SO2(g) + NO2(g) ↔ SO3(g) + NO(g) Kc = 0.33 A reaction mixture contains 0.41 M SO2, 0.14 M NO2, 0.12 M SO3 and 0.14 M NO. Which o
stepladder [879]

Answer:

The reaction will shift in the direction of products.

Explanation:

<u>Step 1:</u> Data given

A reaction mixture contains:

0.41 M SO2

0.14 M NO2

0.12 M SO3

0.14 M NO

<u>Step 2:</u> The balanced equation

O2(g) + NO2(g) ↔ SO3(g) + NO(g)      Kc = 0.33

<u>Step 3:</u> Define the direction of the shift of  reaction:

When Q<K, there are more reactants than products. As a result, some of the reactants will become products, causing the reaction to shift to the right.

When Q>K, there are more products than reactants. To decrease the amount of products, the reaction will shift to the left and produce more reactants.

When Q=K, the system is at equilibrium and there is no shift to either the left or the right.

<u>Step 4:</u> Calculate Q

Q = [NO][SO3]/[SO2][NO2]

Q = (0.14 *0.12)/(0.41*0.14)

Q = 0.0168/0.0574

Q = 0.293

Q<Kc

This means there are more reactants than products. Thud, some of the reactants will become products, causing the reaction to shift to the right.

The reaction will shift in the direction of products.

Biological specimens are often examined by microscopy. However, microscopy with visible light is limited to viewing details of a
Alborosie

Answer:

(a) Wavelength = 4.85 x 10^-12 m

(b) Maximum uncertainty = 5.27*10^-25 kgm/s

Explanation:

(a)  Calculating the wavelength using the formula;

      λ= h/p

but p = mv

Where;

m = mass of electron = 9.1 x 10-31

h = 6.625 x 10^-34

      = h/mv

       = 6.625 x 10^-34 / (9.1 x 10^-31 x 1.5×10^8)

  = 4.85 x 10^-12 m

so, the wavelength is short enough to reveal molecular details at the atomic level.

TIMED HELP PLSPLS ASAP UNDER 5 MIN REMAINING
uysha [10]

Answer:

3.98×10⁻¹⁹ J

Explanation:

Applying,

E = hf................. Equation 1

Where E = energy of the photon, h = planck's constant, f = frequency of the photon

From the question,

Given: f = 6.00×10¹⁴ Hz

Constant: h = 6.626×10⁻³⁴J.s

Substitute these values into equation 1

E = (6.00×10¹⁴)(6.626×10⁻³⁴)

E = 39.756×10⁻²⁰

E = 3.98×10⁻¹⁹ J

Hence the energy of the photon in joules is 3.98×10⁻¹⁹ J
