A 5-column table with 2 rows. Column 1 is labeled number of protons, with entries A and D; column 2 is number of neutrons, with
pogonyaev

Answer:

A = 8

B = 8

C = Oxygen (O)

D = 26

E = 30

F = Iron (Fe)

Explanation:

protons    neutrons    atomic number    mass number     element

A               7                 B                           15                        C

D               E                 26                         56                       F

mass number = protons + neutrons

E = 56 - 26 = 30

A = 15 - 7 = 8

protons = atomic number

B = 8

D = 26

From atomic number:

C = Oxygen (O)

F = Iron (Fe)

A 1.00-L flask was filled with 2.00 moles of gaseous SO2 and 2.00 moles of gaseous NO2 and heated. After equilibrium was reached
antiseptic1488 [7]

Answer:

K = 3.45

Explanation:

In the reaction:

SO₂(g) + NO₂(g) ⇄ SO₃(g) + NO(g)

And K is:

K = [SO₃] [NO] / [SO₂] [NO₂]

<em>Where [] are concentrations in equilibrium, as volume is 1L, [] could be taken as moles.</em>

Equilibrium concentrations are:

[SO₂] = 2.00 moles - X

[NO₂] = 2.00 moles - X

[SO₃] = X

[NO] = X

AS moles of NO are 1.3 moles, X = 1.3 moles

Replacing:

[SO₂] = 0.7 moles = 0.7M

[NO₂] = 0.7M

[SO₃] = 1.3M

[NO] = 1.3M

K = 1.3M² / 0.7M²

<h3>K = 3.45</h3>
