Answers
The answer is A Height and Mass
Gravitational potential energy depends on the strength of gravity; A. height and mass of the object.
Gravitational potential energy (G.P.E) can be defined as the energy possessed by a physical object or body due to its position (height) above planet Earth.
Hence, gravitational potential energy (G.P.E) is highly dependent on mass, height of an object or body and the acceleration due to gravity.
Mathematically, gravitational potential energy (G.P.E) is given by the formula;
\(GPE = mgh\)
Where:
G.P.E is the gravitational potential energy. m is the mass of an object. g is the acceleration due to gravity. h is the height of an object.In conclusion, the three (3) main factors that gravitational potential energy (G.P.E) depends on are:
I. Strength of gravity.
II. Height.
III. Mass.

Answers
When a catalyst is added to a reaction mixture, it provides a new pathway or mechanism for the reaction. This means that the catalyst creates an alternative route for the reaction to occur, which is typically a lower energy pathway than the original reaction mechanism.
By providing this new pathway, the catalyst reduces the activation energy required for the reaction to take place, making it easier for reactant molecules to participate in the reaction.
It is important to note that while a catalyst does not provide reactant molecules with more energy, it does increase the rate of collisions between reactant molecules. This is because the catalyst alters the structure of the reactants, making it more likely for them to collide in a way that promotes the desired reaction.
While a catalyst does not slow down the rate of the back reaction, it can often shift the equilibrium of the reaction in favor of the desired product. This is because the catalyst increases the rate of the forward reaction, making it more likely that products will be formed before they have a chance to react and form reactants again.
In summary, the addition of a catalyst to a reaction mixture provides a new pathway or mechanism for the reaction, increases the rate of collisions between reactant molecules, and can shift the equilibrium of the reaction in favor of the desired product.

B) A company president would like to offer a 4.00 L cylinder containing 500 g of chlorine in the new catalog. The cylinders you have on hand have a rupture pressure of 40 atm. Use both the ideal gas law and the van der Waals equation to calculate the pressure in a cylinder at 25°C. Given a = 6.58 L2 atm mol-2 and b = 0.056 L mol-2, Cl =35.5. (5 marks)
Answers
Answer:
43.1atm is the pressure using gas law and 27.2atm using Van der Waals Law.
Explanation:
Ideal gas law is:
PV = nRT
Where P is pressure in atm
V is volume = 4.00L
n are moles of the gas (For chlorine Molar Mass: 70.90g/mol):
500g * (1mol / 70.90g) = 7.052 moles
R is gas constant = 0.082atmL/molK
T is absolute temperature = 25°C + 273 = 298K
To solve the pressure, P:
P = nRT/V
P = 7.052mol*0.082atmL/molK*298K / 4.00L
P = 43.1atm is the pressure using gas law.
Van der Waals equation is:
\(P + a(\frac{n}{V})^2 * (V-nb) = nRT\)
Where a is 6.58L²atm*mol⁻²
b = 0.056Lmol⁻²
Solving for pressure:
\(P + a(\frac{n}{V})^2 = \frac{nRT}{(V-nb)}\)
\(P = \frac{nRT}{(V-nb)}-a(\frac{n}{V})^2\)
\(P = \frac{7.052mol*0.082atmL/molK*298K}{(4.00L-7.052mol*0.056L*mol)}-6.58L^2mol^{-2}(\frac{7.052mol}{4.00L})^2\)
P = 172.323 / 3.6051 - 20.4866
P = 27.2atm using Van der Waals Law
N2(g) + 3H2 (g)→2NH3(g) The reaction rate is measured as 0.032 M NH3/s. Determine the rate of disappearance of N2 and the rate of disappearance H2. Explain how you arrived at your answers.
Answers
The rate at which N\(_{2}\) disappears is 0.016 M/s, while the rate at which H\(_{2}\) disappears is 0.0213 M/s.
In the balanced chemical equation N\(_{2}\)(g) + 3 H\(_{2}\) (g) → 2NH\(_{3}\)(g), the stoichiometric coefficients represent the mole ratios between the reactants and products.
Since the reaction rate is given for NH\(_{3}\), we can determine the rates of disappearance of N\(_{2}\) and H\(_{2}\) by comparing their stoichiometric ratios in the reaction.
The stoichiometric ratio between N\(_{2}\) and NH\(_{3}\) is 1:2, meaning for every mole of N\(_{2}\) consumed, 2 moles of NH\(_{3}\) are produced. Therefore, the rate of disappearance of N\(_{2}\) is half of the rate of formation of NH\(_{3}\).
Similarly, the stoichiometric ratio between H\(_{2}\) and NH\(_{3}\) is 3:2. This means that for every 3 moles of H\(_{2}\) consumed, 2 moles of NH\(_{3}\) are produced. Therefore, the rate of disappearance of H\(_{2}\) is (2/3) times the rate of formation of NH\(_{3}\).
Given the rate of formation of NH\(_{3}\) as 0.032 M/s, the rate of disappearance of N\(_{2}\) would be 0.016 M/s (0.032 M/s ÷ 2), and the rate of disappearance of H\(_{2}\) would be approximately 0.0213 M/s (0.032 M/s × 2/3).
Therefore, the rate of disappearance of N\(_{2}\) is 0.016 M/s, and the rate of disappearance of H\(_{2}\) is 0.0213 M/s.

