Explanation:
a sealed vessel, containing NO2 and CO2 gases has a total pressure of 2558g mmHg. what is the partial pressure (in mmHg) if the partial pressure of CO2 is 795 mmHg
The partial pressure (in mmHg) if the partial pressure of CO2 is 795 mmHg is given as 1763 mmHg.
How to solve for the partial pressureTo find the partial pressure of NO2, we can use the formula:
total pressure = partial pressure of NO2 + partial pressure of CO2
We know that the total pressure is 2558 mmHg, and the partial pressure of CO2 is 795 mmHg. Plugging these values into the formula, we get:
2558 mmHg = partial pressure of NO2 + 795 mmHg
To solve for the partial pressure of NO2, we can subtract 795 mmHg from both sides:
2558 mmHg - 795 mmHg = partial pressure of NO2
This gives us:
1763 mmHg = partial pressure of NO2
Therefore, the partial pressure of NO2 is 1763 mmHg.

Polyethylene is 86.0% C and 14.0%
H. Determine the empirical formula of the compound.
Percent to Mass: How many grams of C/and Hare present in 100.0 g?
The empirical formula of polyethylene can be determined by converting the given percentages of carbon (C) and hydrogen (H) into grams. To find the grams of each element, we assume a 100.0 g sample of polyethylene.
For carbon:
Mass of carbon = 86.0% × 100.0 g = 86.0 g
For hydrogen:
Mass of hydrogen = 14.0% × 100.0 g = 14.0 g
Therefore, in a 100.0 g sample of polyethylene, there are 86.0 grams of carbon and 14.0 grams of hydrogen.
The empirical formula of a compound represents the simplest whole-number ratio of atoms present in the compound. To determine the empirical formula, we need to find the ratio of carbon to hydrogen in terms of moles.
First, we convert the masses of carbon and hydrogen into moles using their respective molar masses. The molar mass of carbon is approximately 12.01 g/mol, and the molar mass of hydrogen is approximately 1.008 g/mol.
Number of moles of carbon = 86.0 g / 12.01 g/mol ≈ 7.162 mol
Number of moles of hydrogen = 14.0 g / 1.008 g/mol ≈ 13.89 mol
Next, we divide the number of moles of each element by the smallest number of moles to get a simplified ratio.
Carbon: Hydrogen ≈ 7.162 mol : 13.89 mol ≈ 1 : 1.939
Since we want to express the ratio in whole numbers, we multiply both sides by 2 to get a whole number ratio.
Carbon: Hydrogen ≈ 2 : 3.878
Rounding to the nearest whole number, we find that the empirical formula of polyethylene is CH₂.

How much water has to be evaporated from 250 mL of 1 M Ca(OH)2 to make it 3 M?
Approximately 166.67 mL of water needs to be evaporated from 250 mL of 1 M Ca(OH)2 to make it 3 M.
To find the amount of water that needs to be evaporatedThe relationship between the initial and final concentrations and volumes must be taken into account.
Given: Initial concentration \((C^1) = 1 M Initial volume (V^1) = 250 mL\)
\((C^2) = 3 M final concentration\)
We can use the equation:
\(C^1 * V^1 = C^2 * V^2\)
Where:
\(V^2\)is the final volume of the solution
Rearranging the equation to solve for V2:
\(V^2 = (C^1 * V^1) / C^2\)
Substituting the given values:
\(V^2 = (1 M * 250 mL) / 3 M\)
\(V^2 = 250 mL / 3\)
\(V^2\) ≈ \(83.33 mL\)
To find the amount of water that needs to be evaporated, we subtract the final volume from the initial volume:
Amount of water to be evaporated = \(V^1 - V^2\)
Amount of water to be evaporated = 250 mL - 83.33 mL
Amount of water to be evaporated ≈ 166.67 mL
Therefore, approximately 166.67 mL of water needs to be evaporated from 250 mL of 1 M Ca(OH)2 to make it 3 M.

Given that oxygen -16 and oxygen -18 both havean atomic number of 8, how many electrons, protons and neutrons do these oxygen atoms contain
Oxygen-16: 8 protons, 8 neutrons, 8 electrons
Oxygen-18: 8 protons, 10 neutrons, 8 electrons
Explanation:Using atomic and mass numbers, we can find information about the makeup of atoms.
Protons
Every element has a unique number of protons, and every atom of the same element will have the same number of protons. This means that both oxygen atoms must have the same number of protons. The number of protons in an element is equal to its atomic number. Since oxygen has an atomic number of 8, all oxygen atoms will have 8 protons. This means that oxygen-16 and oxygen-18 have 8 protons.
Neutrons
The number of neutrons an atom of a certain element can have varies. Atoms of the same element that have different numbers of neutrons are known as isotopes. The number of neutrons can be found through the mass number. The mass number is the number that follows the dash in the name of the isotope. This number is equal to the protons plus the neutrons. So, to find the number of neutrons in an oxygen atom, subtract 8 protons from the mass number. This means oxygen-16 has 8 neutrons and oxygen-18 has 10 neutrons.
Electrons
Remember that electrons are negatively charged, protons are positively charged, and neutrons have no charge. The number of electrons in an atom determines the charge of the atom. If the number of electrons equals the number of protons, then the charge of the atom will equal 0. If there are more electrons, then the atom will be negatively charged and vice versa. Since neither of the atoms has any indication of a nonzero charge, the number of electrons must equal the number of protons. So, both oxygen atoms have 8 electrons.

