(b) O₂(g) is introduced into the same vessel containing the hydrocarbon. After the addition of
the O₂(g), the total pressure of the gas mixture in the vessel is 1.40 atm at 127°C. Calculate
the partial pressure of O₂(g) in the vessel. A = Peotal x roles oz
Zotal coles

Answers

Answer:

look below

Explanation:

It is not clear from the information provided what the initial pressure of the hydrocarbon was or the moles of each gas present in the vessel. In order to solve for the partial pressure of O₂(g), we need to know the total pressure of the gas mixture, the temperature, and the moles of each gas present.

Assuming that the temperature and total pressure of the gas mixture are as stated, we can use the ideal gas law to solve for the partial pressure of O₂(g). The ideal gas law is given by the equation:

PV = nRT

where P is the pressure of the gas, V is the volume of the gas, n is the number of moles of the gas, R is the ideal gas constant, and T is the temperature in Kelvin.

If we let X be the partial pressure of O₂(g), Y be the partial pressure of the hydrocarbon, and n1 and n2 be the number of moles of O₂(g) and the hydrocarbon, respectively, we can set up the following system of equations:

X + Y = 1.4 atm

n1R(127+273) = XV

n2R*(127+273) = Y*V

We can solve this system of equations to find the partial pressure of O₂(g). However, we need to know the values of n1, n2, and V in order to do so. Without this information, it is not possible to calculate the partial pressure of O₂(g).

a solution of cacl2 in water forms a mixture that is 35.5% calcium chloride by mass. if the total mass of the mixture is 497.5 g, what masses of cacl2 and water were used?

Answers

a solution of cacl2 in water forms a mixture that is 35.5% calcium chloride by mass. if the total mass of the mixture is 497.5 g, masses of cacl2 and water are 174g and 323.8 g H2O

Given that the solution is 35.0% CaCl2 by mass, we simply multiply the total mass by 0.350 (35%) to obtain the mass of CaCl2. 0.350 x 497.8 g = 174.23 g = 174 g CaCl2. To find the mass of H2O, simply subtract the mass of CaCl2 from the total mass as follows: mass H2O = 497.8 g - 174 g = 323.8 g H2O.

Polar protic solvents:

Stabilize the carbocation intermediate. A polar protic solvent, such as methanol, has a permanent dipole which means that the delta negative (partial negative charge) on the molecule will have dipole-dipole interactions with the carbocation, stabilizing it.
Reduce the reactivity of the nucleophile. The polar protic solvent can interact electrostatically with the nucleophile thereby stabilizing it. This reduces the reactivity of the nucleophile which favors an Sn1 reaction over an Sn2 reaction.

Answers

If 60.0 of aluminum oxide with 30.0 g of carbon, then the percent yield of the given reaction is 70.9%

Now, we have reaction from the above information is

Al₂O₃ + 3C=3CO + 2Al

Mass of aluminum oxide = 60.0 g

Molecular mass of aluminum oxide=2 × mass of aluminum + 3× mass of oxygen is

2×26.12 +3 × 16.43=52.24+49.29=101.53g

Moles of aluminum oxide =60/101.53=0.588mol.

Mass of carbon = 22.5 g

We know that atomic mass of carbon is 12.01g.

Moles of carbon= 22.5/12.01=2.50g/mol

From the reaction, we get that 1 mole of aluminum oxide reacts with 3 moles of carbon, then 0.588 moles of aluminum oxide will react with:

=3 × 0.588mol=1.764 mol of carbon

Now,we got that 0.588 moles of aluminum oxide react with 1.764 moles of carbon. According to reaction, 1 mole of aluminum oxide gives 2 moles of aluminum, then 0.588 moles of aluminum oxide will give:

2× 0.588mol=1.176mol of aluminum

Mass of 1.176 moles of aluminum =1.176×26.98g/mol=31.72g/mol

Now, we got that the theoretical yield of the reaction = 31.73 g and The experimental yield of the reaction = 22.5 g

So, the percent yield of the reaction=experimental yield/theoretical yield

=>percentage yield = (22.5/31.73) × 100

=>percentage yield =70.91%=70.9%.

Calculate the speed of sound in air at 0° C that is composed of 60% nitrogen, 20% oxygen and 20% carbon. The molar mass of each element is 28 g/mol, 32 g/mol and 12 g/mol respectively.

Answers

Answer:

the speed of sound in air at 0° C that is composed of 60% nitrogen, 20% oxygen, and 20% carbon is 331.5 m/s.

Explanation:

The speed of sound in a gas is determined by the temperature and the molecular weight of the gas. To calculate the speed of sound in air, we need to first determine the average molecular weight of the air. The average molecular weight of a gas mixture is given by:

M = (f1 * M1 + f2 * M2 + ... + fn * Mn) / (f1 + f2 + ... + fn)

Where M is the average molecular weight, fi is the mole fraction of each component in the gas mixture (the fraction of total moles of that component), and Mi is the molecular weight of each component.

In this case, we have:

M = (0.6 * 28 g/mol + 0.2 * 32 g/mol + 0.2 * 12 g/mol) / (0.6 + 0.2 + 0.2)

= 29.6 g/mol

The speed of sound in air at 0° C is given by:

c = 331.5 * sqrt(1 + (T / 273.15))

Where c is the speed of sound in m/s, T is the temperature in °C, and 273.15 is the temperature at which the speed of sound is 331.5 m/s.

Substituting the values and solving for c, we get:

c = 331.5 * sqrt(1 + (0 / 273.15))

= 331.5 m/s

Therefore, the speed of sound in air at 0° C that is composed of 60% nitrogen, 20% oxygen, and 20% carbon is 331.5 m/s.

Chemical bonding between atoms creates compounds, which have distinctive structures made up of two or more atoms. Chemical formulas can be used to describe a compound's fundamental makeup. A covalent bond is the attraction between two atoms that share a pair of valence electrons. Both atoms' nuclei are attracted to the shared electrons. A molecule containing two or more atoms is created as a result of this. Molecules are created when similar or unrelated atoms come together. Thus, a hydrogen molecule is created when two hydrogen atoms come together. Almost all atoms can interact with other atoms.

glucose, c6h12o6 c 6 h 12 o 6 , is a sugar found in fruits and honey. what is the molar mass of fructose?

Answers

glucose, c6h12o6 c 6 h 12 o 6 , is a sugar found in fruits and honey.. C6H12O6 is the molecular formula for it. It is commonly known as white power. fructose has a molecular mass of 180.156 g/mol.

Fructose is absorbed inside the liver to produce primarily glucose (50%), in addition to lesser amounts of glycogen (>17%), produce milk (25%), and fatty acids. Glucose is decided to carry by the blood system to all muscles and organs where it is converted into energy. Lactate and fatty acids are both sources of energy for the body. A chemical compound's molarity is defined as the mass of a sample of that chemical divided by the amount of substance in that sample, which is the quantity of moles in that specimen, measured in moles. The molar mass of a material is a high volume characteristic, not a single - molecule property.
