Answer: The phenomenon of osmosis can be seen in the surrounding as the when the raisins are put into water overnight. The water enters the raisins and it swells.

The osmosis can be defined as the biological phenomenon by which the water or any other liquid enters from an area of its higher concentration to an area of its lower concentration via semi permeable membrane.

Diffusion can take place in between gases and in between gases and liquid.

Exchange of gases in the lungs is an example of diffusion in liquids and burning an incense stick in the room is an example of diffusion in gases.

Nitric oxide, an important pollutant in air, is formed from the elements nitrogen and oxygen at high temperatures, such as those
Elden [556K]

Answer:

The Equilibrium will shift towards the left.

Explanation:

The reaction for the formation of nitric oxide is follows,

N_2(g)+O_2(g)\leftrightarrow2NO(g)

Expression for reaction quotient is as follows,

Q=\frac{[NO]^2}{[N_2][O_2]}

Putting the values according to the data given and calculating reaction quotient for the reaction

Q=0.16

So, the reaction quotient is 0.16.

and the value of K is 0.01 .

Q>K

Since the value of K is less than Q, therefore the reaction will shift towards left.

Light has a wavelength of 34.4 nm. What is its frequency?
pishuonlain [190]
<h2>Answer:    8.69 × 10⁻¹ Hz </h2>

<h3>Explanation: </h3>

Frequency = Speed of Light ÷ Wavelength

                    = (2.99 × 10⁸ m/s) ÷ (3.44 × 10⁻⁸ m)  

                    = 8.69 × 10⁻¹ Hz

The frequency of a light of wavelength 34.4 nm is 8.69 × 10⁻¹ Hz.

<u>Notes:</u>

Hz ≡ /s

1 m = 10⁹ nm

WILL MARK BRAINLIEST!!! Which of the following combinations will result in a reaction that is never spontaneous?
grin007 [14]
2. 

G=H-TS
G=(+)-T(-)
G=(+)+(+)

Since G would be positive no matter what the temperature could be, the reaction could never be spontaneous.
