Answer: 4.88 g/mol. and helium

Explanation:

To find the molar mass of the gas, we can use the ideal gas law equation which is PV=nRT where:

P = pressure = 2.000 atm

V = volume = 50.00 L

n = number of moles

R = gas constant = 0.08206 L·atm/K·mol

T = temperature = 273.15 K

First, we need to find the number of moles of the gas:

PV = nRT

n = PV/RT

n = (2.000 atm)(50.00 L)/(0.08206 L·atm/K·mol)(273.15 K)

n = 1.844 mol

Now, we can find the molar mass of the gas by dividing its mass by the number of moles:

molar mass = mass/number of moles

mass = 9.00 g

molar mass = 9.00 g/1.844 mol

molar mass = 4.88 g/mol

Therefore, the molar mass of the gas is 4.88 g/mol.

To determine what gas this is, we can compare the molar mass of the gas to the molar masses of known gases. The molar mass of 4.88 g/mol is closest to that of helium (4.00 g/mol). Therefore, this gas is most likely helium.

In the pair (e) CH3NH2 or CH3F, the dominant intermolecular forces in CH3NH2 are hydrogen bonds, while CH3F has London dispersion forces. Therefore, CH3NH2 has the higher boiling point.

In the pair (f) CH3OH or CH3CH2OH, the dominant intermolecular forces in CH3OH and CH3CH2OH are hydrogen bonds. Therefore, CH3OH has the higher boiling point.

In the pair (g) CH3CH2CH2CH2CH2CH3 or 2,2-dimethylbutane, the dominant intermolecular forces in both molecules are London dispersion forces. Therefore, CH3CH2CH2CH2CH2CH3 has the higher boiling point.

Answer:true

Explanation:

The pressure of the gas using the ideal gas equation is 14.93 atm.

The pressure of the gas using the van der Waals equation is 3.82 atm.

The pressure of the gas using the ideal gas equation is calculated as follows;

PV = nRT

where;

P = nRT/V

P = (3.9 x 0.08205 x 294)/(6.3)

P = 14.93 atm

P = (RT/Vm - b) - a/Vm²

P = (0.08205 x 294) / (6.3 - 0.03183) - (1.36)/(6.3²)

P = 3.85 - 0.034

Explanation:

We frequently observe kids playing with polythene bags filled with water that have little holes drilled into them at various locations so they can sprinkle water on other kids. Through this experiment, we can say that pressure acts in all directions in liquids.

Since both liquids and gases may flow, they are both referred to as fluids. Fluids under rest pressure behave uniformly in all directions.

Weather forecasts can be made using barometers. They track the evolution of atmospheric pressure throughout time.

On weather forecast maps, pressure variations appear as an isobar pattern. Predictions are made using these changes in pressure, and they are fairly accurate when combined with wind observations.

As you go away from a liquid's surface, pressure rises. for instance: A bucket has three holes that are all the same size. Since there is more pressure at the bucket's bottom, the water spills out more forcefully. Dams are thicker at the bottom for this reason.

Answer:

approximately 137.3 grams of P2O3 will form if one uses 78 grams of oxygen.

Explanation:

Diphosphorus trioxide, P2O3, is formed from the reaction of phosphorus with oxygen:

P4 + 5O2 -> 2P2O3

To determine how many grams of P2O3 will form from 78 grams of oxygen, we need to know how much phosphorus is also involved in the reaction. If we assume that there is enough phosphorus present, then we can calculate the amount of P2O3 that will be produced.

The balanced equation tells us that for every 2 moles of P2O3 that are produced, 4 moles of P4 and 5 moles of O2 are consumed. From the number of moles of O2, we can calculate the number of moles of P2O3 produced using the ratio from the balanced equation:

78 g O2 / (32 g/mol O2) = 2.43 mol O2

2.43 mol O2 * (2 mol P2O3 / 5 mol O2) = 0.972 mol P2O3

Finally, we can convert the number of moles of P2O3 to grams:

0.972 mol P2O3 * (141.94 g/mol P2O3) = 137.3 g P2O3

So, approximately 137.3 grams of P2O3 will form if one uses 78 grams of oxygen.

Answer:

Atomic mass is calculated by adding protons and neutrons.