Answer:
Explanation:
The standard molar mass is:
For (S )-1-chloro-4-ethyl-2-methylhexane = 162.5 g/mol
For triphenylphosphine = 262 g/mol
For ( S )-1-chloro-4-ethyl-2-methyl triphenylphosphonium = 424.5 g/mol
The mass required for 81% yield = \(\dfrac{81}{100} \times Theoretical \ yield = 4.15 g\)
Theoretical yield = \(\dfrac{4.15}{0.81}\)
= 5.1235 g
thus, since 424.5 g yield produce from 162.5 g
∴
5.1235 g yield will produce = \(\dfrac{162.5}{424.5}\times 5.1235 \ g\)
= 1.9613 g of alkyl halide (-chloro) required.
Also, since 424.5 g yield produce from 262 g phosphine
∴
5.1235 g yield will produce = \(\dfrac{262}{424.5}\times 5.1235 \ g\)
= 3.1622 g of triphenylphosphine required.

Calculate the concentration of an aqueous solution of Ca(OH)2
that has a pH
of 11.67.
Ca(OH)2 in an aqueous solution with a pH of 11.67 has a concentration of 2.50 x 10(-3) M.
What is the pH based on the Ca OH 2 concentration?The calcium hydroxide aqueous solution has a pH of 11.03. Two moles of hydroxide ions are created from one mole of an aqueous solution of calcium hydroxide.
The pH of a solution can be related to the concentration of hydroxide ions ([OH-]) through the equation: pH + pOH = 14
We can rearrange this equation to solve for [OH-]: [OH-] = 10^(-pOH)
Thus: Ca(OH)2 → Ca^2+ + 2 OH-
Since the molar ratio of Ca(OH)2 to [OH-] is 1:2, the concentration of hydroxide ions in the saturated solution can be calculated as follows:
[OH-] = 2 x [Ca(OH)2]
Now we can use the pH value given in the problem to calculate the pOH:
pOH = 14 - pH
pOH = 14 - 11.67
pOH = 2.33
Substituting this value into the equation for [OH-]:
[OH-] = 10^(-pOH)
[OH-] = 10^(-2.33)
[OH-] = 5.01 x 10^(-3) M
In order to get the concentration of the solution, we can apply the equation for the concentration of hydroxide ions in a saturated solution of Ca(OH)2:
[Ca(OH)2] = [OH-] / 2
[Ca(OH)2] = 5.01 x 10^(-3) M / 2
[Ca(OH)2] = 2.50 x 10^(-3) M

That means:
2CP/5 = 2CV/3
3/5 = CV / CP
As CP of Argon is 20.79 J K ⁻¹mol⁻¹, CV will be:
3/5 = CV / CP
3/5 = CV / 20.79 J K ⁻¹mol⁻¹
12.47 J K ⁻¹mol⁻¹ = CV
Constant-volume molar heat capacity of argon is 12.47 J K ⁻¹mol⁻¹Stamples of heterogeneous equilibria. FeO(s) + CO(g) = Fe(s) + CO₂(g) II. H₂(g) L₂(g) = 2HI(g) III. CO₂(g) + C(s) = 2CO(g) IV. N₂(g) 3H₂(g) + 2NH3(g) Identify I.
An example of heterogeneous equilibrium is:
I. FeO(s) + CO(g) ⇌ Fe(s) + CO₂(g)What is heterogeneous equilibrium?Heterogeneous equilibrium refers to an equilibrium state in a chemical reaction where the reactants and products exist in different physical states or phases. It occurs when substances in different phases, such as solids, liquids, and gases, are involved in a chemical reaction.
Considering the given equations:
The equation I: FeO(s) + CO(g) ⇌ Fe(s) + CO₂(g) represents a heterogeneous equilibrium.
This is because the reactants and products involve different phases (solid and gas). FeO is a solid (s), CO is a gas (g), Fe is a solid (s), and CO₂ is a gas (g). The reaction involves the conversion of a solid and a gas to another solid and a gas, and the equilibrium is established between these different phases.
