Answer:

219600 Pa (or 2.196 bar, or 31.9 psi).

Explanation:

weight of water:

volume of water = 2m x 5m x 8m = 80 cubic meters

weight of water = volume of water x density of water x gravitational acceleration

density of water is 1000 kg/m^3 and the gravitational acceleration is 9.81 m/s^2.

weight of water = 80 x 1000 x 9.81 = 784800 N

weight of the tank

volume of tank = 2m x 5m x 8m = 80 cubic meters

weight of tank = volume of tank x density of tank x gravitational acceleration

relative density of the tank material is 1.8, which means its density is 1.8 times that of water, or 1800 kg/m^3.

weight of tank = 80 x 1800 x 9.81 = 1411200 N

The total weight acting on the bottom of the tank is the sum of the weight of the water and the weight of the tank:

Total weight = weight of water + weight of tank = 2196000 N

The max pressure at the bottom of the tank is the total weight divided by the area of the bottom of the tank:

max pressure = total weight / area of bottom of tank

the area of the bottom of the tank is 2m x 5m = 10 square meters.

Max pressure = 2196000 N / 10 m^2 = 219600 Pa

Therefore, your answer is 219600 Pa (or 2.196 bar, or 31.9 psi)

Soil is a mixture of organic and inorganic materials that forms the uppermost layer of the Earth's crust. It is a complex, three-dimensional matrix of mineral particles, organic matter, water, air, and living organisms. Soil provides critical habitat for various microorganisms, insects, plants, and animals, making it a key component of terrestrial ecosystems.

Soil is formed through weathering, which breaks down rocks and other materials into smaller particles. Various factors, including temperature, moisture, wind, and the activities of living organisms, influence this process. Over time, layers of organic matter accumulate on the soil's surface, creating a rich environment for plant growth.

Soil has several important functions, including supporting plant growth, regulating water flow, and cycling nutrients. It also plays a key role in carbon sequestration, helping mitigate climate change's impacts by storing carbon in the form of organic matter.

In magnesium hydroxide, magnesium makes up 41.7% of the compound by mass, and oxygen makes up 55.1% of the compound by mass. The remaining percentage would be hydrogen.

What is Percentage Composition?

Percentage composition refers to the relative mass of each element in a chemical compound expressed as a percentage of the total molecular mass of the compound. In other words, it is the percentage by mass of each element present in a compound.

To determine the percent composition of magnesium hydroxide in a substance, we need to know the mass of magnesium hydroxide in the substance and the total mass of the substance.

Without knowing the substance in question, we cannot determine the mass of magnesium hydroxide. However, we can use the chemical formula of magnesium hydroxide (Mg(OH)2) to calculate the mass percent of magnesium and oxygen in the compound.

The molar mass of magnesium hydroxide is:

24.31 g/mol (for Mg) + 2(15.999 g/mol) (for 2 O) + 2(1.008 g/mol) (for 2 H) = 58.32 g/mol

The mass percent of magnesium in magnesium hydroxide is:

(24.31 g/mol / 58.32 g/mol) x 100% = 41.7%

(2 x 15.999 g/mol / 58.32 g/mol) x 100% = 55.1%

Therefore, in magnesium hydroxide, magnesium makes up 41.7% of the compound by mass, and oxygen makes up 55.1% of the compound by mass. The remaining percentage would be hydrogen.

The mass of aluminum that reacted to produce this quantity of hydrogen gas is 0.181 g.

Partial pressure is a term used in chemistry and physics to describe the pressure that a single gas component would exert if it occupied the same volume as a mixture of gases. In a mixture of gases, each gas exerts a pressure known as its partial pressure, which is proportional to the number of molecules of that gas in the mixture.

To calculate the partial pressure of hydrogen gas in the sample, we can use the following equation:

Partial pressure of hydrogen gas = Total pressure - Vapor pressure of water

Partial pressure of hydrogen gas = 129 kPa - 4.10 kPa = 124.90 kPa

Therefore, the partial pressure of hydrogen gas in the sample is 124.90 kPa.

To calculate the mass of aluminum that reacted to produce this quantity of hydrogen gas, we need to use the balanced chemical equation for the reaction and the ideal gas law. The balanced chemical equation for the reaction of aluminium with hydrochloric acid is as follows:

2Al + 6HCl = 2AlCl3 + 3H2

From the equation, we see that two moles of aluminum react to produce three moles of hydrogen gas. We can use the ideal gas law to calculate the number of moles of hydrogen gas in the sample:

PV = nRT

n = PV/RT

where P is the partial pressure of hydrogen gas, V is the volume of gas collected, R is the gas constant, and T is the temperature in kelvin.

