A mixture of 0.0375 g of hydrogen and 0.0185 mol of oxygen in a closed container is sparked to initiate a reaction. How many grams of water can form? Which reactant is in excess, and how many grams of it remain after the reaction?

Answers

Answer 1

What is Limiting Reagent?

In a chemical process, the limiting reagent is a reactant that is completely consumed when the reaction is complete. This reagent limits the amount of product generated because the reaction cannot continue without it.

Main Content

The solution relies on a limiting reagent.

Step 1:

The balanced equation is

2\(H_{2} O(l)\) from the moles of \(H_{2}\) if we consider \(O_{2}\) is limiting reagent:

Given that,

The mass of H\(_{2}\) =0.0375 g

We know that,

The moles of H\(_{2}\) = (0.0375 g H\(_{2}\)) \(\times\) \(\frac{1.0 mol H_{2} }{2.o16gH_{2} }\) = 0.01860 mol H\(_{2}\)

Moles of H\(_{2}\)O\((l)\)from H\(_{2}\)=(0.01860 mol H\(_{2}\) \(\times\) \(\frac{20 mol of H_{2}O(l) }{2.0 mol H_{2} }\) = 0.01860 mol H\(_{2}\)O

Thus, 0.01860 mol H\(_{2}\)O(l) is formed from 0.0375 g of hydrogen if we consider O\(_{2}\) is limiting reagent.

What neutral atom has a nuclear charge of +9, and a nuclear mass of 19 amu? How many neutrons does it have. How many electrons does it have ?

Answers

The neutral atom with a nuclear charge of +9 and a nuclear mass of 19 amu is fluorine-19. It has 10 neutrons and 9 electrons.

The atomic number of an element is equal to the number of protons in its nucleus. Therefore, if an atom has a nuclear charge of +9, it means it has 9 protons. The nuclear mass of an atom is the sum of its protons and neutrons. Since we know the nuclear mass of this atom is 19 amu, and it has 9 protons, it must have 10 neutrons (19 - 9 = 10).

To determine the number of electrons, we need to know the charge of the atom. Since it is a neutral atom, it has no net charge. This means the number of electrons must be equal to the number of protons, which is 9.

Therefore, the identity of the neutral atom is fluorine-19, with 9 protons, 10 neutrons, and 9 electrons.

A certain amount of hydrogen peroxide was dissolved in 100. ml of water and then titrated with 1.68 m kmno4. what mass of h2o2 was dissolved if the titration required 21 ml of the kmno4 solution?

Answers

The mass of H2O2 dissolved is not directly provided in the given information. Additional calculations or data are required to determine the mass of H2O2 dissolved.

The mass of hydrogen peroxide (H2O2) dissolved in 100 ml of water is calculated to be approximately X grams.

To determine the mass of H2O2 dissolved, we can use the balanced chemical equation for the reaction between hydrogen peroxide and potassium permanganate:

5H2O2 + 2KMnO4 + 3H2SO4 → 5O2 + 2MnSO4 + 3H2O + K2SO4

From the balanced equation, we can see that the mole ratio between H2O2 and KMnO4 is 5:2.

Given that 21 ml of 1.68 M KMnO4 solution was required for the titration, we can calculate the number of moles of KMnO4 used:

Volume of KMnO4 solution = 21 ml = 0.021 L

Molarity of KMnO4 solution = 1.68 M

Number of moles of KMnO4 = Molarity × Volume

= 1.68 M × 0.021 L

= 0.03528 moles

Using the mole ratio, we can determine the number of moles of H2O2:

Number of moles of H2O2 = (5/2) × Number of moles of KMnO4

= (5/2) × 0.03528 moles

To convert moles of H2O2 to grams, we need to multiply by its molar mass. The molar mass of H2O2 is approximately 34.02 g/mol.

Mass of H2O2 = Number of moles of H2O2 × Molar mass of H2O2

= (5/2) × 0.03528 moles × 34.02 g/mole

The mass of hydrogen peroxide (H2O2) dissolved in 100 ml of water is approximately X grams. This value was determined by titrating the H2O2 solution with a 1.68 M KMnO4 solution, and the titration required 21 ml of the KMnO4 solution. The calculation involved using the balanced chemical equation, molar ratios, and the molar mass of H2O2 to convert the volume of KMnO4 used to the mass of H2O2 dissolved.

what is the purpose of precipitation ag and pb2 out of solution at the beginning of the procedure?

Answers

The purpose of precipitating Ag (silver) and Pb^2+ (lead) out of the solution at the beginning of the procedure is to separate and isolate these ions from other components present in the mixture. This allows for a more accurate analysis and identification of the remaining ions in the solution.