Explanation:

Atomic mass is the sum of protons and neutrons in an atomic nucleus. For example, the element Oxygen has 8 protons (derived from the atomic number) and 8 neutrons (derived from subtracting the amount of protons from the atomic mass).

We can craft an equation to show the relationship between these variables.

M - N = P, where M = Mass, N = Neutrons, and P = Protons

This equation can be rearranged to show the relationship between the neutrons and protons leading to the atomic mass. Simply add N to both sides of the equation.

M = N + P

This shows that atomic mass is equivalent to the sum of protons and neutrons in an atom's nucleus.

Answer:

3.32 L

Explanation:

Step 1: Write the balanced equation

TiCl₄(l) + 2 H₂O(g) → TiO₂(s) + 4 HCl(g)

Step 2: Calculate the moles corresponding to 14.0 g of TiCl₄

The molar mass of TiCl₄ is 189.68 g/mol.

14.0 g × 1 mol/189.68 g = 0.0738 mol

Step 3: Calculate the moles of H₂O needed to react with 0.0738 moles of TiCl₄

The molar ratio of TiCl₄ to H₂O is 1:2. The moles of H₂O needed are 2/1 × 0.0738 mol = 0.148 mol

Step 4: Calculate the volume corresponding to 0.148 moles of H₂O(g)

At standard temperature and pressure, 1 mole of H₂O(g) has a volume of 22.4 L.

0.148 mol × 22.4 L/1 mol = 3.32 L

pH of the Sr(OH)₂ solution : 12.6

pH is the degree of acidity of a solution that depends on the concentration of H⁺ ions. The greater the value the more acidic the solution and the smaller the pH.  

pH = - log [H⁺]  

Sr (OH) ₂ solution is a base with valence 2, so we determine the pOH from the OH ion concentration - which is expressed by pOH = - log [OH -]. After that we determine the pH value from the relationship:

[H⁺] [OH⁻] = Kw=10⁻¹⁴

pH + pOH = 14

Sr(OH)₂⇒Sr²⁺+2OH⁻

From equation [Sr(OH)₂] : [OH⁻]=1 : 2, so [OH⁻]=

\(\tt [OH^-]=2\times 2.10^{-2}=4.10^{-2}~M\)

\(\tt pOH=-log[OH^-]\\\\pOH=-log~4.10^{-2}\\\\pOH=2-log~4\rightarrow 1.398 \\\\pH+pOH=14\\\\pH=14-1.398\\\\pH=12.6\)

pH is the measurement of the concentration of hydrogen or hydronium ion in an aqueous solution. The pH of strontium hydroxide is 12.6.

The pH is the potential of hydrogen or the negative log of its concentration.

First, calculate the pOH of strontium hydroxide by:

\(\begin{aligned} \rm pOH &= \rm - log [OH ^{-}]\\\\&= \rm -log [4\times10^{-2}]\\\\&= 1.398\end{aligned}\)

Now, calculate pH from pOH as:

\(\begin{aligned}\rm pH &= 14 - \rm pOH\\\\&= 14 - 1.398\\\\&= 12.6\end{aligned}\)

Therefore, 12.6 is the pH of strontium hydroxide.

Steel is produced from pig iron through a process known as steelmaking or iron and steel production.

The pig iron obtained from the blast furnace contains high amounts of carbon, impurities, and other elements. To convert pig iron into steel, the carbon content needs to be reduced to desired levels, and impurities must be removed.One common method of steelmaking is the basic oxygen process (BOP). In this process, pig iron is placed in a vessel called a converter, where oxygen is blown through the molten metal. The oxygen reacts with the carbon and impurities, causing them to oxidize and form gases that are released. Alloying elements and desired additives can be added at this stage to achieve specific steel properties. Another method is the electric arc furnace (EAF), where an electric arc is used to heat and melt the pig iron, allowing impurities to be oxidized and removed.The advantages of using steel are numerous. Steel is strong, durable, and versatile, making it suitable for a wide range of applications. It has high tensile strength, which means it can withstand heavy loads and pressures. Steel is also resistant to corrosion, making it ideal for construction, infrastructure, and transportation projects. It is a recyclable material, contributing to sustainability and reducing environmental impact. Additionally, steel can be fabricated into various shapes and sizes, allowing for customization and flexibility in design.References:
