Consider the balanced equation below.
Alex787 [66]

the balanced equation is as follows

2H₂S + 3O₂ --> 2SO₂ + 2H₂O

molar ratio also known as stoichiometry is the ratio in which the reactants and products are either formed or reacted in the given equation

molar ratio can be determined by the coefficients of the compounds in the balanced reaction

coefficient is the number in front of the chemical compound

coefficients for the compounds in this reaction are as follows

H₂S - 2

O₂ - 3

SO₂ - 2

H₂O - 2

therefore correct option is

H₂S:SO₂ = 2:2 and O₂:H₂O = 3:2

Oxygen has an electronegativity of 3.5, and carbon has an electronegativity of 2.5. How is charge distributed on an oxygen atom
Aleksandr [31]

Answer:

The oxygen atom has a slightly negative charge.

Explanation:

3.5 - 2.5 = 1

For ionic bond electronegativity should be more than 1.6.

So, O and C do not have whole charge. Electronegativity of O more than C, so electrons slightly moved to the oxygen side.

A diffusion coefficient KG was determined for the diffusion of a gas A through a stagnant film B [KG = 0.88 mol//h-ft2-atm].
Angelina_Jolie [31]

Explanation:

Transfer of mass A into stagnant film B depends on the availability of driving force.

Whereas driving force is the pressure difference at the surface of A and the bulk.

As,       N_{A} \propto (P_{A1} - P_{A2})

           N_{A} = K_{G} \times (P_{A1} - P_{A2})

Therefore, putting the given values into the above formula as follows.

         N_{A} = K_{G} \times (P_{A1} - P_{A2})

                     = 0.88 \times (0.2 atm - 0.05 atm)

                     = 0.132 mol/h.ft^{2}

Thus, we can conclude that the flux of A from a surface into a mixture of A and B is 0.132 mol/h.ft^{2}

A binding protein binds to a ligand l with a kd of 400 nm. what is the concentration of ligand when y is (a) 0.25, (b) 0.6, (c)
lilavasa [31]

Hey there!:

The fractional saturation y is defined as :

y =  [ L ] / Kd + [ L ]

where :

[ L ] = concentration of binding ligand

Kd = 400 nm