First, we need to convert the temperature from Celsius to kelvin:

T = 29.4 + 273.15 = 302.55 K

Next, we can calculate the number of moles of hydrogen gas:

n = (124.90 kPa)(206.1 mL)/(8.31 L·kPa/mol·K)(302.55 K)

n = 0.0101 moles

Since two moles of aluminum react to produce three moles of hydrogen gas, the number of moles of aluminum that reacted is:

n(Al) = (2/3)n(H2) = (2/3)(0.0101 moles) = 0.00673 moles

Finally, we can use the molar mass of aluminum to calculate the mass of aluminum that reacted:

mass(Al) = n(Al) × molar mass(Al)

mass(Al) = 0.00673 moles × 26.98 g/mol = 0.181 g

The answer to this question depends on the reaction that is taking place.

Reaction is the process of responding to a stimulus. It is an instinctive response to an event, person, object, or situation. It can be conscious or unconscious, rational or irrational. Reactions can be physical (e.g. facial expressions, body language, etc.) or mental (e.g. thoughts, feelings, beliefs, attitudes, etc.). Reactions can vary from person to person, depending on the individual's beliefs and experiences. Reaction is often used to evaluate the success of a stimulus or to measure the intensity of a response.

If the reaction involves the combination of Hg and O2, then the amount of Hg produced will be the same as the amount of O2 produced, which in this case is 310.71 grams.

At the equivalence point, 0.505 g of phenol reacted with 0.123 M NaOH to form 0.0318 M phenolate ion and 0.0319 M sodium ion, with 0 M hydroxide ion and 0.0318 M H3O+.

The balanced equation for the titration reaction is:

C6H5OH(aq) + OH-(aq) → C6H5O-(aq) + H2O(ℓ)

From the equation, we can see that 1 mole of phenol reacts with 1 mole of hydroxide ion (OH-). To determine the moles of hydroxide ion required to reach the equivalence point, we can use the following equation:

moles of OH- = M × V

where M is the concentration of NaOH, and V is the volume of NaOH required to reach the equivalence point.

To find the volume of NaOH required to reach the equivalence point, we need to calculate the moles of phenol present in the solution. We can use the following equation to do this:

moles of C6H5OH = mass ÷ molar mass

where the molar mass of phenol is 94.11 g/mol.

moles of C6H5OH = 0.505 g ÷ 94.11 g/mol = 0.005368 mol

Since 1 mole of phenol reacts with 1 mole of hydroxide ion, the moles of hydroxide ion required to reach the equivalence point is also 0.005368 mol. Using the equation above, we can calculate the volume of NaOH required:

moles of OH- = M × V

0.005368 mol = 0.123 M × V

V = 0.0437 L = 43.7 mL

Therefore, the volume of NaOH required to reach the equivalence point is 43.7 mL.

At the equivalence point, all of the phenol has reacted with the hydroxide ion, and we have a solution containing only the phenolate ion (C6H5O-) and water. The moles of C6H5O- formed at the equivalence point is equal to the moles of hydroxide ion added:

moles of C6H5O- = moles of OH- added = 0.005368 mol

The volume of the solution at the equivalence point is 125 mL + 43.7 mL = 168.7 mL.

Now, we can use the initial volume and concentration of the phenol solution to calculate the concentration of the phenolate ion and other ions at the equivalence point. The initial concentration of the phenol solution is:

C6H5OH = 0.505 g ÷ (94.11 g/mol × 0.125 L) = 0.424 M

Since the moles of phenol and phenolate ion are equal at the equivalence point, the concentration of the phenolate ion is also 0.005368 mol ÷ 0.1687 L = 0.0318 M.

At the equivalence point, all of the hydroxide ions have reacted with the phenol to form the phenolate ion and water. Therefore, the concentration of hydroxide ion at the equivalence point is 0 M.

The balanced equation also tells us that for every phenolate ion formed, a hydronium ion (H3O+) is also formed. Therefore, the concentration of H3O+ at the equivalence point is equal to the concentration of the phenolate ion:

[H3O+] = 0.0318 M

Finally, to calculate the concentration of sodium ion (Na+) at the equivalence point, we need to consider the balanced equation. For every mole of phenol that reacts, a mole of sodium hydroxide is consumed, forming a mole of sodium phenolate. Therefore, the moles of sodium ion in the solution at the equivalence point is equal to the moles of sodium hydroxide added to reach the equivalence point:

moles of Na+ = moles of NaOH added = 0.123 M × 0.0437 L = 0.00537 mol

The volume of the solution at the equivalence point is 0.1687 L. Therefore, the concentration of sodium ion at the equivalence point is:

[Na+] = 0.00537 mol ÷ 0.1687 L = 0.0319 M

In summary, at the equivalence point of the titration of 0.505 g of phenol with 0.123 M sodium hydroxide solution, the volume of NaOH required is 43.7 mL, and the concentration of the phenolate ion is 0.0318 M, the concentration of hydroxide ion is 0 M, the concentration of H3O+ is 0.0318 M, and the concentration of sodium ion is 0.0319 M.
