Hydrogen sulfide will burn \in three different ways, depending upon the amount of oxygen present. In one reaction, sulfur dioxide and water are produced. In the second reaction, water, sulfur dioxide, and sulfur are produced. The third reaction produces water and sulfur. What is maximum amount of sulfur dioxide that can be produced with 50.0g of hydrogen
The term mole concept is used here to determine the mass of sulfur dioxide.The mass of sulfur dioxide obtained from 50.0 g of hydrogen sulphide is 93.93 g.
One mole of a substance is defined as that quantity of it which contains as many entities as there are atoms exactly in 12 g of carbon - 12. The formula used to calculate the number of moles is:
Number of moles = Given mass / Molar mass
Here balanced reaction is:
2H₂S + 3O₂ → 2SO₂ + 2H₂O
n (H₂S) = n(SO₂)
n = 50.0 / 34.1 = 1.466
Molar mass of sulfur dioxide = 64.067 g/mol
Mass = n × M
m = 1.466 × 64.067 = 93.93 g

Thank you
Answer:
Please mark me brainliest
Explanation:
The answer is false.
opaque materials do not reflect any light because they absorb or trap all light that comes in contact with them. No light is able to return from within an opaque material or reflect off its inner surface. Opaqueness is defined by a lack of light reflection, transmission or scattering. Light either disappears or is converted into other forms of energy within opaque substances.
Please let me know if this helps explain why opaque materials do not reflect light or if any part of the description is unclear. I can also provide any additional examples or details if needed.
Answer: 19) False. A totally opaque material does not let any light pass through it.

The compound oxygen difluoride is quite reactive, giving oxygen and HF when treated with water.
OF2(g) + H2O(g) -> O2(g) + 2HF(g)
E rxn = –318 kJ
Using bond energies, calculate the bond dissociation energy of the O–F bond in OF2
The compound oxygen difluoride is quite reactive, giving oxygen and HF when treated with water. -126kj is the bond dissociation energy of the O–F bond in OF[tex]_2[/tex].
The amount of energy necessary to homolytically shatter a chemical bond is known as bond dissociation energy. Radical species are often produced by a homolytic fracture. The abbreviations BDE, D0, and DH° are used to denote this energy.
Bond dissociation power is frequently used to gauge a chemical bond's strength as well as for contrasting different bonds. Be aware that the enthalpy change depends on the temperature. Bond dissociation energy is often measured in kJ/mol or kcal/mol.
-318 kJ/mol = BDE for OF[tex]_2[/tex]+ BDE for H[tex]_2[/tex]O - BDE for O[tex]_2[/tex] - 2 x BDE for HF.
Substituting all the values, we get
BDE of O–F bond = -126kj

Convert Celsius to Kelvin (C+273.15=K)

What is the mass of 6.02 x 1024 molecules of the compound HCl?
Answer:
First, we need to determine the molar mass of HCl.
The molar mass of HCl = the mass of hydrogen (1.008 g/mol) + the mass of chlorine (35.45 g/mol) = 36.45 g/mol.
Next, we can use Avogadro's number (6.02 x 10^23 molecules/mol) to convert the number of molecules to moles:
6.02 x 10^24 molecules / 6.02 x 10^23 molecules/mol = 10 moles
Finally, we can use the molar mass to convert moles to grams:
10 moles x 36.45 g/mol = 364.5 grams
Therefore, the mass of 6.02 x 10^24 molecules of HCl is 364.5 grams.

If you mixed three plastic cup's contents containing 0,05 L of IM Kool-Aid, 0.05 L of 2.5M Kool-Aid, and 0.05 L of 0.5M Kool-Aid, what would the molarity be of the resulting solution?
The resultant solution has a molarity of 1 M.
How to determine molarity?To find the molarity of the resulting solution, calculate the total amount of moles of Kool-Aid and the total volume of the solution.
The moles of Kool-Aid in each cup can be calculated as:
moles = concentration (M) × volume (L)
Cup 1: moles = 0.05 L × 0 M = 0 mol
Cup 2: moles = 0.05 L × 2.5 M = 0.125 mol
Cup 3: moles = 0.05 L × 0.5 M = 0.025 mol
The total amount of moles is:
total moles = moles in cup 1 + moles in cup 2 + moles in cup 3
total moles = 0 mol + 0.125 mol + 0.025 mol
total moles = 0.15 mol
The total volume of the solution is:
total volume = volume in cup 1 + volume in cup 2 + volume in cup 3
total volume = 0.05 L + 0.05 L + 0.05 L
total volume = 0.15 L
Now calculate the molarity of the resulting solution:
molarity = total moles ÷ total volume
molarity = 0.15 mol ÷ 0.15 L
molarity = 1 M

In this reaction 10.8 moles of carbon dioxide was produced. 10.8moles of carbon monoxide used in this reaction to produce such number of moles of carbon dioxide.
In chemistry, a mole, usually spelt mol, is a common scientific measurement unit for significant amounts of very small objects like molecules, atoms, or other predetermined particles. The mole designates 6.02214076 1023 units, which is a very large number.
For the Worldwide System of Units (SI), the mole is defined as this number as of May 20, 2019, according to the General Convention on Measurements and Weights. The total amount of atoms discovered through experimentation to be present in 12 grammes of carbon-12 was originally used to define the mole.
2CO(g)+O[tex]_2[/tex](g)=2CO[tex]_2[/tex](g)
moles of carbon dioxide= 10.8 moles
According to stoichiometry
moles of carbon monoxide= (2/2)× 10.8 =10.8moles.

what is the starting concentration of the Cu+ solution
A mixture of He , Ar , and Xe has a total pressure of 2.10 atm . The partial pressure of He is 0.250 atm , and the partial pressure of Ar is 0.300 atm . What is the partial pressure of Xe ? Express your answer to three significant figures and include the appropriate units.
The partial pressure of the gas in a mixture is the pressure that the gas would exert if present alone in the vessel at the same temperature as that of the mixture. Here the partial pressure of Xe is
The pressure exerted by a mixture of two or more non-reacting gases enclosed in a definite volume is equal to the sum of the partial pressures of the component gases.
According to Dalton's law of partial pressures, total pressure is:
P = p₁ + p₂ + ...
2.10 = 0.250 + 0.300 + p
p = 1.55
Partial pressure of Xe = 1.55
