a 2.0 l container of oxygen had a pressure of 3.2 atm. what volume would be necessary to decrease the pressure to 1.0 atm?
Answers
decrease the pressure of a 2.0 L container of oxygen from 3.2 atm to 1.0 atm, the volume of the container would need to be 6.4L
In order to decrease the pressure of a 2.0 L container of oxygen from 3.2 atm to 1.0 atm, the volume of the container would need to be increased. This can be calculated using Boyle's Law, which states that the pressure and volume of a gas are inversely proportional. Therefore, in order to reduce the pressure from 3.2 atm to 1.0 atm, the volume would need to be increased to 6.4 L. This can be found by solving the equation PV = nRT for V, with P1 being 3.2 atm, P2 being 1.0 atm, n being 1 mol, R being 0.0821, and T being 300 K. Solving this equation gives V2 = 6.4 L. Thus, the volume of the container would need to be increased to 6.4 L in order to decrease the pressure to 1.0 atm.

compute the repeat unit molecular weight of polypropylene. compute the number-average molecular weight for a polypropylene for which the degree of polymerization is 15,00
Answers
The number-average molecular weight of the polypropylene is approximately 63,120 g/mol.
The repeat unit molecular weight of polypropylene can be calculated by summing the atomic weights of all the atoms in the monomer unit. The monomer unit of polypropylene is:
CH3-CHCH2
The atomic weights of the atoms in this monomer unit are:
C = 12.01
H = 1.008
Adding these atomic weights gives:
12.01 + 3(1.008) + 2(12.01) + 1.008 = 42.08 g/mol
Therefore, the repeat unit molecular weight of polypropylene is approximately 42.08 g/mol.
The number-average molecular weight of a polymer is given by the formula:
Mn = (ΣNiMi) / ΣNi
where Ni is the number of polymer chains with molecular weight Mi.
For a polypropylene with a degree of polymerization of 1500, the number of polymer chains is:
N = 2^(n-1) = 2^(1500-1) = 1.76 x 10^450
Assuming a polydispersity index of 1.0, which means all polymer chains have the same molecular weight, the number-average molecular weight can be calculated as:
Mn = (N)(M) / N = M
where M is the molecular weight of a single polymer chain.
The molecular weight of a single polymer chain can be calculated by multiplying the repeat unit molecular weight by the degree of polymerization:
M = (repeat unit molecular weight) x (degree of polymerization)
M = 42.08 g/mol x 1500
M = 63,120 g/mol
Therefore, the number-average molecular weight of the polypropylene is approximately 63,120 g/mol.

the molar solubility of silver sulfate in a 0.144 m ammonium sulfate solution is
Answers
The molar solubility of silver sulfate in a 0.144 M ammonium sulfate solution is 0.00166 M.
To find the molar solubility of silver sulfate in a 0.144 m ammonium sulfate solution, we need to use the common ion effect. Ammonium sulfate is a salt that dissociates into ammonium cations and sulfate anions in solution. When we add silver sulfate to this solution, it will also dissociate into silver cations and sulfate anions. However, the sulfate anions from both salts will compete for the available ammonium cations in solution. This will cause the solubility of silver sulfate to decrease due to the reduction in the concentration of free sulfate ions.
To calculate the molar solubility of silver sulfate, we can use the Ksp expression for silver sulfate:
Ag2SO4(s) ⇌ 2Ag+(aq) + SO42-(aq)
Ksp = [Ag+]^2[SO42-]
The molar solubility of silver sulfate (x) in the presence of ammonium sulfate can be expressed as:
Ag2SO4(s) ⇌ 2Ag+(aq) + SO42-(aq)
Initial: 0 0 0
Change: -2x +2x +x
Equilibrium: -2x +2x x
The equilibrium expression for the dissociation of ammonium sulfate is:
(NH4)2SO4(s) ⇌ 2NH4+(aq) + SO42-(aq)
The initial concentration of sulfate ions in the solution is 0.144 M (from the ammonium sulfate), and we assume that all of it comes from the dissociation of ammonium sulfate. Therefore, the concentration of sulfate ions in the presence of silver sulfate is:
[SO42-] = 0.144 M + x
Substituting this into the Ksp expression and simplifying, we get:
Ksp = (2x)^2(0.144 M + x) = 4x^2(0.144 M + x)
Since the molar solubility of silver sulfate is very small compared to 0.144 M, we can make the assumption that x << 0.144 M. This means that we can neglect x when adding it to 0.144 M in the expression above, giving:
Ksp ≈ 0.576x^2
Now we can solve for x by substituting the given Ksp value (1.2 x 10^-5) and solving the quadratic equation:
1.2 x 10^-5 = 0.576x^2
x = 0.00166 M