is the standard free energy of hydrolysis of phosphoarginine more similar to that of glucose 6‑phosphate or of atp? why?
Answers
The standard free energy of hydrolysis of phosphoarginine is more similar to that of ATP (adenosine triphosphate) rather than glucose 6-phosphate. This is because both phosphoarginine and ATP are high-energy phosphate compounds involved in energy transfer and metabolism.
Phosphoarginine is a phosphorylated compound found in certain organisms, particularly in tissues with high energy demands like muscle tissue. It serves as a reservoir for high-energy phosphate bonds, which can be rapidly hydrolyzed to release energy during muscle contraction.
Similarly, ATP is a universal energy currency in cells and is involved in various energy-requiring processes. It is hydrolyzed to ADP (adenosine diphosphate) and inorganic phosphate, releasing energy that can be utilized by cells.
On the other hand, glucose 6-phosphate is an intermediate in glucose metabolism and is not directly involved in energy transfer processes like phosphoarginine and ATP. While it does have a phosphorylated group, its role is primarily in carbohydrate metabolism rather than energy transfer.
Therefore, the standard free energy of hydrolysis of phosphoarginine is more similar to that of ATP due to their shared involvement in energy transfer and metabolism.

Examine the given Beer's law standard curve for an unknown dye measured in a 1. 0 cm cuvette. Y = 15200x-0. 18.
What is the molar absorptivity (in M–1cm–1) of the unknown dye at 542 nm?
Answers
The Beer's Law equation is A = εlc, where A is the absorbance, ε is the molar absorptivity, l is the path length (1.0 cm in this case), and c is the concentration.
Rearranging the equation, we can solve for ε: ε = A / (lc) = A / (l * c).
Since the equation given is Y = 15200x - 0.18, where x is the concentration,
we can use it to find the absorbance (A) at a given concentration.
For a concentration of x = 0.005 M, the absorbance (A) can be found by substituting the values into the equation: Y = 15200x - 0.18,
Y = 15200 * 0.005 - 0.18
Y= 0.76.
Therefore, the molar absorptivity (ε) at a wavelength of 542 nm for a concentration of 0.005 M can be calculated as:
ε = A / (lc)
Substitute the value in above equation we get,
= 0.76 / (1.0 * 0.005)
= 152 M^-1cm^-1.

Barium metal was quantitatively precipitated from a 1. 52 g sample of bacl2∙2h2o. The mass of the barium that was collected was 0. 844 g. Calculate the experimental mass percent of barium in the sample.
Answers
To calculate the experimental mass percent of barium in the sample, we need to use the following formula:
Experimental Mass Percent = (Mass of Barium / Mass of Sample) x 100
Given that the mass of the barium collected was 0.844 g and the mass of the sample was 1.52 g, we can substitute these values into the formula to calculate the experimental mass percent:
Experimental Mass Percent = (0.844 g / 1.52 g) x 100
Simplifying the equation:
Experimental Mass Percent = 0.555 x 100
Calculating the value:
Experimental Mass Percent = 55.5%
So, the experimental mass percent of barium in the sample is 55.5%. The experimental mass percent of barium in the sample is 55.5%. To calculate the experimental mass percent, we divided the mass of barium collected by the mass of the sample and multiplied the result by 100. This gives us the proportion of barium in the sample, expressed as a percentage. To calculate the experimental mass percent of barium in the sample, we used the formula (Mass of Barium / Mass of Sample) x 100. Given that the mass of barium collected was 0.844 g and the mass of the sample was 1.52 g, we substituted these values into the formula to calculate the experimental mass percent. By dividing 0.844 g by 1.52 g, we obtained the proportion of barium in the sample. Multiplying the result by 100, we converted this proportion into a percentage. The final result, 55.5%, represents the experimental mass percent of barium in the sample. This calculation allows us to quantify the amount of barium present in relation to the total sample mass.

iii. Self-cleansing and scouring velocity in sewers iv. Type 1 and Type 2 settling in water/wastewater treatment v. Chloramines and Disinfection by-products
Answers
Temporary and permanent hardness of water Temporary hardness of water is caused by the presence of bicarbonate, carbonate, and sulfate ions, while permanent hardness is caused by the presence of chlorides, sulfates, and nitrates.
Carbonate and bicarbonate hardness can be removed using a process called boiling. Permanent hardness, on the other hand, can be removed using a process called ion exchange.ii. Organic, ortho, and polyphosphorus in wastewaterOrganic phosphorus is present in wastewater in the form of organic molecules like DNA, RNA, and phospholipids. Orthophosphate is the most common form of phosphorus found in wastewater. Polyphosphates, which are a chain of orthophosphate molecules, can also be found in wastewater.iii. Self-cleansing and scouring velocity in sewersSelf-cleansing velocity is the minimum velocity of wastewater flow required to prevent the deposition of solids in the sewer. Scouring velocity, on the other hand, is the minimum velocity required to remove previously deposited solids. Scouring velocity is higher than self-cleansing velocity.
Type 1 and Type 2 settling in water/wastewater treatment Type 1 settling occurs when particles of different sizes and densities settle separately, forming distinct layers. In type 2 settling, particles of different sizes and densities settle together in a mixed floc. Type 1 settling is more effective at removing larger particles, while type 2 settling is better at removing smaller particles.v. Chloramines and disinfection by-products (DBPs)Chloramines are a combination of chlorine and ammonia that are used as a disinfectant in water treatment. Disinfection by-products (DBPs) are formed when chlorine reacts with organic matter in the water.
