Answers
Material requirements planning resource generally substitutes out requirements. The correct answer is b.
Material Requirements Planning (MRP) is a system used in manufacturing and production management to effectively plan and manage the materials needed for production. It helps ensure that materials are available in the right quantities, at the right time, and in the right place.
In the context of the question, the blank should be filled with a term that relates to the process of substituting or replacing requirements. Among the options provided, "resource" is the most appropriate choice.
MRP systems allow for the substitution or replacement of materials based on availability or other factors. For example, if a required material is not available, the MRP system can suggest or substitute an alternative material that can fulfill the same function. This helps maintain the production process without causing delays or interruptions.
The other options provided, such as recycle, return, and reuse, do not directly relate to the substitution or replacement of requirements within the context of material requirements planning.

Sulfuric acid is produced by first burning sulfur to produce sulfur trioxide gas
2S(s) + 3O2(g) → 2SO3(g)
then dissolving the sulfur trioxide gas in water
SO3(g) + H2O(l) → H2SO4(l)
Calculate the mass of sulfuric acid produced if 1.25 g of sulfur is reacted as indicated in the above equations.
Answers
Answer:
3.82 g.
Explanation:
To calculate the mass of sulfuric acid produced from 1.25 g of sulfur, we'll have to balance the chemical equations and use stoichiometry.
Starting with the first reaction:
2S(s) + 3O2(g) → 2SO3(g)
Since 1.25 g of sulfur is reacted, the number of moles of sulfur can be calculated as:
moles = mass / molar mass = 1.25 g / 32 g/mol = 0.03906 mol
Next, using the mole ratio from the balanced chemical equation, we can find the number of moles of sulfur trioxide produced:
2 moles of sulfur produce 2 moles of sulfur trioxide, so:
moles of SO3 = moles of S x (moles of SO3 / moles of S) = 0.03906 mol x (2 mol / 2 mol) = 0.03906 mol
Finally, we move on to the second reaction, the dissolution of sulfur trioxide in water:
SO3(g) + H2O(l) → H2SO4(l)
Using the mole ratio from this balanced equation, we can find the number of moles of sulfuric acid produced:
1 mole of sulfur trioxide reacts with 1 mole of water to produce 1 mole of sulfuric acid, so:
moles of H2SO4 = moles of SO3 x (moles of H2SO4 / moles of SO3) = 0.03906 mol x (1 mol / 1 mol) = 0.03906 mol
The mass of sulfuric acid produced can be calculated using the moles and the molar mass of sulfuric acid:
mass = moles x molar mass = 0.03906 mol x 98 g/mol = 3.82 g
Therefore, if 1.25 g of sulfur is reacted, the mass of sulfuric acid produced is approximately 3.82 g.

There are 3 O's on left and only 2 on right so put 2 before NO:
H2S + HNO3 ----> 2NO + H2O + S
Now we have 2 N's on left so put 2 before HNO3:
H2S + 2HNO3 -----> 2NO + H2O + S
4 H's on the left so
H2S + 2HNO3 -----> 2NO + 2H2O + S
That makes 6 O's on left so we write
H2S + 2HNO3 ----> 2NO + 4H2O + S
Now there 8 H's on the right but only 4 on the right so we adjust H2S and S:
3H2S + 2HNO3 -----> 2NO + 4H2O + 3S
Now it balances!

Would you use a water pipe that consists of the two metals? Justify your answer!
Answers
Answer:
No, i will not use a water pipe consisting of the two metals
Explanation:
Looking at the reduction potential of the both metals, it is clear that an electrochemical cell is set up with iron as the anode and copper as the cathode.
This will make the iron to quickly corrode and eventually destroy the water pipe. It is better to have a set up in which another metal that is higher than iron in the electrochemical series is combined with it.
A slightly edited Exercise 6 of Chapter 4 (Page 90) states:
(a) Calculate the energy needed to bring a cup of water (about 250 g) from 10°C to the boiling point (100°C for water). Then, find the time it takes to heat this water (c) in a 1-kg aluminum pan sitting on a 1,500-W electric stove burner that transfers 75% of its energy output to the water and the pan. Assume the pan, too, starts at 10°C and has to be heated to water’s boiling point.
Solution:
(a) To heat just the water requires energy Qw=mwcwΔT (Equation 4.3), where ΔT=100∘C−10∘C=90∘C:
Qw=0.25kg(4184Jkg∘C)90∘C=94,140J
(c) On the stove, we also have to heat the pan. Aluminum’s specific heat is ca=900Jkg∘C , from table 4.3, (because this is lower than cw, it is easier to heat aluminum than water).
To heat just the aluminum pan requires energy, Qa=macaΔT=1kg(900Jkg∘C)90∘C.
The total energy to heat the pan of water on the stove is increased because of the finite efficiency:
Qtotal=Qw+Qaes=94,140J+81,000J0.75=233,520J
The time it takes to heat the water depends on the stove’s power: power = energy per time, so
t=energypower=QtotalPs=233,520J1,500Js=155.68or156sonthestove
Question:
Find the time, in seconds, it takes to heat this water in a 1-kg steel pan sitting on a 1,500-W electric stove burner that transfers 75% of its energy output to the water and the pan.

