Answer:

Q<K so N2(g) +3H2(g) → 2NH3(g)

Explanation:

Step 1: Data given

For the balanced equation N2(g)+3H2(g)⇌2NH3(g) We have the following data:

⇒ Reaction quotient Q = 3.56 *10^-4

Where Q is defined as Q = [NH3]^2/{[N2]*[H2]^3]

⇒ Equilibrium constant K = 6.02 * 10^-2

If we compare Q and K, there are 3 options

⇒ Q > K : The reaction favors the reactants. This means that in the Q equation, the ratio of the concentration or pressure of the products) to the concentration or pressure of the reactants is larger than that for K.

This means that more products are present than there would be at equilibrium.

Following Le chatelier's principle reactions always tend toward equilibrium, this means the reaction will produce more reactants from the excess products, and will therefore cause the system to shift to the LEFT.

Doing this, it will allow the system to reach equilibrium.

⇒ Q = K : The reaction is already at equilibrium. There is no tendency to form more reactants or more products at this point. No side is favored and no shift will occur.

⇒ Q < K : The reaction favors the products. The ratio of products to reactants is less than that for the system at equilibrium—the concentration or the pressure of the reactants is greater than the concentration or pressure of the products.

Following Le chatelier's principle reactions always tend toward equilibrium, the system shifts to the RIGHT to make more products.

In this case K > Q since 6.02*10^-2 > 3.56*10^-4

This means that forward reaction will be favored or the reaction will shift to the right

N2(g) +3H2(g) → 2NH3(g)

As a result, the reaction will consume nitrogen gas (N2) and hydrogen gas (H2), and produce more ammonia (NH3).

The reaction will proceed in this direction until equilibrium is established

Determine the pH of 1.0 x 10-10M NaOH pH=

Mrrafil [7]

Answer:

4

Explanation:

Applying,

pH = 14-pOH.................... Equation 1

But,

pOH = -log(OH⁻)

Where OH⁻ = Hydroxyl ion concentration of NaOH.

From the question,

Given: OH⁻ = (1×10⁻¹⁰) M

Substitute these values into equation 1

pH = 14-log((1×10⁻¹⁰)

pH = 14-10

pH = 4

Hence the pH of NaOH with a molarity of 1.0 x 10-10M = 4

Which statement best describes the compressibility of a gas? A Increasing the temperature of a gas decreases the pressure. B Inc

k0ka [10]

The answer is C. Compressing the air reduces the volume and increases the pressure. Compressing the air causes the molecules to collide with one another, and with the walls of the container, at a higher frequency. This is becaue the number of molecules are still the same but now forced in a smaller volume of space. This why the pressure increases wiht reduced volume, while keeping the temperatures constant.

If the energy difference between two electronic states is 214.68 kJ / mol , calculate the frequency of light emitted when an ele

atroni [7]

${\qquad\qquad\huge\underline{{\sf Answer}}}$

Here we go ~

Energy difference btween the two electronic states can be expressed as :

${ \qquad \sf \dashrightarrow \: \Delta E = h\nu}$

[ h = planks constant, ${\: \nu }$ = frequency ]

$\qquad \sf \dashrightarrow \:214.68 = 39.79 \times 10 {}^{ - 14} \times \nu$

$\qquad \sf \dashrightarrow \: \nu = \cfrac{214.68}{39.79 \times 10 {}^{ - 4} }$

$\qquad \sf \dashrightarrow \: \nu = \cfrac{214.68}{39.79 } \times 10 {}^{14}$

$\qquad \sf \dashrightarrow \: \nu \approx 5.395 \times10 {}^{14} \:\:hertz$

Summarize the five points of Dalton’s atomic theory, and explain at least one change that occurred to the atomic theory because

Umnica [9.8K]

The postulates of Dalton's theory were:
1) Elements are made of extremely small particles called atoms
2) Atoms of a given element are identical in size, mass, and other properties
3) Atoms cannot be subdivided, created, or destroyed
4) Atoms combine in whole number ratio to form compounds
5) Chemical reactions are the rearrangement of atoms
The third postulate has been disproved by modern science, in which the atom has been split and been subdivided into smaller parts such as the neutron, proton and electron, which are further subdivided into quarks, gluons, and kaons.
The second postulate was also disproved upon the discovery of isotopes.