Here's a step-by-step explanation of the process:

1. Add a suitable reagent, such as hydrochloric acid (HCl), to the solution containing the mixture of ions, including Ag and Pb^2+. This reagent reacts with the silver and lead ions to form their respective insoluble chlorides (AgCl and PbCl2).


2. As the reagent is added, the Ag and Pb^2+ ions combine with the chloride ions (Cl-) from the reagent, resulting in the formation of solid precipitates: AgCl (silver chloride) and PbCl2 (lead chloride). The reaction equations are as follows:
  Ag+ + Cl- → AgCl (s)
  Pb^2+ + 2Cl- → PbCl2 (s)


3. These solid precipitates can then be separated from the solution through a process such as filtration or centrifugation. This step removes the AgCl and PbCl2 solids from the solution, leaving behind a mixture of the other ions.


4. With the Ag and Pb^2+ ions now separated from the solution, it is easier to identify and analyze the remaining ions present in the mixture. The absence of silver and lead ions prevents any interference in further tests and ensures more accurate results.


In summary, the purpose of precipitating Ag and Pb^2+ out of the solution at the beginning of the procedure is to isolate these ions from the rest of the components in the mixture, allowing for more accurate analysis and identification of the remaining ions.

This is achieved by adding a reagent like HCl, forming insoluble chlorides, and then separating the solid precipitates through filtration or centrifugation.

A sample of certain gas have Volume of 1.25 L ATM _125 degree Celsius and5.0 ATM the gas is compressed 50.0 ATM a volume of 325 mL. what is final temperature?

Answers

The final temperature of the gas is approximately 40.96 Kelvin.

To determine the final temperature of the gas, we can use the ideal gas law, which states:

PV = nRT

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

First, let's convert the given temperatures to Kelvin. We have:

Initial temperature: -125 degrees Celsius = 148 K (approximate)

Final temperature: Unknown

The initial conditions of the gas are as follows:

Initial pressure (P1) = 1.25 atm

Initial volume (V1) = 1250 mL = 1.25 L (since 1 L = 1000 mL)

Initial temperature (T1) = 148 K

The final conditions of the gas are as follows:

Final pressure (P2) = 50.0 atm

Final volume (V2) = 325 mL = 0.325 L

Final temperature (T2) = Unknown

Using the ideal gas law, we can set up the following equation:

(P1 * V1) / T1 = (P2 * V2) / T2

Substituting the known values:

(1.25 atm * 1.25 L) / 148 K = (50.0 atm * 0.325 L) / T2

Simplifying the equation:

T2 = (50.0 atm * 0.325 L * 148 K) / (1.25 atm * 1.25 L)

T2 = 40.96 K

Calculate the minimum of oxygen required for the complete combustion of a mixture of 20cm³ of CO (Carbon Monoxide) and 20cm³ of H₂ (Hydrogen gas)​

Answers

The minimum amount of oxygen required for the complete combustion of 20cm³ of CO and 20cm³ of H₂ would be 20.16 cm³ at STP.

Stoichiometric problem

The balanced chemical equation for the combustion of CO and H2 is:

CO + 1/2O2 → CO2

H2 + 1/2O2 → H2O

From the equation, we can see that one mole of CO requires 1/2 mole of O2, while one mole of H2 requires 1/2 mole of O2.

20 cm³ CO at STP = 20/24000 = 0.00083 moles CO20 cm³ H2 at STP = 20/24000 = 0.00083 moles H2

From the balanced equation, we can see that each mole of CO requires 1/2 mole of O2, while each mole of H2 requires 1/2 mole of O2.

Therefore, we need 0.00083/2 = 0.00042 moles of O2 for the combustion of CO and the same amount for the combustion of H2.

The total amount of O2 required is the sum of the amounts needed for each reactant:

Total O2 required = 0.00042 + 0.00042 = 0.00084 moles0.00084 moles O2 × 24000 cm³/mol = 20.16 cm³ O2

Therefore, the minimum amount of oxygen required for the complete combustion of 20 cm³ of CO and 20 cm³ of H2 is approximately 20.16 cm³ at STP.

Answers

Ionic ligands like chloride have a higher crystal field splitting energy () than molecular ligands like carbon monoxide, CO. In general, this statement is accurate. Tetrahedral complexes have a higher crystal field splitting energy () than octahedral complexes. In general, this statement is accurate.

When a metal ion interacts with ligands in a complex, the energy difference between its d-orbitals is known as the crystal field splitting energy (). Let's assess each assertion:

Ionic ligands like chloride have a higher crystal field splitting energy () than molecular ligands like carbon monoxide, CO.

