers are able to maintain a stable pH by acting as both an acid and a base. When H+ ions are added to a solution, buffers are able to absorb these ions, preventing the pH from dropping too much. Similarly, when H+ ions are removed from a solution, buffers are able to release H+ ions, preventing the pH from rising too much. Buffers are found throughout the body, including in the blood, where they help to maintain a stable pH despite changes in metabolic activity.

(answer: [n2o4]
Answers
the flask initially contained only n2o4 at 3.01 atm. after the reaction had reached equilibrium, the equilibrium partial pressure of the no2 was measured to be 0.600 atm. the only 0.66% of the N2O4 reacted at equilibrium.
To answer this question, we can start by writing the equilibrium reaction equation:
N2O4(g) ⇌ 2NO2(g)
The equilibrium constant expression for this reaction is:
Kp = [NO2]² / [N2O4]
We are given that the flask initially contained only N2O4 at 3.01 atm and the equilibrium partial pressure of NO2 was measured to be 0.600 atm. Let's denote the equilibrium partial pressure of N2O4 as x atm.
Using the law of mass action, we can write:
Kp = (0.600)² / x = 0.360 / x
Rearranging, we get:
x = 0.360 / Kp
To find Kp, we can use the given equilibrium partial pressure of NO2 and the initial partial pressure of N2O4:
Kp = (0.600)² / 3.01 = 0.119
Substituting this value into the equation for x, we get:
x = 0.360 / 0.119 = 3.03 atm
Therefore, the equilibrium partial pressure of N2O4 is 3.03 atm.
To find the percent of the reactant that reacted, we can use the initial and equilibrium partial pressures of N2O4:
% Reacted = [(Initial pressure - Equilibrium pressure) / Initial pressure] x 100%
% Reacted = [(3.01 - 3.03) / 3.01] x 100% = 0.66%
Therefore, only 0.66% of the N2O4 reacted at equilibrium.