Answers
The time it takes to heat this water in a 1-kg steel pan sitting on a 1,500-W electric stove burner that transfers 75% of its energy output to the water and the pan is 90 seconds (rounded to the nearest whole second).
We need to calculate the time taken to heat the water in a 1-kg steel pan sitting on a 1,500-W electric stove burner that transfers 75% of its energy output to the water and the pan. The given information are as follows:
Specific heat of water, cw = 4184 J/kg °C
Specific heat of steel, cs = 450 J/kg °C
Energy supplied by the electric stove burner, P = 1,500 W (75% of which is transferred to the water and the pan)
Mass of water, mw = 250 g = 0.25 kg
Mass of steel pan, ms = 1 kg
Initial temperature of water and steel pan, T1 = 10 °C
Final temperature of water and steel pan (boiling point of water), T2 = 100 °C
Heat absorbed by the steel pan = Qs = ms × cs × (T2 - T1)Heat absorbed by the water = Qw = mw × cw × (T2 - T1)
Total heat absorbed by the water and the pan = Q = Qw + Qs = (0.25 × 4184 × 90) + (1 × 450 × 90) J= 94,140 + 40,500 J= 1,34,640 J
Time taken to heat the water and the pan = t = Q/P= 1,34,640 / 1,500 s= 89.76 or 90 s
Therefore, the time it takes to heat this water in a 1-kg steel pan sitting on a 1,500-W electric stove burner that transfers 75% of its energy output to the water and the pan is 90 seconds (rounded to the nearest whole second).

The peanut has more energy than the chip.
The experiment was flawed because more than one variable was being tested.
The peanut and the chip have the same amount of energy.
Answers
Since the water increased by 7 degrees for the peanut and 3 degrees for the chip, the conclusion would be that the peanut has more energy than the chip.
CalorimetryCalorimetry is the science of measuring the quantity of energy, usually in the form of heat, that is released during a reaction.
In this case, the energy released by the peanut and the chip were measured using calorimetry. The energy released was captured by the water and helps raise the temperature of the water.
The more energy released by the substances, the more the temperature of the water is raised.
Thus, since the peanut raised the temperature of the water by 7 degrees while the chip was only able to raise it by just 3 degrees, one can effectively conclude that the peanut has more energy than the chip.

Due to its lower polarity and fewer interactions with the adsorbent, ferrocene was the first substance to elute from the column.
Define column chromatography
When doing microscale research, column chromatography is one of the most helpful techniques for the separation and purification of both solids and liquids. The polarity and binding strengths that the constituents of a mixture have for column absorbents are utilised by chromatography. Adsorbents are stationary phase components with a large surface area that bind solute molecules.
Due to its lower polarity and preference for the less polar solvent, ferrocene went along the column more quickly. Based on the same theories, it travelled farther on the TLC plate because it is less polar and has a lesser affinity for the silica gel.

About Acid rainAcid rain is defined as all kinds of rain with a pH below 5.6. Rain is naturally acidic (pH slightly below 6) because carbon dioxide (CO2) in the air which dissolves with rainwater has the form a weak acid . This type of acid in rain is very useful because it helps dissolve the minerals in the soil which are needed by plants and animals.
Acid rain is caused by Sulfur which is an impurity in fossil fuels as well as nitrogen in the air which reacts with oxygen to form sulfur dioxide and nitrogen oxides. These substances diffuse into the atmosphere and react with water to form sulfuric acid and nitric acid which are easily soluble so that they fall with the rainwater. This acidic rainwater will increase the acidity of the soil and surface water which will prove harmful to fish and plant life. Efforts to overcome this are currently being intensively implemented.