In general, this statement is accurate. In contrast to molecular ligands like carbon monoxide, ionic ligands like chloride have a stronger electrostatic contact with the metal ion. This results in a higher crystal field splitting energy.

The metal, but not the ligand, affects the crystal field splitting energy ().

This claim is untrue. The metal ion and its surrounding ligands both affect the crystal field splitting energy. The magnitude of is affected in diverse ways by various metals and ligands.

Tetrahedral complexes have a higher crystal field splitting energy () than octahedral complexes.

In general, this statement is accurate. Compared to tetrahedral complexes, octahedral complexes have a higher degree of splitting in the d-orbitals. So, for octahedral compounds, the crystal field splitting energy is higher.

The hue of a complex is determined by the energy of the crystal field splitting ().

This assertion is accurate. The energy difference between the d-orbitals is influenced by the size of the crystal field splitting energy, which in turn impacts the absorption of light. The complex's distinctive color is caused by the light that is absorbed, which is related to specific wavelengths.

The charge of a complex is determined by the crystal field splitting energy ().

This claim is untrue. The complex's electronic structure is related to the crystal field splitting energy but does not directly affect the charge. The total charge of the metal ion and the ligands it is coordinated with determine the charge of a complex.

Answers

For standard 1, the volume of stock solution required is 2.00 mL, while for standard 2, it is 4.00 mL.

In order to calculate the volume of 0.0315 m Bromocresol green (HBCG) standard stock solution required to make 10.00 ml of the three standards, we need to use the formula:

M1V1 = M2V2

Where M1 is the concentration of the stock solution,

V1 is the volume of the stock solution required,

M2 is the concentration of the final solution, and

V2 is the final volume of the solution.

To calculate the volume of 0.0315 m Bromocresol green (HBCG) stock solution required to make 10.00 ml of 0.00630 m Bromocresol green (HBCG) standard 1, we can plug in the values into the formula as:

M1V1 = M2V2V1 = (M2V2)/M1= (0.00630 mol/L x 0.01000 L)/0.0315 mol/L= 0.00200 L = 2.00 mL

Therefore, the volume of 0.0315 m Bromocresol green (HBCG) stock solution required to make 10.00 ml of 0.00630 m Bromocresol green (HBCG) standard 1 is 2.00 mL.

To calculate the volume of 0.0315 m Bromocresol green (HBCG) stock solution required to make 10.00 ml of 0.0126 m Bromocresol green (HBCG) standard 2, we can use the same formula as above:

M1V1 = M2V2V1 = (M2V2)/M1= (0.0126 mol/L x 0.01000 L)/0.0315 mol/L= 0.00400 L = 4.00 mL

Therefore, the volume of 0.0315 m Bromocresol green (HBCG) stock solution required to make 10.00 ml of 0.0126 m Bromocresol green (HBCG) standard 2 is 4.00 mL.

In conclusion, we can use the formula M1V1 = M2V2 to calculate the volume of 0.0315 m Bromocresol green (HBCG) stock solution required to make different standards.

this reaction is an example of conjugate addition of a nucleophile to an α,β-unsaturated carbonyl.

Answers

Yes, it is correct, this reaction is an example of conjugate addition of a nucleophile to an α,β-unsaturated carbonyl.

In this type of reaction, a nucleophile attacks the carbon atom in the carbonyl group that is adjacent to the double bond (the α-carbon), forming a new carbon-carbon bond and creating a tetrahedral intermediate. The intermediate then collapses, resulting in the formation of a new carbon-carbon bond and the addition of the nucleophile to the double bond. An α,β-unsaturated carbonyl is a compound that contains a carbonyl group (C=O) and a double bond (C=C) in which the carbonyl carbon (C=O) and the double-bonded carbon (C=C) are adjacent to each other. An example of an α,β-unsaturated carbonyl compound is an unsaturated aldehyde or unsaturated ketone. These compounds are highly reactive and can undergo a variety of reactions such as conjugate addition, electrophilic addition, and nucleophilic addition reactions.

The features that make H₂O a polar molecule are:

The molecule has a bent molecular shape.The molecule has an uneven distribution of electron densityThe electrons are distributed unevenly within each bond of the molecule

What is a polar covalent bond?

It is a bond that occurs when the bonding atoms have a difference in electronegativity causing the generation of an area with higher electron density creating a positive pole and a negative pole.

The oxygen atom in water has a partial negative charge, while the hydrogen atoms have a partial positive charge. This results in an overall dipole moment, with the molecule having a slightly positive end and a slightly negative end.

H₂O is a polar molecule due to its bent molecular shape, an uneven distribution of electron density, and uneven electron distribution within each bond of the molecule. This results in an overall electrical charge for the molecule.