a 0.259 mol sample of ch4 gas is contained in a 8.00 l flask at room temperature and pressure. what is the density of the gas, in grams/liter, under these conditions?
Answers
The density of sample CO₂ gas under the given conditions is calculated to be 2.99 g/L.
The density of a 0.259 mol sample of CH4 gas contained in an 8.00 l flask at room temperature and pressure can be calculated using the ideal gas law equation:
PV = nRT.
Where P is the pressure,
V is the volume,
n is the amount of gas (in moles),
R is the ideal gas constant and T is the temperature.
Plugging in the given values, we get:
\(PV = (0.259\ mol)(0.082057\ L.atm.K^{-1}.mol^{-1}) (273.15\ K)\)
\(P = (0.259\ mol)(0.082057 L.atm.K^{-1}.mol{-1}) (273.15\ K)/ (8.00\ L) = 0.959\ atm.\)
The density of the gas can be found by rearranging the ideal gas law equation to solve for density:
D = m/V.
Where D is the density, m is the mass of the gas and V is the volume.
Plugging in the given values, we get:
D = (0.259 mol)(16.04 g/mol)/ 8.00 L
= 2.99 g/L
Therefore, the density of the 0.259 mol sample of CH4 gas contained in an 8.00 l flask at room temperature and pressure is 2.99 g/L.

What volume of oxygen gas reacts if 56.1 grams of magnesium oxide are produced, according to the reaction below at STP? 2Mg(s) + O2(g) —> 2MgO(s)
Answers
Answer: 15.56 L of oxygen gas reacts to produce 56.1 grams of magnesium oxide at STP.
Explanation:
The given chemical equation represents the reaction between magnesium (Mg) and oxygen (O2) to form magnesium oxide (MgO) with a stoichiometric ratio of 2:1 between Mg and O2. This means that for every 2 moles of Mg that reacts, 1 mole of O2 is consumed.
The molar mass of MgO is 40.3 g/mol (24.3 g/mol for Mg + 16.0 g/mol for O). Therefore, the number of moles of MgO produced can be calculated as follows:
Number of moles of MgO = Mass of MgO / Molar mass of MgO
Number of moles of MgO = 56.1 g / 40.3 g/mol
Number of moles of MgO = 1.39 mol
Since the stoichiometric ratio of Mg to O2 is 2:1, we can calculate the number of moles of O2 consumed as follows:
Number of moles of O2 = (Number of moles of MgO) / 2
Number of moles of O2 = 1.39 mol / 2
Number of moles of O2 = 0.695 mol
At STP (standard temperature and pressure), one mole of any ideal gas occupies 22.4 L. Therefore, the volume of O2 consumed can be calculated as follows:
Volume of O2 consumed = Number of moles of O2 x 22.4 L/mol
Volume of O2 consumed = 0.695 mol x 22.4 L/mol
Volume of O2 consumed = 15.56 L
Therefore, 15.56 L of oxygen gas reacts to produce 56.1 grams of magnesium oxide at STP.

Study the chemical reaction how many product molecules are produced in this reaction
2H2 + O2 -> 2H2O
Answers
Two molecules of water (\(H_2O\)) are produced as the products of the reaction.
In the chemical reaction 2\(H_2\) + \(O_2\) -> 2(\(H_2O\)), two molecules of hydrogen and one molecule of oxygen react to form two molecules of water.
The balanced equation for this reaction is:
2\(H_2\) + \(O_2\) ----> 2(\(H_2O\))
The number of product molecules in this reaction is equal to the number of reactant molecules that are consumed in the reaction. In this case, there are two molecules of hydrogen \(H_2\) and one molecule of oxygen in the reactant list, so two molecules of hydrogen and one molecule of oxygen are consumed in the reaction.
Therefore, two molecules of water ((\(H_2O\))) are produced as the products of the reaction.

Answers
The electrons and hydrogens are carried from the Krebs cycle to the electron transport chain using nicotinamide adenine dinucleotide (NADH) and flavin adenine dinucleotide (FADH2) as electron carriers.
During cellular respiration, the Krebs cycle (also known as the citric acid cycle) is a critical metabolic pathway that occurs in the mitochondria of eukaryotic cells. In this cycle, electrons and hydrogens are produced through a series of chemical reactions, resulting in the generation of energy-rich molecules like NADH and FADH2. NADH and FADH2 act as electron carriers, which transport high-energy electrons from the Krebs cycle to the electron transport chain (ETC), the final stage of cellular respiration. NADH and FADH2 donate these electrons to the ETC, a series of protein complexes located in the inner mitochondrial membrane. As electrons pass through the ETC, their energy is used to pump protons across the membrane, creating a proton gradient. This gradient drives the synthesis of ATP, the primary energy currency of cells. In summary, NADH and FADH2 play crucial roles in cellular respiration by carrying electrons and hydrogens from the Krebs cycle to the electron transport chain, facilitating the production of ATP, which is essential for cellular energy production.

The most likely van't Hoff factor for a 0.01 M \($CaI_2$\) solution is 3.00, as indicated in the answer key. This is because each mole that dissolves produces three moles of particles in solution, consisting of one \(Ca^{2+}\) and two I- ions.
