Answer:

P[H2] = P[I2] = 0.02 atm

P[HI] = 5.98 atm

Explanation:

The ICE table for the given reaction is:

                H2(g)   +      I2(g)      ↔     2HI(g)

Initial       3.01atm       3.01atm            -

Change    -x                 -x                    +2x

Equilib     (3.01-x)        (3.01-x)              2x

The equilibrium constant, Kp is given as:

Kp = \frac{P_{HI}^{2}}{P_{H2}*P_{I2}}

483*10^{2} = \frac{(x)^{2}}{(3.01-x)^{2}}

x = 2.99 atm

Equilibrium partial pressure of H2 = I2 = 3.01-2.99 = 0.02 atm

Equilibrium partial pressure of HI = 2x = 2(2.99) = 5.98 atm

Answer:

Explanation:

There is only room for eight electrons in the second electron shell, so there can only be eight elements in this period, and no room for another section.

What are the reasons for unequal distribution of natural resources?
BARSIC [14]

Explanation:

There are so many reasons why natural resources are unevenly distributed in nature.

The major control on distribution of resource is basically the geologic setting of place.

Here are some of reasons:

  • Geological setting of place: most natural mineral resources are formed in areas where the best interaction between the ore forming processes and the environment occurs. No one can determine or control that.
  • Climate: the climate is the average weather condition of a place over an extended period of time. Different natural resources can be allocated to a place based on the dominant climatic condition in that place.

In which reaction do four total molecules of reactants produce two total molecules of products?
Pachacha [2.7K]

Answer:

option D = N₂ + 3H₂   →   2NH₃

Explanation:

The reaction in which the nitrogen and hydrogen are reacted to form the ammonia is true.

  N₂ + 3H₂   →   2NH₃

In this reaction we can see that one molecules of nitrogen react with three molecules of hydrogen and form two molecules of ammonia.

while the other options are in correct because,

2SO₂  +  O₂    →   2SO₃

In this reaction two molecules of SO₂ react with one molecule of oxygen and form two molecules of SO₃.

2H₂S  +  3O₂   →     2SO₂ + 2H₂O

In this reaction two molecules of H₂S react with three molecules of oxygen and produced four molecules of product.

SnO₂ +  2H₂   →  Sn + 2H₂O

This is also incorrect because three molecules of reactant form three molecules of product.

Refer to the following illustration to answer this Question.
ad-work [718]

Answer:

Option (B) It separates the hydrogen ion (H+) from the chlorine ion (Cl–).

Explanation:

The reaction above simply illustrate the dissociation of HCl when dissolve is water.

When HCl is dissolved in H2O, it will separate into the hydrogen ion, H+ and chloride ion Cl- as shown below

HCl —> H+ + Cl-

The water help to separate the H+ from the Cl-

When 943 J of heat is added to 10 grams of oil at 28˚C , the temperature increases to 89˚C. What is the specific heat of the oil
IgorLugansk [536]

Answer: 1.55 Jg°C

Explanation:

The quantity of Heat Energy (Q) required to heat a substance depends on its Mass (M), specific heat capacity (C) and change in temperature (Φ)

Thus, Q = MCΦ

Since,

Q = 943 joules

Mass of oil = 10g

C = ? (let unknown value be Z)

Φ = (Final temperature - Initial temperature)

= 89°C - 28°C = 61°C

Then, Q = MCΦ

943 J = 10g x Z x 61°C

943J = 610g°C x Z

Z = (943J / 610g°C)

Z = 1.55 Jg°C

Thus, the specific heat of the oil is 1.55 Jg°C
